Thanks for that info! I went ahead and jumped into your portal to take a look at the contact with the vid 2060001, and it appears that they're not currently a member of any workflows. That endpoint will return a blank array if the contact isn't active in any workflows.
There isn’t currently an endpoint to get the contacts enrolled in a workflow, but you can create a smart list of contacts enrolled in a workflow in-app. You can also take the opposite approach and get a contacts current workflow enrollments:
I am trying to get either all contacts in a workflow or all the workflows a contact is present in? I have been hitting Current enrollment | Workflows API of hubspot through postman but not getting any results back. I have the vid of a contact and hubspot api key as well and using basic auth for authorization but I get blank array in response. Also, the response status is 200. Can you help with this please?
