Action Required: HMAC-SHA1 Deprecation for Token-based Authentication (TBA)

edited Jun 2, 2025 2:23PM in Announcements

This notice is intended for customers who use the Token-based authentication (TBA) feature in your account for integrations that use HMAC-SHA1 as a signature method. In NetSuite 2021.2, this method will be deprecated. You must change your integrations to use HMAC-SHA256 as the signature method.

What is Changing?

When your account is upgraded to NetSuite 2021.2, any integrations that are using the Token-based Authentication (TBA) feature with HMAC-SHA1 as a signature method will stop working. This applies to all integrations you create, as well as integrations from the third-party solution providers. The NetSuite 2021.2 release upgrade is targeted to occur between August and October of 2021.

Regards,

@Robert Nedelkow-Oracle | NetSuite Support Community Administrator
