Best WhatsApp API Providers in Sri Lanka: 12 Compared (2026)

The best WhatsApp API provider in Sri Lanka depends on how you want to pay and who you want to call for help. On prices checked on 28 September 2026, YCloud’s free plan and ChatMitra were the cheapest ways to run a typical month, Bloomwire had the lowest paid plan among Sri Lankan providers (LKR 3,500 a month) with local billing and support, and 360dialog, Twilio and Infobip suit developers. Every provider sends through Meta’s WhatsApp Business Platform, and Meta charges the same per-message rate whichever one you pick. What differs is the plan price, any markup on Meta’s rate, the billing currency and the software.

Below we compare 12 providers in three groups (local, self-serve and developer platforms), starting with the change that matters most this year: Meta’s new Sri Lanka rates.

What changes for Sri Lanka on 1 October 2026

From 1 October 2026, Sri Lanka has its own line on Meta’s WhatsApp rate card, instead of sharing the “Rest of Asia Pacific” price. Meta announced the move on 27 May 2026. Three things change for anyone messaging Sri Lankan numbers:

1. Utility and authentication messages fall about 82%, from $0.0113 to $0.002. That covers order updates, delivery alerts, reminders and one-time passwords. Service messages, newly charged from the same date, cost the same $0.002.
2. Marketing stays at $0.0732, while the Rest of Asia Pacific rate rises to $0.0842.
3. A new authentication-international rate of $0.144 applies to eligible businesses based outside Sri Lanka: 72 times the domestic rate.

Two further changes on the same date apply in every country, Sri Lanka included:

• Service messages are now charged. Replies inside the 24-hour customer service window, free until now, are billed at the utility rate after 1,000 free per business phone number each month (no roll-over).
• Utility templates sent in reply to a customer are charged too, ending an exemption in place since July 2025.

What stays free: messages inside a free entry point window. When someone messages you from a Click-to-WhatsApp ad or a Facebook Page call-to-action button on the WhatsApp phone app, and you reply within 24 hours, a 72-hour window opens in which every message is free.

Meta’s WhatsApp API rates for Sri Lanka

Meta charges per delivered template message, and from October per service message beyond the first 1,000 free each month. The rate depends on the category and the recipient’s country code, not your provider’s location, so a +94 number is billed at the Sri Lanka rate whoever sends it. The exception is the authentication-international rate, which also depends on where your business is based.

Source: Meta’s USD rate cards effective 1 July 2026 and 1 October 2026, linked from developers.facebook.com/docs/whatsapp/pricing (downloaded 28 September 2026). *Converted at the Central Bank of Sri Lanka’s indicative rate of LKR 330.2643 per US dollar on 28 September 2026. Meta doesn’t publish an LKR rate card, so your actual charge depends on your billing currency and your bank’s rate.

Volume tiers lower utility and authentication prices at scale. Counted monthly across your whole business portfolio, Sri Lanka’s utility rate stays at $0.002 for the first 150,000 messages, then steps down to $0.0019 and eventually $0.0015 (−25%) above 50 million. Marketing has no tiers. Meta changes rates only on the first day of a quarter (1 January, 1 April, 1 July or 1 October), so check the current card before you budget.

What a WhatsApp API provider does

A WhatsApp API provider, often called a Business Solution Provider or BSP, connects your business to Meta’s WhatsApp Business Platform and supplies the software around it: number onboarding, template tools, a shared team inbox, broadcasts, chatbots and integrations. The per-message price is Meta’s. Providers differ in what they charge on top (a plan, a per-message fee or a markup), the currency you pay in, and the software and support.

You don’t strictly need one. A business with developers can use Meta’s Cloud API directly and pay only Meta, but then it builds the inbox and tools itself. See WhatsApp Cloud API pricing: direct vs provider.

How we compared the providers

We used only each provider’s own website, read on 28 September 2026, and compared six things: Meta rate transparency (at cost or marked up, and whether Sri Lanka rates are published), entry cost, total cost in our worked example, billing currency, Sri Lanka presence as the provider states it, and features and limits. Partner status is reported as each provider’s own claim. Where a figure isn’t published, we say so rather than estimate.

WhatsApp API providers for Sri Lanka: price comparison (September 2026)

Sources: each provider’s own pricing or Sri Lanka page, checked 28 September 2026 (Wati’s Sri Lanka prices from the pricing data its page loads for LK; AiSensy’s from its linked country rate sheet; Twilio’s from its pricing CSV).

Worked example: a month of WhatsApp for a Colombo online store

Take an online clothing store in Colombo that uses WhatsApp for promotions, order updates, website logins and customer chats. In a typical month from October 2026 it sends:

• 4,000 marketing messages: two broadcasts to 2,000 opted-in customers.
• 6,000 utility messages: order confirmations, dispatch and delivery updates.
• 1,000 authentication messages: login codes for its website.
• 3,000 service messages: replies inside the 24-hour window, of which 1,000 are free.

