Retrieves 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.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginLookupDeveloperIdentity and EndLookupDeveloperIdentity.
