var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var http = new CkHttp();

// Implements the following CURL command:

// curl --request POST 'https://api.sandbox.paynow.pl/v1/payments' \
// -H 'Content-Type: application/json' \
// -H 'Api-Key: c12c386b-650b-43db-9430-d84fc05d9433' \
// -H 'Signature: aYPCytCoc+/wFgqHZJjgBCi20omXTn0yzm9LysJgnFo=' \
// -H 'Idempotency-Key: 59c6dd26-f905-487b-96c9-fd1d2bd76885' \
// --data-raw '{
//     "amount": 45671,
