Hello,

I have been spinning my wheels on how to create a custom field on a Contact record type via the REST API using the PHP SDK. Might someone be willing to share an example of how it is done?

Thanks!

Custom Fields need to be added through the Admin setup of the Infusionsoft Application. Once you have them configured, you can manipulate the data via the custom\_fields array of the Contact object.
