Machine to Machine OAuth tokens are no longer supported
16 days ago by Don Fogarty
As of April 20 2026, the Tango API will no longer accept machine-to-machine tokens when using OAuth.
On May 14, 2025, the Tango API required new customers to use Client ID, Client Secret, Service Account Username, and Service Account Password to generate the Access Token when using OAuth.
Customers who started using the Tango API before May 14, 2025, were asked in February 2026 to migrate off of machine-to-machine tokens and to use the Access Token flow, and to complete the migration by April 6th, 2026.
