[Production + Sandbox] - V3 - API - Error on signature request activation in the API

This incident has been resolved.

A fix has been implemented and we are monitoring the results.

Since this morning, an error occurs when trying to activate a signature request with the API, in both Production and Sandbox environments.
Our technical team identified that the issue occurs when the header ‘Content-type’: ‘application/json’ is given without any body payload.
As a quick workaround, you can either remove this header, or keep this header and add {} in the body payload.
Our technical team is working on a fix.
