How to update Custom Fields

[SAPSupport]

Dear teams.

Please let me know how to update CustomFields.

I want to update the data in the contact's CustomFields from the screen. I couldn't find a way to do that. I also researched the API on the help page below, but couldn't find a way.

Dear Customer,

First of all, you need to activate the API usage in the "Odata APIs" tab of the custom fields.
You can activate the usage for Contact API Version 3 or Version 4.

Secondly, you can use the metadata the check the attribute name of your custom fields.

At last, you can put the custom fields into the payload of ContactOriginData to update the contact master data with custom field.
