Workflow trigger from API

Hi team,
we need to trigger the workflow from API.
last time we tried and got succeed but now not working, can you please give me your support to achieve that features .
sample workflow:- Automation UI Canvas
API end point and URL:-
https://api.hubapi.com/automation/v2/workflows/555202614/enrollments/contacts/praveen.d@valorpaytech.com

Hi there. Thanks for your question. The community nor myself can access your workflow link because it requires access to your portal. Question — is the issue you’re having that you cannot enroll or re-enroll a contact into a specific Workflow using the endpoint — Enroll a contact into a workflow? Can you share the response along with the error code you received, please?

Thank you for the additional details! — Jaycee
