    \"public_key\" : \"${PUBLIC_KEY}\", 
    \"order_id\" : \"order_id_1\",
    \"info\" : \"My information\"
}"
# DATA is base64_encode result from JSON string
DATA=$(echo -n ${JSON} | base64)
# SIGNATURE is base64 encode result from sha1 binary hash from concatenate string ${PRIVATE_KEY}${DATA}${PRIVATE_KEY}
SIGNATURE=$(echo -n "${PRIVATE_KEY}${DATA}${PRIVATE_KEY}" | openssl dgst -binary -sha1 | base64)
# REQ is json response from liqpay
REQ=$(curl --silent -XPOST ${API_URL} --data-urlencode data="${DATA}" --data-urlencode signature="${SIGNATURE}")
echo "Result: ${REQ}"
