Answer 1

Hard to answer without seeing the code you're using, but the response you send should look like this:

{
 "method": "payments_status_update", 
 "content": {
        "order_id": ORDER_ID, 
        "status": "settled"
        }
}

ORDER_ID should be replaced by the order id sent from fB with the request.

There were incorrect examples out there that showed:

{
 "method": "payments_status_update", 
 "content": [{
        "order_id": ORDER_ID, 
        "status": "settled"
        }]
}

but the second one doesn't work. Check to make sure you're not sending content as an array.
