Thanks @Victor for the info and the for submitting the ticket to Integromat/Make.
I cheched again using Postman and the “HTTP module” in Integromat.
Here what I found:
- ADDING records: I’m not able to do it to the User collection, but I can to any other collection
- UPDATING records: this is working well without restrictions of collection or tool
In summary, the Users collections is clearly restricted for “adding”, so I’m planning on opening a ticket with Adalo support to confirm that is in fact the case. Hopefully will post again here any input from them.
