Hi, I’m trying to get a Brevo Add Contact module to work but I keep getting a 400 error that says Transactional attribute as primary Key is missing (invalid_parameter).
I’m not sure why it wants a Transactional attribute as it’s the Contact attributes that are being added.
Only thing I can see in the Brevo documentation is that the attribute’s parameter should be passed in capital letter while creating a contact. eg: {“FNAME”:“Elly”, “LNAME”:“Roger”, “COUNTRIES”:[“India”,“China”]}
The Make module sends it as lower case. But no idea if this is even the issue. I’ve tried using a HTTP POST instead of the Brevo module but I also can’t get it to work.
Any help, greatly appreciated
