IPN Notification Payload

After you enable IPN Notifications for your products and have successfully setup IPN Notifications on your website, you will receive a post request every time a buyer has purchased a product and paid for the product in its entirety.

To verify the integrity of the payload, we will send an HMAC signature over a HTTP header called "IPN_HASH". The HMAC signature will be a signed json encoded POST object with your IPN secret. You can see how to verify the signature in the example_rocketr_ipn.php file in this repository.

We will send the following information in the post request as a JSON Object:

• order_id
  • This is a unique string of 12 characters that identifies each order.
• product_title
  • This the product title for which the IPN is being sent.
• product_id
  • This the product id for which the IPN is being sent.
• buyer_email
  • The email address of the buyer.
• buyer_ip
  • The IP Address of the buyer (note this can be in IPv4 or IPv6 format)
• payment_method
  • This is a number that represents the payment method used for the purchase:
    • 0 = Paypal
    • 1 = Bitcoin
    • 2 = Ethereum
    • 3 = Perfect Money
    • 4 = Stripe
• invoice_amount_usd
  • This is a decimal value of the amount the buyer was invoiced (and the amount the buyer paid in USD)
• quantity
  • The number of items the buyer purchased.
• purchased_at
  • A MySQL DateTime object signifying the time the invoice was generated (formatted as Y-m-d H:i:s)
• txn_id
  • This is a string that represents a transaction id for the payment method used to purchase the product. For example, this can refer to payapl's transaction id, btc/eth's blockchain ID, or perfect money id
• status
  • This is an integer value that refers to the order status. Please see sample code for more information.
• custom_fields
  • This contains all the custom fields that may have been associated with the order.
  • You can use custom fields to, for example, ask the buyer for their account username/id/email associated with an account on your website
