Salesflare new contact issue

I set a new API with Pabbly and Salesflare
but each time I try to make a save & test Request I have this error in return :(

What ever I try If I fill all the required fields
-First Name (Required)
-Last Name (Required)

I'm wonder if the api is accurante?

Thanks for your help
