Hi,
As i said, for now Microsoft Flow does not have ready-to-use connector for Jenkins.
However, you can utilize Rest/HTTP components in Microsoft Flow and utilize Jenkins API to do the integration.
Basically, you can call Jenkins API on a Dynamics 365 trigger or you may schedule it.
You can do this from Jenkins side as well (if you do not want to use Flow), you can use Dynamics 365 Web API to integrate.
If you share a sample scenario, I will give you suggested steps.
Best,
Wahaj
