The unique identifier of the attribute source configuration.

Salesforce sources only. The Salesforce record ID. Not used for Coupa sources, which derive the external ID from the request body.

Coupa-specific parameter that determines the refresh flow type.

Denotes the actor of the request. When used, the API will take into account this user's permissions and access. This or x-as-user-id is required when the associated token was produced from the Client Credentials grant or with legacy bearer tokens on select endpoints. A token produced from the Authorization Code grant (which is already scoped to a user) may also use this header to act as a different user in the same company, provided the token carries the identity.users.impersonate scope and the token's own user has been granted the API User Impersonation permission. A request that sends this header without both never acts as the named user; depending on the company's configuration it either proceeds as the token's own user or is rejected with a 403.
