创建帐单计划因Malformed_Request错误

Question

I am trying to create a billing plan with the request below. (It's valid JSON) and I've checked the request and seems to be correct based on the example requests given on PayPal's (Irrespective of this, I've tried using the stock example and It wont work.

    "auto_bill_amount": "YES",
    "initial_fail_amount_action": "CONTINUE",
    "max_fail_attempts": "12"

{"name":"MALFORMED_REQUEST","message":"Incoming JSON request does not map to API     request","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST","debug_id":"8437249fdc6d1"}

As far as I can see the request is correct, I'm authenticating, I've got the correct URL, anyone spot what the problem is?

Answer 1

You have autobill_amount and it should be auto_bill_amount . You also have initial_amount_fail_action and it should be initial_fail_amount_action .

Answer 2

Right, It was my error not setting the cycles to 0, as this is a continuing payment until someone cancels it, it should be 0 not 12.

So, Corrected request (Which works)
