Client credentials flow
An OAuth flow where a server-side application authenticates directly using its client ID and secret without a user logging in. Used in automation workflows that run in the background without human interaction.
Expert insight
The client credentials OAuth flow is meant for server-to-server authentication with no human user involved, using it where a delegated user-authorization flow is actually appropriate (like accessing a specific user's data) grants the automation broader access than it needs, a common over-permissioning mistake.
In a real workflow
A server-to-server integration authenticates with a client ID and secret to get a token, with no user involved.
Common mistakes
- Using this flow for actions that should be tied to a specific user.
- Storing the client secret in plain text.
