OAuth2 Authenticator (Client Credentials)

This node supports the client credentials grant flow. The target audience of this node are users with a technical understanding of OAuth 2 and (web) developers. For less technical users, it may be simpler to use service-specific nodes, such as Microsoft Authenticator or Google Authenticator.

The client credentials grant is used to obtain an access token on behalf of an application/client, without having the context of a user.

Options

Token endpoint URL: The token endpoint URL of the OAuth2 service.
Token endpoint request method: HTTP method to use when requesting the access token from the token endpoint.
Client/App authentication mechanism: How to transfer Client/App ID and secret to the service endpoints. HTTP Basic Auth is the most common mechanism, but some services expect these values to be part of the form-encoded request body.
Client/App ID and secret (flow variable): Specifies the credentials flow variable with the client/app ID and secret to use.
Scopes: The list of scopes to request for the access token.
Additional request fields: Allows to add request body fields (key and value) to the token endpoint request.
