Add an attribute to an external identities self-service sign up user flow that's represented by an externalUsersSelfServiceSignupEventsFlow object. You can add both custom and built-in attributes to a user flow.
The attribute is added to both the attributeCollection> attributes and attributeCollection> attributeCollectionPage > views collections on the user flow. In the views collection, the attribute is assigned the default settings. You can PATCH the user flow to customize the settings of the attribute on the views object, for example, marking it as required or updating the allowed input types.

HTTP request
POST /identity/authenticationEventsFlows/{authenticationEventsFlow-id}/microsoft.graph.externalUsersSelfServiceSignUpEventsFlow/onAttributeCollection/microsoft.graph.onAttributeCollectionExternalUsersSelfServiceSignUp/attributes/$ref
In the request body, supply an odata.id property with the ID of the identityUserFlowAttribute object to add to the user flow.
Response
If successful, this method returns a 204 No Content response code. If unsuccessful, a 4xx error is returned with specific details.
Examples
Request
The following example shows a request that adds city as an attribute for attribute collection step of an external identities self-service sign-up user flow. If the request is successful, the attribute is added to both the attributeCollection> attributes and attributeCollection> attributeCollectionPage > views collections on the user flow. After adding the attribute to the user flow, you can PATCH the user flow to customize the settings of the attribute on the views object, that is, customize the page layout.
