Getting status and information about payment

How it works?
  1. The company sends a request for payment, with transfer of the server_url.
  2. After processing the operation by processing LiqPay and obtaining the final status, a POST request will be sent to your server with data and signature, where:
  3. data - json string with APIs parameters encoded by the function base64, base64_encode( json_string ),
    signature - is the unique signature of each request base64_encode( sha1( private_key + data + private_key) ),
    base64_encode - returns a string encoded by the base64,
    sha1 - returns the hash as a binary string of 20 characters.
  4. To authenticate a request from a LiqPay server, you must:
  5. - form a signature on the side of your server, using the data received in response from LiqPay and your private_key,
    signature=base64_encode( sha1( private_key + data + private_key) )
    - the final signature must be compared with the received from Callback from LiqPay,
    - if the signature is identical, then you have received a genuine response from the server of LiqPay (not changed by a third party / without the intervention of third parties) and you can fulfill obligations to the customer on payment, in accordance with the received payment status.
  6. To get the current transaction status before receiving the final status in Callback, use the Payment Status API, which you can do at any one time.
Check of the callback of the signature
# SIGNATURE is base64 encode result from sha1 binary hash from concatenate string ${PRIVATE_KEY}${POST_DATA}${PRIVATE_KEY}
SIGNATURE=$(echo -n "${PRIVATE_KEY}${POST_DATA}${PRIVATE_KEY}" | openssl dgst -binary -sha1 | base64)

if [ "x${POST_SIGNATURE}" == "x${SIGNATURE}" ]
echo "ok"
echo "invalid signature: ${POST_SIGNATURE} != ${SIGNATURE}"

# POST_DATA in this example
# base64_post_string

# SIGNATURE in this example
