I am utilizing Constant Contact's REST API endpoint '/contacts/sign_up_form' to add or update a new contact to a list. Here is my request body:
 
{"email_address":"test@example.com","first_name":"","last_name":"","create_source":"Account","street_address":{"kind":"home","city":"
","state":"","postal_code":""},"list_memberships":["some_list_id"],"custom_fields":[{"custom_field_id":"IPADDRESS","value":null},{"custom_field_id":"LOAN _MOUNT","value":20000.0},{"custom_field_id":"LOAN_REASON","value":"Car loan"},{}]}
 
Then why I am not able to view those custom fields on my account for that contact  ?Is it necessary to create all custom fields in the account before using them in contact creation? What is the exact process of using custom fields? Or is it necessary to create a 'sign_up_form' with required custom fields before using it?

Hello user286192,

 

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.

 

You do need to create the custom fields prior to being able to add data to them. 

 

It looks like you are using the names of the custom fields under "custom_field_id" rather than the actual IDs of the custom fields. 

 

You'd want to make a GET call to /contact_custom_fields in order to get the correct IDs of the custom fields:

 

GET custom_fields Collection

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