From a new workspace to the first WhatsApp conversation.

A practical quickstart for customer onboarding, Meta connection, team setup, API access, and production safety.

Step 1

Create the business workspace

Sign up directly or let a permitted partner provision the organization and its first Business Admin.

Create workspace
Step 2

Connect Meta WhatsApp

Use Embedded Signup to connect the WABA and phone number. Platform Meta credentials remain SuperAdmin-only.

Open channel setup
Step 3

Prepare messaging

Import opted-in contacts, sync templates from Meta, then send a test reply from the shared inbox.

Open setup wizard
Step 4

Secure the integration

Create a scoped API key, verify webhook signatures, rotate secrets, and review delivery logs before production.

Developer workspace
API quickstart

Use scoped keys, never shared passwords.

API keys are tenant-scoped, reveal once, rotatable and auditable. The authenticated Developer page also provides the current OpenAPI 3.0 contract and webhook delivery logs.

  • Contacts, campaigns, conversations and leads
  • Signed webhook delivery with retries
  • Rate limits and mutation audit trails
