API Security Protocol
All API requests must be authenticated with a key in the request. Your API keys carry many privileges, so be sure to keep them secret!
You authenticate to the NOWPAY API by providing your key and username for each request.
What is KEY?
Key is a self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is managed by Nowpay as 256 char bit encoded format.
All the requests with nowpay will be matched with key provided and configured at server side.
