Hey there @DavidTF,

The current API we have allows to modify forms, but only one at a time.

See https://www.typeform.com/developers/create/reference/update-form/ and https://www.typeform.com/developers/create/reference/update-form-patch/. 

Unfortunately there is no way to bulk update forms right now.
Curious about what is the problem you are trying to solve though!

Regards,

Xavi

Exactly like @Xavi explained

To get the list of forms, you can also get forms in a specific workspace or search for forms matching criteria, or just all the forms in your account.

Using the retrieve forms endpoint.

Then you can loop through the forms returned and use the endpoints shared by Xavi.
Keep in mind the partial update only work on certain properties like settings, not to update a specific field.

I have created a Postman collection + flow to describe this too
