Marketing dashboard · REST API · No per-call fee

WhatsApp Marketing API, with the marketing software built in

One platform, two doors. Marketers get real WhatsApp marketing software: 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.

The pain

Per-agent fees, metered API calls and a markup hidden in "credits"

The fix

One flat platform fee, unlimited calls and agents, Meta billed at cost

What is the WhatsApp Business API?

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.

Is this WhatsApp marketing software or a WhatsApp marketing API?

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

Marketing software for the team, marketing API for the stack

The same WhatsApp number, templates and history behind both. Nobody re-buys anything when the other team starts using it.

For marketers: WhatsApp marketing software

Everything runs from the dashboard. No developer needed to send a campaign.

  • Campaign composer with approved templates, rich media and buttons
  • Segmentation and scheduling, including by recipient timezone
  • Delivered, read, replied and clicked, reported per template
  • AI chatbot answers replies; a shared inbox holds the conversations

For developers: WhatsApp marketing API

The same account, driven programmatically from any service you run.

  • REST API for sending, contacts and template management
  • Signed webhooks for every delivery, read and reply event
  • No per-call fee and no metering on API traffic
  • CRM, Shopify, WooCommerce and Zoho hooks out of the box

Why teams migrate

What people tell us about their current BSP

Collected from migration calls. If three of these are true for you, the switch usually pays for itself inside a quarter.

Bills that scale faster than campaigns

Per-agent and per-message charges stack on top of Meta. Adding a support rep raises the invoice before it raises a single reply rate.

A flow editor pretending to be AI

You get branching menus, but no genuine intent matching, no graceful fallback, and a handover to a human that loses the conversation history.

Template approvals that stall

Rejections arrive without a reason, tickets sit for days, and a campaign that was ready on Monday is still waiting on Thursday.

Documentation instead of onboarding

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.

Integrations only where the vendor built them

The pre-built CRM connector works. Anything custom becomes a paid add-on, a partner referral, or a polite no.

Deliberate exit friction

Exporting contacts and chat history, or moving a verified number to another provider, is made harder than it needs to be.

Platform

What you get to build against

No per-call pricing and no paid add-on for custom endpoints.

REST API

Send templates, start conversations and manage contacts from your own backend in any language. Keys are scoped and rotatable.

Webhooks for every event

Delivered, read, replied, button-clicked, opted-out and failed, POSTed to your endpoint with retry and signature verification.

AI replies with handover

Intent matching answers the routine questions and escalates the rest to a human, carrying the full thread across so nothing is re-asked.

Shared team inbox

Assignment, internal notes, tags and resolution states, so several agents work one number without stepping on each other.

Template management

Draft, submit, track approval state and version templates from the dashboard, with rejection reasons surfaced rather than buried.

Quality rating monitoring

Watch your number quality and messaging tier, with alerts before a rating drop starts limiting how much you can send.

Switching provider

How a migration actually runs

Your current provider stays live until the last step. The only interruption is the window when the number is released and re-registered.

  1. 1

    Audit the current setup

    We list the templates, flows, integrations and contact fields you have today, and flag what will not carry over unchanged.

  2. 2

    Prepare in parallel

    Templates are recreated and submitted for approval on our side while your existing provider keeps running. Nothing is switched yet.

  3. 3

    Move the number

    The number is released and re-registered, usually inside one maintenance window. Chat history and contact lists come across with it.

  4. 4

    Verify and hand over

    We send test traffic through every template and webhook, confirm delivery events land in your systems, then train the team.

Policy

Staying inside the rules

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.

  • Opt-in capture through website forms, links and click-to-WhatsApp ads
  • Correct template categorisation across marketing, utility and authentication
  • Per-message cost visibility, matching how Meta has billed since July 2025
  • Quality rating monitoring and template strategy to protect your tier
  • Unsubscribe and preference handling wired into every campaign
  • Aligned with Meta’s WhatsApp Business Platform policies and India’s DPDP rules

Same flat fee, whichever door you use

₹7,999 per year in India, $200 internationally, whether you run it as WhatsApp marketing software from the dashboard or drive it through the API. Unlimited agents, 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.

Frequently asked questions

Is this the official WhatsApp Business API?

Yes. Your number is registered 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 answer
Is this WhatsApp marketing software or an API?

Both, 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 answer
What does the REST API actually let me do?

Send 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 answer
Which webhook events do you send?

Delivered, 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 answer
Can I migrate my existing WhatsApp number?

Yes. 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 answer
How long does migration take?

One 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 answer
How does the chatbot handle things it does not understand?

It 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 agent has context.

Link to this answer
Can I use my own AI model instead of yours?

Yes. 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 answer
Do you charge per agent or per API call?

Neither. The platform fee is flat and covers unlimited agents and unlimited API calls within fair-use rate limits. Meta’s per-message charge is separate and passed through at cost.

Link to this answer
What happens if my quality rating drops?

You 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 answer
Which countries do you serve?

The 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.
