API V3 updating a contact's birthday fails with error

frankebailey at April 25th, 2018 06:13 — #1

Hi folks, I'm doing an update via the API as follows:

{
  "custom_fields":
    {
      "custom_field":{
          "id":"5a6b0c0aaa7620bd07dfe0e1"
        },
    "value":"31/01/1972"
  }
}

That ID is a custom field for the user's Birthday.

I get the following response:

[status] => 400
[message] => Invalid request data
[error_name] => invalid_request_data
[error_message] => A validation error has occurred
[errors] => 
  (
     [custom_fields] => Must be an array  
  )

As far as I can tell, custom_fields IS an array, so can anyone possibly tell me what I'm doing wrong please?

Thanks!

From what I see you are sending single JSON object not an array in here

Hi Pawel,

Thanks for the quick response! You were 100% right, I'd missed out the parent array. When I added that in it began to work.

You guys rock!
