Hello,
I´m currently stuck with an automation for my E-Mail Marketing service. I want to automatically update custom fields and their documentation uses PHP scripts as an example, for which I don´t have any experience.
The link to the documentation: https://support.klicktipp.com/article/389-application-programming-interface-api#api-subscriber-update
I can update the email and the phone without any problems, but I don´t know how to write the webhook, so the custom fields in the array are updatet.
Can anyone help me with that please?
