How long does onboarding take?

With Convoup's assisted onboarding: typically under an hour for technical setup, plus 1-3 business days for Meta Business Manager verification. Self-service onboarding without assistance may take 1-2 weeks.

Can I use my existing phone number?

Yes, but it must not be linked to a WhatsApp account. If it is, you need to migrate it first (which deletes your WhatsApp chat history on that number).

WhatsApp API Onboarding

Step-by-step guide to getting started with the WhatsApp Business API, from Business Manager setup to first message.

Last reviewed: September 2, 2026•Reviewed by: Convoup Platform & Technical Operations

WhatsApp API onboarding involves five steps: verify your business in Meta Business Manager, create a WhatsApp Business Account, register a phone number, configure a webhook, and send your first message.

Why This Matters

The Problem

The onboarding process involves Meta Business Manager, WhatsApp Business Account setup, phone number registration, webhook configuration, and token generation. For teams unfamiliar with Meta's ecosystem, each step has potential friction points that can delay launch by days or weeks.

Deep Dive

What WhatsApp API Onboarding Actually Is

The fastest path to production is: (1) Verify your business in Meta Business Manager — this takes 1-3 business days if your business documents are in order. (2) Create a WhatsApp Business Account (WABA) and agree to Meta's Commerce Policy. (3) Register a phone number — this must be a number you control, not already linked to a WhatsApp account. (4) Generate an access token (start with a temporary token for testing, then a permanent token for production). (5) Configure a webhook URL to receive inbound messages. (6) Send a test message. Platforms like Convoup handle steps 4-6 for you.

In Practice

Real-World Examples

A business completes onboarding in under an hour using Convoup's assisted onboarding flow — we handle webhook configuration and token management.

A developer takes three days setting up the API manually, encountering issues with Business Manager verification and webhook SSL certificates.

Watch Out

Common Mistakes

Starting without a verified Meta Business Manager account — this is required and takes 1-3 business days.

Using a phone number already linked to a WhatsApp account — you must either migrate it or use a different number.

Skipping the test message step — always send a test before going live to catch configuration issues.
