Okta Client Credentials FLow

See more Okta OAuth/OIDC Examples

The Client Credentials flow is recommended for use in machine-to-machine authentication. Your application will need to securely store its Client ID and Secret and pass those to Okta in exchange for an access token. At a high-level, the flow only has two steps:

• Your application passes its client credentials to your Okta authorization server.
• If the credentials are accurate, Okta responds with an access token.

Note: This example uses "customScope". You'll replace it with whatever scope(s) you've defined for your app. Scopes are defined in your Authorization Server. See Okta Authorization Server / Scopes
