I have followed the recommended guideline/documentation:
Even though I have generated the token from the enterprise platform successfully, the 42Crunch API Token Type Jenkins Credential setup returns "Invalid format of API Token".
You are using a version of 42Crunch REST API Static Security Testing plugin that is older than 5.2.
Our new format includes "api_" prepending the token.
Please remove "api_" from the token and test again. Our tokens are designed to work both with, and without, the prefix.
Please note that Jenkins plugin version 5.2 accepts the "api_" prefix natively.
