Compatibility Suite

Switch platforms in minutes, not weeks

API-compatible switching that keeps your existing software, campaigns and workflows intact. Change one API URL and keep shipping.

Zero rework by design

Built for teams moving from another WhatsApp platform without rebuilding integrations.

Keep existing software

Your CRM, store and scripts keep working. Familiar request shapes mean developers change endpoints, not logic.

Keep campaigns running

Templates, contact lists and broadcast flows carry over conceptually, so live campaigns continue without rebuilds.

Change one API URL

Point your integration at G4 Message, drop in a fresh API key, and send your first test message the same day.

Migrate in three steps

1
Connect your number

Link your WhatsApp Business number through the guided setup and verify messaging in the shared inbox.

2
Swap the endpoint

Update the base URL and credentials in your code or integration settings. No payload rewrites needed.

3
Go live and scale

Replay a campaign, confirm delivery reports, then roll the full team onto unlimited numbers and seats.