Marketing is 94% of the bill. Everything else together costs $18. So a 20% markup on marketing adds about $58.56 a month here, more than the gap between most entry plans. Before 1 October the same month would have cost $371.90: service replies were free, but utility and authentication cost $0.0113 each.

Here is the monthly total on each provider’s entry plan that includes broadcasts, using published prices:

*₹0.20 once per contact per 24-hour conversation, including customer-started ones; assumes the maximum of 14,000 (every message opening its own conversation). INR converted at CBSL’s 28 September 2026 rate (LKR 3.4467 per rupee). **AiSensy’s sheet still lists utility at $0.01356 (20% over the old rate), which would make messages $451.08. We assume each provider applies its stated pricing to Meta’s new rates; confirm this. respond.io’s Growth plan is used because broadcasts start there; it prices by monthly active contacts, and this store messages 2,000. SafeNet Creations and Yenasys are excluded (agency fees plus a separate BSP; no published prices).

On published prices, YCloud’s Free plan is cheapest for this month at $310.80 (one user), then Bloomwire at about $321.40 in rupees, then ChatMitra. Apart from respond.io, whose broadcasts need its Growth plan ($239 at this contact count), the at-cost providers sit within about $60 of each other; AiSensy’s markup and Infobip’s all-in rates add the most.

The 12 providers, compared

1. Bloomwire: local platform with LKR pricing

Bloomwire is a Sri Lankan company (registration PV00214667) with an address in Pannipitiya, a +94 phone line and a Sri Lanka-based support team.

• Pricing: Starter LKR 3,500 a month (1 user, 10,000 contacts), Growth LKR 8,500 (3 users), Scale LKR 14,500 (5 users), Enterprise custom. “Free 14-day trial on all plans.” Extra users cost LKR 3,500 each. Meta’s fees are “billed separately by Meta”.
• Features: shared inbox, chatbot automation, bulk campaigns, APIs and webhooks.
• Best for: small Sri Lankan businesses that want rupee invoices and a local team.
• Watch for: business-hours support on Starter (extended hours from Growth); AI credits priced separately (not published); and no Meta partner claim on its site, only a “Meta-verified” API.

2. Yenasys: local builder for banks, government and logistics

Yenasys (Pvt) Ltd is based in Kadawatha and describes itself as a “Meta Business Partner” and official WhatsApp Business Solution Provider.

• Pricing: not published. The only offer on its page is a free 15-minute walkthrough.
• Features: chatbots that “understand free-form questions in Sinhala, Tamil or English”, and bots for banking, government and logistics with CRM and ERP integration.
• Best for: larger organisations that want a custom build by a local team.
• Watch for: no self-serve plan or public prices, so you can’t compare costs without a sales call.

3. SafeNet Creations: local agency, not a BSP

SafeNet Creations is an agency headquartered in Jaffna with Colombo coordination, working in English, Tamil and Sinhala.

• Pricing (effective 10 August 2026, in LKR): “LKR 75,000 setup + LKR 15,000 / month” for API Automation Starter, rising to Integrated Automation Pro from LKR 300,000 setup plus from LKR 65,000 a month (Enterprise is custom-quoted). Prices exclude “Meta messaging charges” and “selected inbox or BSP subscriptions”.
• Best for: businesses that want someone to design and build the automation for them.
• Watch for: you may also need a separate inbox or BSP subscription, which its prices exclude, so add both when comparing.

4. ChatMitra: free plan, Meta’s rates at cost

ChatMitra is an India-based WhatsApp Business API platform that describes itself as a Meta Business Partner. India and Sri Lanka share the same time zone (UTC+5:30), and the platform accepts Sri Lankan (+94) numbers for sign-up, sending and contacts.

• Pricing: Starter is free, Pro is ₹999 a month (about LKR 3,443) with a free trial and, per ChatMitra’s pricing page, 1,000 free messaging credits a month, and Enterprise is ₹2,499 a month (about LKR 8,613). Meta’s charges are billed by Meta directly to your own payment method, at cost. ChatMitra adds ₹0.20 per 24-hour conversation on Starter and Pro; Enterprise has no platform fee.
• Features: broadcasts with tag segments and retargeting, a shared team inbox with role permissions, campaign reports, Shopify and Google Sheets automations, and an Android app. Pro adds auto-replies, an AI chatbot, API access and webhooks.
• Best for: SMBs that want Meta’s rates without a markup and a free way to start.
• Watch for: plans are billed in Indian rupees (check your card can pay in INR); there’s no Sri Lankan office; the template builder offers Tamil but not yet Sinhala; and the dashboard is English-only.

5. YCloud: published Sri Lanka rates, zero markup

YCloud is a global provider that says it is “a Meta Official BSP” and is one of the few to publish a Sri Lanka rate table.

