Authentication
Autotask API user credentials and integration code ApiIntegrationCode: <credential> + Autotask API user credentials and integration code UserName: <credential> + Autotask API user credentials and integration code Secret: <credential> discovered
Autotask API user credentials and integration code compound Get key ↗

Create or use a resource with the API User (API-only) security level, then use that API user's UserName and Secret together with your ApiIntegrationCode. Start from REST API security and authentication; the docs state failed auth happens when the user name, password, and integration key combination is invalid.

Autotask API user credentials and integration code ApiIntegrationCode: <credential> + Autotask API user credentials and integration code UserName: <credential> + Autotask API user credentials and integration code Secret: <credential> + Autotask impersonation resource ID ImpersonationResourceId: <credential> discovered
Autotask impersonation resource ID api_key Get key ↗

If your integration uses impersonation, supply the ImpersonationResourceId header in addition to the normal API credentials. This header is shown as optional in the published REST API Swagger at swagger docs v1.
