Hello AndreaL3758,

 

Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.

 

The full format of the error is "custom_fields.{custom field name} is missing". In this instance, the name of the custom field associated with the custom_field_id you provided is "id". Based on the request body you provided it looks like the error is being caused by the “value” property being capitalized in your request when our system is expecting the property in lower case. I am including documentation on the full request which includes a body sample below:

 

PUT (update) a Contact:

Please have a look and let us know if you have any other questions!
