clientidYOURCLIENTID

clientidYOURCLIENTID is not a standard term but commonly appears as a placeholder in documentation to illustrate where an actual client identifier should be inserted. In OAuth 2.0 and OpenID Connect, a client_id is a public identifier assigned to an application registered with an authorization server or API provider. It identifies the client in requests and responses, allowing the provider to apply policies, consent, and access controls.

The client_id is typically included in the authorization request, often alongside the redirect_uri, response_type, and scope. In token requests it may also be present, depending on the flow. It is not a secret, unlike the client_secret, and it is safe to expose in user agents and logs; however, the security of the application relies on protecting the client_secret (for confidential clients) and using secure channels.

To obtain a client_id, a developer registers an application with the service, providing information such as the application name, redirect URIs, and allowed scopes. Upon approval, the service issues a client_id and, for confidential clients, a client_secret.

The string "clientidYOURCLIENTID" commonly appears in tutorials as a placeholder illustrating where the real client_id should be inserted. In real deployments, replace it with the actual value assigned to your registered application.

Best practices include treating the client_id as an identifier rather than a credential, validating redirect_uris, using PKCE for public clients, and keeping any client_secret confidential.
