A list of client IDs (also known as audiences). When a mobile or web app registers with an OpenID Connect provider, they establish a value that identifies the application. (This is the value that's sent as the client_id parameter on OAuth requests.)
You can register multiple client IDs with the same provider. For example, you might have multiple applications that use the same OIDC provider. You cannot register more than 100 client IDs with a single IAM OIDC provider.
There is no defined format for a client ID. The CreateOpenIDConnectProviderRequest action accepts client IDs up to 255 characters long.
