Accepted answer

I'm, trying to update a contact record using the below PUT statement and BODY and I can successfully update the system fields values but I can't update values for a contact's custom text field:



  "emailAddress":"[email protected]",







  "100453":"Bounce reason goes here",


The above body updates the phone number, first name, last name, bounce back status and globally subscribed status but I can't get a custom field which has the ID 100453.

I also tried this but neither option updates in Eloqua:

Howdy, Stranger!
