Create invitation
Namespace: microsoft.graph
Important
APIs under the /beta
version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.
Create a new invitation or reset the redemption status for a guest user who already redeemed their invitation. The invitation adds the external user to the organization as part of B2B collaboration. B2B collaboration is supported in both Microsoft Entra External ID in workforce and external tenants.
The following options are available for creating an invitation:
- On invitation creation, Microsoft Graph can automatically send an invitation email directly to the invited user, or your app can use the inviteRedeemUrl returned in the response to craft your own invitation (through your communication mechanism of choice) to the invited user. If you decide to have Microsoft Graph send an invitation email automatically, you can specify the content and language of the email by using invitedUserMessageInfo.
- When the user is invited, a user entity (of userType
Guest
) is created and can be used to control access to resources. The invited user has to go through the redemption process to access any resources they have been invited to.
This API is available in the following national cloud deployments.

Permissions
Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Important
In delegated scenarios with work or school accounts, the signed-in user must be assigned a supported Microsoft Entra role or a custom role with a supported role permission. The following least privileged roles are supported for this operation:
- To invite guests:
- Both nonadmin member users and guest users can invite guests if the tenant admin hasn't restricted the default user permissions.
- Guest Inviter, Directory Writers, or User Administrator.
- To reset the redemption status: Helpdesk Administrator or User Administrator.
- Application permissions (app-only) don't work if B2B invitations are disabled on the tenant or if B2B invitations are restricted to administrators.
- When resetting the redemption status for a guest user, the User.ReadWrite.All permission is the least privileged permission for the operation.
