Custom Field in API Request Causing 400 Error

[Raymond Liu]

Hello,

I am trying to set a custom field 11500 with the value "source" for an API call, but I am getting a 400 error.

The documentation states that if a 400 error is return, the user does not have permissions to create custom fields, or the request object properties have invalid or missing values.

I can create custom fields, so I am assuming the property value is invalid? I tried putting in a property that seems to be valid, but now I am getting a connection timed out error.

You should also check the format of your request payload and make sure it follows the API's specifications. Sometimes, a missing or incorrect parameter can also cause a 400 error.
