HMAC-SHA1 Deprecation for Integrations Using Token-based Authentication (TBA)

Hello Team,

We use integration with NetSuite and we receive the following notification:

24-hour Test Window for HMAC-SHA1 Deprecation for Integrations Using Token-based Authentication (TBA)

You are receiving this notification because you use the Token-based Authentication (TBA) feature in your account for integrations that use HMAC-SHA1 as a signature method. As of NetSuite 2021.2, the use of HMAC-SHA1 will be deprecated. Before your account is upgraded to 2021.2, 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 use the Token-based Authentication (TBA) feature with HMAC-SHA1 as a signature method will stop working. This limitation applies to all integrations in your account, including integrations from third-party solution providers. Upgrades to NetSuite 2021.2 are targeted to occur between August and October of 2021.
