Sinch Engage uses Meta's embedded signup tool to handle your onboarding process, cutting lead time from days to minutes. In the four-step signup flow, you can manage business accounts for both Meta and WhatsApp, manage WhatsApp Business Profiles, and complete required verification steps.


Only admins have the permissions to connect channels in Sinch Engage.


Before connecting WhatsApp, you must have:

  1. A phone number that can receive international SMS or phone calls and is not connected to any WhatsApp account.
  2. Access to a Facebook account that has been added to the Meta Business Suite for your business with admin rights.
    Go to Meta Business Suiteopen-external-link-icon.png

    To learn more about Meta entities and the requirements consult our FAQ WhatsApp onboarding.

    If your business doesn't have Meta Business Suite then you only need a Facebook account.

Key points:

  • For fast and easy onboarding, make sure to:
    • Add accurate and relevant details to your Business Profile.
    • Fill in matching information on Sinch Engage and in the Meta embedded signup if you're creating a new Meta Business Account and/or a new WhatsApp Business Account.
    • Fill in information that matches your previously created account on Sinch Engage if you're using an existing Meta Business Account and/or an existing WhatsApp Business Account.
  • The Connect WhatsApp flow has a Save & exit feature which enables you to quit the flow and resume it later without loosing your current progress.
