Stdlib.resultRetrieves the IdentityID associated with a DeveloperUserIdentifier or the list of DeveloperUserIdentifier values associated with an IdentityId for an existing identity. Either IdentityID or DeveloperUserIdentifier must not be null. If you supply only one of these values, the other value will be searched in the database and returned as a part of the response. If you supply both, DeveloperUserIdentifier will be matched against IdentityID. If the values are verified against the database, the response returns both values and is the same as the request. Otherwise a ResourceConflictException is thrown.
LookupDeveloperIdentity is intended for low-throughput control plane operations: for example, to enable customer service to locate an identity ID by username. If you are using it for higher-volume operations such as user authentication, your requests are likely to be throttled. GetOpenIdTokenForDeveloperIdentity is a better option for higher-volume operations for user authentication.
You must use AWS Developer credentials to call this API.
