A WhatsApp marketing API is a programmable connection to Meta's business messaging platform that lets your own systems trigger campaigns and read replies. WappBlaster is WhatsApp marketing software and a WhatsApp marketing API on Meta’s official Cloud API. One platform, two doors. Marketers get campaigns, chatbot, shared inbox and templates in a dashboard. Developers get the REST API and signed webhooks that drive the same account from their own stack.

}WhatsApp marketing API in brief
WhatsApp marketing API access at WappBlaster comes with the campaign software attached, so one licence serves both the marketing desk and the engineering team on Meta's official Cloud API. Developers get scoped, rotatable REST keys for sending templates, starting conversations and managing contacts, plus webhooks that push every delivery, read, reply, button click, opt-out and failure to your endpoint, retried and signed for verification. Marketers keep a no-code composer, timezone scheduling, an AI chatbot that passes tricky threads to a person, and a shared inbox on the same number. One flat ₹7999 yearly fee applies in India ($200 abroad), and neither contact count nor API volume is capped, while Meta adds its own per-message rate on top, passed through at cost. Teams leaving another provider usually finish in 1-2 working days: templates are rebuilt and approved in parallel, the number moves during a single maintenance window, and contacts, chat history and flows come across with it. Quality rating alerts warn before a drop limits sending.
A WhatsApp marketing API lets your software send campaigns, manage contacts and templates, and receive delivery and reply events over Meta's official WhatsApp Business Platform.
WappBlaster pairs that API with a full marketing dashboard under one licence costing ₹7999 ($200) yearly, flat, and API traffic is never metered or charged per call.
Nobody re-buys anything when the developers start using the account.
Every delivery, read and reply event reaches your stack verifiably.
Heavy integration traffic does not raise the bill.
CRM, Shopify, WooCommerce and Zoho connections come out of the box.
The WhatsApp Business API is Meta's programmatic channel for sending and receiving WhatsApp messages at scale, without a phone app. WappBlaster provides access to it with a REST API, signed webhooks, an AI chatbot, a shared inbox and template management. Migration from another provider takes one to two working days.
Both, on one licence. Marketers use the WhatsApp marketing software: a campaign composer, segmentation, scheduling, an AI chatbot and a shared inbox, no code involved. Developers use the WhatsApp marketing API: REST endpoints and signed webhooks driving the same account. One flat fee covers both.

Some of the businesses using WappBlaster products every day
One platform, two doors
The same WhatsApp number, templates and history behind both. Nobody re-buys anything when the other team starts using it.
Everything runs from the dashboard. No developer needed to send a campaign.
The same account, driven programmatically from any service you run.
Why teams migrate
Collected from migration calls. If three of these are true for you, the switch usually pays for itself inside a quarter.
Per-user and per-message charges stack on top of Meta. Growth raises the invoice before it raises a single reply rate.
You get branching menus, but no genuine intent matching, no graceful fallback, and a handover to a human that loses the conversation history.
Rejections arrive without a reason, tickets sit for days, and a campaign that was ready on Monday is still waiting on Thursday.
A knowledge base and a support bot. Nobody sits with you while you register the number, write the first templates and wire the first webhook.
The pre-built CRM connector works. Anything custom becomes a paid add-on, a partner referral, or a polite no.
Exporting contacts and chat history, or moving a verified number to another provider, is made harder than it needs to be.
Platform
No per-call pricing and no paid add-on for custom endpoints.
Send templates, start conversations and manage contacts from your own backend in any language. Keys are scoped and rotatable.
Delivered, read, replied, button-clicked, opted-out and failed, POSTed to your endpoint with retry and signature verification.
Intent matching answers the routine questions and escalates the rest to a human, carrying the full thread across so nothing is re-asked.
Assignment, internal notes, tags and resolution states, so several team members work one number without stepping on each other.
Draft, submit, track approval state and version templates from the dashboard, with rejection reasons surfaced rather than buried.
Watch your number quality and messaging tier, with alerts before a rating drop starts limiting how much you can send.
Switching provider
Your current provider stays live until the last step. The only interruption is the window when the number is released and re-registered.
We list the templates, flows, integrations and contact fields you have today, and flag what will not carry over unchanged.
Templates are recreated and submitted for approval on our side while your existing provider keeps running. Nothing is switched yet.
The number is released and re-registered, usually inside one maintenance window. Chat history and contact lists come across with it.
We send test traffic through every template and webhook, confirm delivery events land in your systems, then train the team.
What migration involves
Connects to
Order, shipping, COD confirmation and abandoned cart events, mapped to templates.
Two-way contact and stage sync, with WhatsApp threads written back to the record.
For the systems without a native connector, without writing a service yourself.
Facebook lead ads, Google Forms and site forms drop straight into a tagged segment.
Point webhooks anywhere and call the REST API from your own service. No add-on fee.
Route incoming messages to your LLM or intent service and post the reply back through the API.
Policy
Deliverability on WhatsApp is a compliance problem before it is a marketing one. A number with a poor quality rating cannot send, whatever you paid.
₹7999 per year in India, $200 internationally, whether you run it as WhatsApp marketing software from the dashboard or drive it through the API. Unlimited contacts, unlimited API calls; Meta bills per message separately, at cost. The full breakdown, including how Meta's rate card works, lives on the sender page.

