Hi @capricorn ,
I tested on my side, and indeed you can’t change a category field to a text one.
And I don’t think the API can be dynamic like what you proposed either.
But, I just got an idea about how you could proceed:
- let’s say your category field is called CF
- create a new text field, for example TF
- download all your contacts
- copy what is inside CF to TF
- import your contacts again to Brevo, and update TF with the data you just copied in this field
=> then you can remove CF and use TF
What do you think? I understand this would require a bit of effort on your side, but at least the migration would be « easy » to do
