How can I send the value of a custom field via POST?

[LSchwenk]

I want to achieve the following:

I have a customfield in my card and I want to add a card button which can send the value of the custom field via post request to my backend.

Already tried to send the custom field via payload.

Your payload should look something like

{ “some text” : “{{%customfieldname}}”}
