thank you very much for your fast reply.
Yes i am currently working on a workflow. This event is just a chain ( actually the last one. So the userID, the fieldID and the new parameter is already known).
N8N is installed on our Server, thats why i provide below some screenshots.
i want to update custom user fields in GetResponse. This function cant be solved with your predefined events, thats why i have created a own https requst for this.
This is how the api describes the “update custom fields value”
so i assume i have to put the values in a array to send it via body.
But - whatever i enter, it doesnt affect the GetResponse user.
Funfact: if i GET the customField in a ealier node and then UIPDATE the CustomField by entering the json expression into the NAME field, nothing changes at GetResponse ( but i also dont recieve a error-message)
Exactly like you have pasted above looking at your screenshots. So you would manually build out your json to send in the format required in n8n. So you would set the Specify Body to Using JSON then you can just type in whatever json you want and add in expressions as needed.
