summary: 'OAuth 2.0 bearer tokens. Every FedEx API request carries an authorization header holding a token obtained from POST https://apis.fedex.com/oauth/token (sandbox: https://apis-sandbox.fedex.com/oauth/token) with the API Key (client_id) and Secret Key (client_secret) issued per project in the Developer Portal. The published OpenAPI fragments model authorization as a required header parameter rather than a securityScheme; the oauth2 scheme in the working specs was added by API Evangelist from this documentation.'
schemes:
- name: oauth2
  type: oauth2
  flow: clientCredentials
  token_url: https://apis.fedex.com/oauth/token
  sandbox_token_url: https://apis-sandbox.fedex.com/oauth/token
  request_content_type: application/x-www-form-urlencoded
  grant_types:
  - client_credentials
  - csp_credentials
  - client_pc_credentials
  credentials:
    client_id: API Key received during FedEx Developer Portal registration
    client_secret: Secret Key received during FedEx Developer Portal registration
    child_Key: Customer Key - login credential for an Integrator, Compatible or Proprietary Parent Child customer (csp_credentials / client_pc_credentials)
    child_secret: Customer Secret paired with child_Key
  token_lifetime: An OAuth token is valid for an hour (Quotas & rate limits guide FAQ)
  header: 'authorization: Bearer <token>'
  scopes: []
  notes:
  - FedEx APIs do not support Cross-Origin Resource Sharing (CORS).
  - 'Best practices: cache the access token until an HTTP 401 is observed, then regenerate; never expose the token to the browser or end user; use TLS 1.2 or higher.'
  - 'Token-endpoint thresholds per public IP: burst 3 hits/second over 5 seconds, average 1 hit/second over 2 minutes; violation returns 403 for 10 minutes (see rate-limits/).'
