Paste four Meta values. Watahub keeps the business token.

Four Meta values on the gateway. Once.

1. App ID META_APP_ID

   Meta app that owns the webhook.

2. App Secret META_APP_SECRET

   Exchanges the code. Callers cannot send it.

3. Configuration ID META_CONFIGURATION_ID

   Embedded Signup config_id for FB.login.

4. API version META_API_VERSION

   Graph version. Default v24.0.

1. Connect the line

   Send the code, the WABA id, the phone number id, and the PIN. The gateway finishes the line.

2. Send

   Name that phone number id. Watahub uses the stored token. You do not pass it.

curl -X POST "$GATEWAY/v1/onboarding/connect" \
  -H "Authorization: Bearer $WATAHUB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "code": "AQD...embedded-signup-code",
    "wabaId": "105555123456789",
    "phoneNumberId": "100609346426000",
    "pin": "581063"
  }'

{
  "phoneNumberId": "100609346426000",
  "wabaId": "105555123456789",
  "subscribed": true,
  "registered": true
}

curl -X POST "$GATEWAY/v1/messages" \
  -H "Authorization: Bearer $WATAHUB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "+15551234567",
    "phoneNumberId": "100609346426000",
    "kind": "text",
    "text": { "body": "Hello from Watahub" }
  }'

• System user token

  Connect stores a business token for that phone number id.

• Manual WABA subscribe

  Connect subscribes the WABA to messages.

• Manual phone register

  Connect registers the phone with the 6-digit PIN.

• Cloudflare Workers

  The gateway is its own Worker. This page is not that Worker.

• Node

  Same routes. pnpm run dev:node.

• One subscriber webhook

  Meta posts to /webhook. You get one signed, normalized delivery.
