Get Access Token

POST 
/public/auth/v1/access-token

Exchange client credentials for an access token used to authenticate against Payonic services.

Usage

  • Obtain an access token by posting clientId and clientSecret.
  • Use the returned accessToken as a Bearer token in the Authorization header for subsequent requests.
  • The access token can be used across all Payonic services
  • Tokens are valid for 8 hours.

Environments

  • Live clients are prefixed with ext_live_
  • Test clients are prefixed with ext_test_
  • Credentials are distinct per environment; do not mix them.

Client-side rotation

  • Cache and reuse the issued token until it expires.
  • Only request a new token after the previous one has expired to avoid unnecessary token churn.
