Message Summary

Connectors support in Microsoft Teams is transitioning to a new webhook URL format to enhance security. In the future, connector webhook URLs will contain the name of the tenant in them.

Old URLs continue to work for now, but users will be prompted to re-create connectors.

When this will happen

We will begin transitioning to the new webhook URLs on Monday January 11, 2021; however, existing webhooks URLs will continue to work for three (3) months to allow for migration time.

What this means for your organization

Users who have configured connectors will need to undertake one of the following actions, depending on the type of connector:

  • Recreate the connection by removing and then re-configuring the connector
  • For incoming webhooks, first tap the Update URL button. Then copy-paste the new URL to the third party source that is consuming the URL.
