I’m testing the REST API Apply tags to contact endpoint here:
I include a contact ID, and then a single tag in the tagIds box. every time I click Try I get the following message: “message”: “Input could not be converted to a valid request”
I’m not really sure what I’m doing wrong. There are only two criteria - contactId and tagIds. I’m not sure why I’m getting the error. I’ve tried with a single tagId and with 2 tagIds (separated by a comma). Both gave me the same error message mentioned above. Any ideas?
