# Accept the pending invitation addressed to the signed-in account

> Redeems the newest unexpired pending invitation whose address matches the signed-in account's directory-asserted user principal name or email, creating or reactivating that account's membership with the invited role. The directory itself was verified when the Organization was activated; no invitation token is exchanged. An already active member receives its membership back with 200.

Requires a delegated GV.Access token for a work or school account in the signed-in Microsoft Entra directory; no Organization role is required.

## Authentication and access

* **Required role:** GV.Access
* **Data classification:** metadata
