description: Authentication methods documented for GatewayAPI
schemes:
- type: other
  name: Token
  evidence: The simplest form used for authentication is to just set the Authorization header with the token itself using the Token authorization
    scheme.
  location: header
  header: Authorization
  how_to_obtain: API tokens are generated when creating an account and can be created or revoked from the dashboard.
- type: http-basic
  name: Basic
  evidence: The HTTP Basic authentication scheme is another method supported for backwards compatibility with older integrations.
  location: header
  header: Authorization
  how_to_obtain: Legacy credentials (username and password) are provided in the dashboard under “Developer”, “Credentials”.
- type: apiKey
  name: Legacy query credentials
  evidence: The username is sent as user , and the password as password .
  location: query
  how_to_obtain: Credentials (username and password) are available in the dashboard under “Developer”, “Credentials”.
- type: other
  name: OAuth 1.0a (two‑legged)
  evidence: GatewayAPI supports OAuth 1.0a for legacy integrations. No user interaction is required for the authentication, so this part is skipped
    from OAuth.
  location: header
  header: Authorization
  how_to_obtain: Create an API key (consumer key) in the dashboard; the token and secret are left empty for the two‑legged flow.
note: No OAuth2 flows are documented; only OAuth 1.0a is mentioned.
