TvxAuthType

TvxAuthType = (fatNone, fatBasic, fatBearer, fatMicrosoftOAuth, fatGoogleOAuth, fatNetsuiteOAuth, fatCustomOAuth, fatWindows)

Example​

procedure ConfigureBearer(Client: TvxHTTP; const Token: String);
begin
  Client.AuthType := fatBearer;
  Client.Password := Token;
end;

Usage​

TvxAuthType selects no authentication, Basic, bearer, provider OAuth, custom OAuth or Windows SSPI for Velox HTTP and transport clients.

Members​

ValueOrdinalMeaning
fatNone0Disable the local authentication callbacks and clear request credentials.
fatBasic1Use HTTP Basic authentication with Username and Password.
fatBearer2Use Velox's bearer handler; current TvxHTTP supplies Password as the bearer token.
fatMicrosoftOAuth3Acquire/use a Microsoft OAuth token through the Velox OAuth authenticator.
fatGoogleOAuth4Acquire/use a Google OAuth token.
fatNetsuiteOAuth5Acquire/use a NetSuite OAuth token, including its provider-specific client-assertion path.
fatCustomOAuth6Use caller-supplied OAuth endpoints and settings.
fatWindows7Use Windows SSPI/NTLM authentication and optional Domain.

Behavior and boundaries​

  • fatBasic sends a reversible base64 credential representation and is safe only over authenticated TLS.
  • fatBearer does not obtain a token; the current client passes Password to the bearer authentication object. Protect that property as a secret.
  • Provider/custom OAuth members select bearer authentication but first call TvxOAuth2Authenticator; required Tenant, ClientId, Secret, Scope, endpoints and GrantType vary.
  • fatWindows selects TIdSSPINTLMAuthentication. The Velox legacy fatNTLM is normalized to fatWindows in some product copy paths but is not script-visible.
  • When InProcessAuth is false, Velox pre-creates authentication so credentials can go with the first request; when true, challenge handling controls the exchange.
  • Authentication selection does not configure TLS. Set and verify transport security separately.

Additional Technical Info​

TvxAuthType selects the authentication handler used by TvxHTTP and related transports. The meaning of credential properties depends on the selected member.

The product's native enum contains a ninth trailing member, fatNTLM, labelled old. The PascalScript importer deliberately/accidentally stops at fatWindows; scripts cannot name fatNTLM. Shared members keep the same ordinals because the omission is trailing.
