Assign time record to project in Everhour

In Everhour, I need to assign a time record to an existing Project.

With the Everhour API (https://everhour.docs.apiary.io/) I am able to retrieve:-information about the time record, as time record id and name-the project id

I do not see a way to connect a project to a time record, or a time record to a project.

Any suggestion?

I am trying to bridge Pipedrive and Everhour leveraging Everhour capabilities by API
