# Connection and authentication

Use HTTPS for every request. Plain HTTP access is rejected in normal operation.

Authenticated endpoints support:

• HTTP Basic authentication with an active ODDC username and password

• Windows authentication using Negotiate

HTTP Basic is usually the simpler choice for an unattended integration. A Windows-only ODDC account cannot use HTTP Basic because it does not have an ODDC password. Ask an administrator to create a dedicated active account for the integration.

Every authenticated Regular, Advanced, or Administrator account can use the Integrations API. Do not use a personal administrator account for an automated client.
