Connect Anything That Can Make a Request

For teams with a developer, an agency, or a system that needs to talk to WhatsApp directly. Send messages, receive webhooks and keep your CRM in sync.

Short answer

The WhatEdge API lets any system send a templated WhatsApp message in a single call, and webhooks push every inbound message, delivery receipt and status change back to you in real time. Use it to connect a CRM, an ERP, a website form or an internal tool.

The problem

Your systems already know when a message should go out

The CRM knows a lead came in. The ERP knows the order shipped. The website knows the form was filled. All of that is a trigger for a WhatsApp message, and all of it currently ends with somebody being told to send one.

What you can do with it

Common uses

These are the setups customers actually ask for. If yours is not here, it is probably still possible — ask.

01
Send from your own application

One API call sends a templated message to any number on your list, with your merge values filled in.

02
Receive incoming messages

A webhook fires on every inbound message, delivery receipt and status change, with retry on failure.

03
Sync your CRM both ways

Push contacts and leads in, pull conversation history and outcomes back out.

04
Trigger from your website

Form submitted, message sent — acknowledgement to the customer, alert to your team.

05
Bulk operations

Create contacts, apply tags and launch campaigns programmatically rather than through the dashboard.

06
Custom internal tools

Anything that can call a URL can now send a WhatsApp message under your verified business identity.

Setup

How it gets connected

Two routes: build it yourself with the API access your plan already includes, or have our team do it as an optional service. The prices are published.

  1. Tell us the use case. What triggers the message, what data it carries, and where the replies should go.
  2. Keys issued. You get API keys with per-key permissions, plus a sandbox to test against safely.
  3. Templates approved. Any message you send first needs an approved template. We handle the wording and the submission.
  4. Integration & testing. Your developer or ours builds it, and we test the full round trip together.
  5. Live with support. We stay available through the first weeks in production.

FAQ

Questions about this integration

Yes, through the API or webhooks. Push contacts and leads in, pull conversation history back out, and fire a message from any system that can make an HTTPS request. We provide keys, documentation, a sandbox and technical support during the integration.

Not for Google Sheets, Tally or Busy — our team sets those up for you. You will want a developer, or our team on a scoped engagement, for custom API work against your own CRM or ERP.

Any message your business sends first — before the customer has written to you — has to use a template that Meta has approved. It stops WhatsApp filling up with unsolicited marketing. WhatEdge handles the writing, category selection, submission and approval tracking, and keeps every approved template ready to reuse. Approval usually takes a few hours.