• Pricing: Free plan at $0 (1 user); Growth $39 a month billed yearly ($468); Pro $89; Enterprise $399. Monthly billing costs more. The page headline promises “Zero Mark-up Charges on WhatsApp Messages”.
• Features: coexistence with the WhatsApp Business app, WhatsApp calling and a chatbot builder.
• Watch for: its Sri Lanka table still showed utility at $0.0113 on 28 September, and support hours are 7 a.m. to 4 p.m. Colombo time (UTC+8 office hours).

6. Go4whatsup: Sinhala and Tamil focus

Go4whatsup, run by the Indian company Inwizards, has a dedicated Sri Lanka page and describes itself as a “Meta Business Partner”.

• Pricing: a free-forever plan with limited conversations, and Standard at “$39/month globally” with unlimited agents. It offers “LKR-friendly pricing”, but says “Pay in USD or INR”.
• Features: Sinhala and Tamil auto-translation, nine native integrations and support “in Sinhala or Tamil” over WhatsApp.
• Watch for: its Sri Lanka page says Meta charges “pass through at-cost, shown as a separate line on every invoice”, while its pricing page says “Meta bills you directly”. Ask which applies. It also still describes Meta’s pricing as per conversation, which Meta replaced with per-message pricing in July 2025.

7. Wati: established SMB platform, USD plans

Wati is a widely used SMB platform. For Sri Lanka its pricing data shows USD plans.

• Pricing: Growth $49 a month monthly or $39 a month billed yearly, Pro $99 ($79 yearly), Business $249 ($199 yearly), with a 7-day free trial.
• Features: coexistence with the Business app, Click-to-WhatsApp ad tools and AI agents.
• Watch for: Growth includes 3 users with no add-ons, and the rate card linked from its pricing page on 28 September was an INR sheet dated November 2024, so its current Sri Lanka message prices weren’t published.

8. AiSensy: broad marketing toolkit, 20% markup

AiSensy offers a USD price list and a country rate sheet that includes Sri Lanka.

• Pricing: Free Forever at $0 (no broadcasts), Basic $45 a month, Pro $99; 5% off quarterly and 10% off yearly.
• Message rates: its sheet lists Sri Lanka marketing at $0.08784 and utility and authentication at $0.01356, exactly 20% above Meta’s pre-October rates.
• Watch for: that’s $0.0146 more than Meta on every marketing message.

9. respond.io: omnichannel inbox

respond.io combines WhatsApp with other channels in one inbox and promises “No setup fees or markups; pay only what Meta charges”.

• Pricing: Starter $79 a month; Growth $159 and Advanced $279 at 1,000 monthly active contacts (Growth is $239 at 2,500); USD, with a 7-day free trial and no card needed.
• Watch for: broadcasts start on Growth, and WhatsApp fees aren’t included in any plan.

10. 360dialog: API access without a markup

360dialog, which says it is an “Official Meta Solution Partner”, sells API access for developers and software companies.

• Pricing: Regular €49 (or $59) per number per month, Premium €99, plus Meta’s fees with “no markup on Meta fees”.
• Best for: teams building their own tools or plugging WhatsApp into existing software. See ChatMitra vs 360dialog for how the two differ.
• Watch for: you get the API, not a full inbox; that’s an add-on or a partner tool.

11. Twilio: developer platform, per-message fee

Twilio passes Meta’s fee through and adds its own: “Twilio’s per-message fee for WhatsApp is $0.005, inbound or outbound”.

• Pricing: pay as you go, plus $0.001 for each failed message.
• Best for: developers already using Twilio for SMS or voice.
• Watch for: on Sri Lanka’s new $0.002 utility rate, Twilio’s $0.005 fee makes a utility message cost 3.5 times Meta’s price. More in ChatMitra vs Twilio.

12. Infobip: enterprise omnichannel

Infobip describes itself as a “Premier Meta Partner” and publishes all-in Sri Lanka rates in USD.

• Message rates: marketing $0.1012, utility and authentication $0.015322, free-form (service) $0.007264 and international authentication $0.155428.
• Best for: large enterprises that want one vendor for many channels and countries.
• Watch for: marketing is 38% above Meta’s rate, and its utility rate is more than seven times Meta’s new $0.002.

Local or global provider: a decision guide

The OTP trap: authentication-international rates

Most Sri Lankan businesses can skip this section. It matters if you’re based outside Sri Lanka and send one-time passwords to Sri Lankan users: a regional app, a fintech or an airline serving several countries.

Meta’s rules, from its authentication-international rates page:

• The higher rate applies only if your business is based in another country (your primary business location) and Meta has found you eligible.
• You become eligible by sending more than 750,000 messages outside customer service windows in a moving 30-day period to users in countries with authentication-international rates, counted across all your Messaging accounts.
• Meta gives 30 days’ notice by email, and eligibility is permanent.
• You always pay the domestic rate in your own primary business location.

