## Request Parameters

**`acs_credential_id`** *String* (Required)

ID of the credential that you want to assign to an access system user.

***

**`acs_user_id`** *String*

ID of the access system user to whom you want to assign a credential. You can only provide one of acs\_user\_id or user\_identity\_id.

***

**`user_identity_id`** *String*

ID of the user identity to whom you want to assign a credential. You can only provide one of acs\_user\_id or user\_identity\_id. If the ACS system contains an ACS user with the same `email_address` or `phone_number` as the user identity that you specify, they are linked, and the credential belongs to the ACS user. If the ACS system does not have a corresponding ACS user, one is created.
