1. I have setup Authorize.net as the payment collector. 
2. The contact in Odoo has an active credit card on file

3. The way I create a payment is using json and send a request to Odoo to "create" into 

 "account.payment".

4. Following fields I send - 

"payment_type":"inbound",   "partner_type":"customer",      "partner_id"

  "amount"     "currency_id"   "payment_date"  "communication"  "payment_difference_handling":"open",

"journal_id"   "payment_method_id":3,   "payment_token_id":3,

"partner_bank_account_id":false,   "writeoff_account_id":false

along with the invoice information. 

However, the payment doesn't go through till Authorize.net 
i suspect, i am missing something. 
Any suggestion?