A domestic authentication message to a +94 number costs $0.002; the international rate is $0.144. For 100,000 OTPs a month, that’s $200 against $14,400.

What to do: make sure your Primary Business Location in Meta Business Manager is correct. Foreign businesses should budget OTPs to Sri Lanka at $0.144 past the threshold and compare SMS. See our guide to authentication messages.

Sinhala, Tamil and English: getting templates right

Meta’s list of supported template languages includes Sinhala (si_LK) and Tamil (ta), alongside several English variants. A few rules make multilingual templates work:

• One name, several languages. Create Sinhala, Tamil and English versions of the same message under one name, such as order_shipped. Meta treats each language as a separate template, so each has its own approval status and counts toward your template limit. Meta doesn’t translate anything; you supply every version.
• Choose the language per customer. Store each contact’s preferred language in a contact field rather than guessing from a name.
• Test on real phones, Android and iPhone, before a big send.
• Keep variables at clause boundaries. “Your order {{1}} has shipped” translates cleanly; a variable mid-sentence often doesn’t, because word order differs between the three languages.

Not every template builder offers every code Meta supports, so ask to see the language list during your trial.

Consent and Sri Lanka’s Personal Data Protection Act

Sri Lanka’s Personal Data Protection Act, No. 9 of 2022 is coming into force in stages, on dates set by gazette order under a 2025 amendment. Gazette Extraordinary No. 2498/16 brings sections 2 and 3, Part I (processing of personal data) and Part III (controllers and processors) into operation on 1 January 2027.

Part IV, on “solicited messages”, covers marketing by electronic means, and we found no gazette order bringing it into operation as of 28 September 2026. When it is, section 27 lets a business send such messages “only if a data subject has given consent to receive such messages”. It must also tell people how to opt out free of charge, both when it collects their contact details and in every message, and must disclose who is sending.

You don’t have to wait for the law. WhatsApp’s Business Messaging Policy already requires opt-in permission and requires you to honour every opt-out. Collect opt-ins clearly, record when and where each was given, and give every marketing template an easy way to stop. Our WhatsApp opt-in guide covers the methods. This section is general information, not legal advice.

How to get the WhatsApp Business API in Sri Lanka: 7 steps

1. Create a Meta business portfolio at business.facebook.com with your company’s legal name, address and website.
2. Choose a phone number that can receive an SMS or voice call for verification; a landline works. If it’s on the WhatsApp Business app, ask about coexistence, or remove it from the app first.
3. Connect the number to your provider, through Meta’s Embedded Signup or by sharing your WhatsApp account with the provider.
4. Set a display name that matches your business and website. Meta checks it against its guidelines when your messaging limit rises.
5. Add a payment method in Meta Billing Hub if Meta bills you directly. Without one, service messages stop once the 1,000 free ones are used.
6. Verify your business. New portfolios can message 250 unique people outside the service window per 24 hours. Business verification, or 2,000 high-quality template deliveries to unique users in 30 days, lifts that to 2,000, and Meta scales it from there.
7. Create templates and collect opt-ins. Start with one utility template and one marketing template.

Meta’s reviews take the most time, so start business verification early. More detail in how to get the WhatsApp API.

What to ask every provider before you sign

1. What will I pay Meta, and what will I pay you, as separate lines?
2. Has your Sri Lanka rate sheet been updated for 1 October 2026?
3. Which currency will I be invoiced in, and who pays Meta?
4. How will you bill service messages beyond the 1,000 free?
5. Does your template builder offer Sinhala and Tamil?
6. What support hours cover Sri Lanka time?
7. Is there a minimum term, and can I take my number with me if I leave?

Common mistakes

• Comparing plan prices and ignoring message rates. In our example, Meta’s own charges were the largest part of every total.
• Trusting an old rate table. Several provider pages still show the pre-October utility rate, over five times the new one.
• Sending marketing without opt-in. It breaks WhatsApp’s policy, and blocks and reports hurt your quality rating and limits.
• Labelling everything as marketing. An order-specific confirmation with no promotion can be a utility template at $0.002.
• Using an unofficial bulk sender, which risks a ban. See official vs unofficial bulk WhatsApp senders.

Summary

Sri Lanka’s own rate card, from 1 October 2026, made utility and authentication messages about 82% cheaper, charged service replies at the same $0.002 after 1,000 free, and left marketing at $0.0732. Since marketing is most of a typical bill, choose on three questions: does the provider mark up Meta’s rates, which currency will you pay in, and who supports you in your hours and languages? On published prices, Bloomwire is the cheapest local option; ChatMitra, YCloud and Go4whatsup are the cheapest self-serve platforms; 360dialog, Twilio and Infobip suit developers. Run your own month through the worked example before you commit.
