The issue: update/adding values to one custom fields removes values to all other previously set custom fields. How do add custom field values without the API clearing all other custom fields? Background: I have created three custom fields that are "dates". These dates represent the dates when the user has taken actions (e.g., "registered" and "subscribed"). API put call to the contacts endpoint https://api.cc.email/v3/contacts/<<contact_id>> with the custom fields JSON in the body does update the contact record, e.g., "custom_fields": [{"custom_field_id": "161d4560-ff1f-11ed-8035-fa163e1233be","value": "5/31/2023"}] However, when a subsequent call to the contacts endpoint to add/update another custom field, does add the custom field value, but it deletes all other custom field values that were previously set. Here is the custom field request, e.g., "custom_fields": [{"custom_field_id": "eb96fd80-4434-11e9-86fd-d4ae529a863c","value": "6/1/2024"}] It's not my code. I confirmed this behavior using the "try" capability in the developer reference: https://developer.constantcontact.com/api_reference/index.html#!/Contacts/putContact
