Creator Add Records through API - Workflows not triggered ?

Creator Add Records through API - Workflows not triggered ?

Hi Everyone,

I am trying to add records to my Creator application through a third party app that I am developing. Currently, I am testing this through Postman. 

The records I need to add have a lot of workflows to run to populate dropdowns, fields, use lookups and so on. For example, I need to populate a list of projects from zoho Projects, then when I select the project from this list, another workflow collects other information about this project and fills somes fields. 

The issue: when I create a record through the api, although I did not use the skip_workflow argument, nothing seems to run as I have no other field filled by the workflows.

Any idea how to force them to run ? Or am I doing something wrong ? 

Thanks for the help.
Kind regards,

Guillaume
