Backoff Policy

BackOff policy is used to increase the guarantees of receiving a response when fulfilling requests:

• InitialInterval = 500 * time.Millisecond, intervals between repeated requests

• RandomizationFactor = 0.5, Spread of the request on time between retries

• MaxInterval = 60 * time.Second, Maximum time between retries

• MaxElapsedTime = 10 * time.Minute, the time during which the attempts will be made.

Callback by payment system after each transaction

Upon completion of payment, the payment system makes a request to the partner project to transfer the payment status. The request is made to the address specified in the field "callback_url" when initiating the payment.

On receiving an http status other than 200, the transaction will be executed BackOff policy
