invitation resource type

  • Article

Namespace: microsoft.graph

Represents an invitation that is used to add external users to an organization as part of Microsoft Entra business-to-business (Microsoft Entra B2B) collaboration.

The invitation process uses the following flow:

  • An invitation is created.
  • An invitation that contains an invitation link is sent to the invited user.
  • The invited user selects the invitation link, signs in, and redeems the invitation, and the user entity that represents the invited user is created.
  • The user is redirected to a specific page after the redemption completes.

Creating an invitation returns a redemption URL in the response (inviteRedeemUrl). The create invitation API can automatically send an email that contains the redemption URL to the invited user, by setting the sendInvitationMessage to true. You can also customize the message that is sent to the invited user. Instead, if you want to send the redemption URL through some other means, you can set the sendInvitationMessage to false and use the redeem URL from the response to craft your own communication. Currently, no API is available to perform the redemption process. The invited user has to select the inviteRedeemUrl link sent in the communication, and go through the interactive redemption process in a browser. When the process is completed, the invited user becomes an external user in the organization.
