Sometimes you want to directly share information between two applications without a user getting in the way. For these scenarios, you can use the OAuth 2.0 client credentials flow. In this flow, the client app exchanges its client credentials defined in the connected app—its consumer key and consumer secret—for an access token. This flow eliminates the need for explicit user interaction, though it does require you to specify an integration user to run the integration. You can use this flow as a more secure alternative to the OAuth 2.0 username-password flow.
