## alte lösung, funzt nicht:

 data = {
        "recipient[id]": recipient_id,
        "message[attachment][type]": "image",
        "message[attachment][payload][]": ""
    }
    items = []

    for name, value in data.items():
        items.append(MultipartParam(name, value))
        
## alte lösung, neuer versuch, funzt auch nicht:
    data = {
        "recipient[id]": str(recipient_id),
        "message[attachment][type]": "image",
        "message[attachment][payload][]": ""
    }
    items = []

    for name, value in data.items():
        items.append(MultipartParam(name, value))
        
## neue lösung, funzt noch nicht:
items.append(MultipartParam("recipient", {"id": recipient_id }))
items.append(MultipartParam("message", {"attachment":{"type":"image", "payload":{}}}))
    
## neue lösung, jetzt funzts wegen str(recipient_id):
items.append(MultipartParam("recipient", {"id": str(recipient_id) }))
items.append(MultipartParam("message", {"attachment":{"type":"image", "payload":{}}}))