Yes. WappBlaster registers your number on Meta’s WhatsApp Business Platform under a verified business profile, with templates Meta reviews. It is the same underlying channel used by every legitimate provider, not an unofficial automation layer.
Link to this answerBoth, on the same licence. The WhatsApp marketing software is the dashboard: campaign composer, segmentation, scheduling, AI chatbot and shared inbox, usable with no code. The WhatsApp marketing API is the REST interface and signed webhooks that drive the same account programmatically. Most teams start in the dashboard and add the API later; nothing is re-bought either way.
Link to this answerFor teams that want the official Meta Cloud API without per-user seats or markups on Meta’s rates, the best WhatsApp marketing API provider in India is WappBlaster. The licence is a flat ₹7999 ($200) a year and includes the REST API, signed webhooks, AI chatbot, shared inbox and template approval help, and an existing number moves over from any BSP in one to two working days.
Link to this answerSend approved templates, start and continue conversations, create and update contacts, manage tags and segments, and read campaign results. Authentication uses scoped keys you can rotate, and every endpoint is rate-limit aware.
Link to this answerDelivered, read, replied, button-clicked, opted-out and failed. Each is POSTed to your endpoint with a signature you can verify, and retried with backoff if your service is briefly unavailable.
Link to this answerYes. We audit your current templates, flows and integrations, rebuild them on our side while your existing provider keeps running, then move the number in a single maintenance window. Chat history and contacts come across.
Link to this answerOne to two working days for most accounts. The preparation happens in parallel with your current provider still live, so the only interruption is the short window when the number is released and re-registered.
Link to this answerIt escalates rather than looping. The conversation moves to a human in the shared inbox with the full thread attached, so the customer is not asked to repeat themselves and the person replying has context.
Link to this answerYes. Route inbound messages to your own LLM or intent service through a webhook, then post the response back via the REST API. There is no requirement to use our built-in replies.
Link to this answerNo. The platform fee is flat and covers unlimited API calls within fair-use rate limits. Meta’s per-message charge is separate and passed through at cost.
Link to this answerYou get alerted before it starts limiting throughput. We then review which templates are drawing blocks or reports, adjust categorisation and targeting, and rebuild the rating deliberately rather than waiting it out.
Link to this answerThe API works globally. Our strongest support presence is India, UAE, USA, UK, Canada, Australia and Singapore. Meta’s per-message rate varies by the recipient’s country, and we show that before you send.

Ask a real person. We reply on WhatsApp, usually within the hour.
Templates, flows, integrations, whatever you have. We will come back with a migration plan that says what carries over unchanged, what needs rebuilding, and how long the window is.
