A pingback request typically contains all the information for you to do the product delivery. As an addition, Paymentwall provides a series of reversed parameters as custom pingback parameters for specific needs, you can also add your own parameters as custom pingback parameter in order to implement parameter transmission.

Below is a sample with default format:

http://www.yourserver.com/pingback_path?uid=pwuser&goodsid=gold_membership&slength=&speriod=&type=0&ref=b1493096790&sign_version=2&sig=d94b23ba8585f29978706dd1b153ead9

Refer to pingback types for risk review of Brick payments.

After validating the pingback, your server is always expected to be able to proceed the delivery process and respond to it with only OK in the body of response.
