customSuffix

A string that you provide, which is combined with the service-provided prefix to form the complete role name. If you make multiple requests for the same service, then you must supply a different CustomSuffix for each request. Otherwise the request fails with a duplicate role name error. For example, you could add -1 or -debug to the suffix.

Some services do not support the CustomSuffix parameter. If you provide an optional suffix and the operation fails, try the operation again without the suffix.
