Any business in the World needs to be paid in order to stay in the business. it's in that regard Havanao has developped API that would help you to accept Mobile financing services payment instantanly.
The Havanao API is organized around REST. Our API has predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors. We use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by off-the-shelf HTTP clients. We support cross-origin resource sharing, allowing you to interact securely with our API from a client-side web application (though you should never expose your secret API key in any public website's client-side code).
JSON is returned by all API responses, including errors. To make the API as explorable as possible, accounts have test mode and live mode API keys. There is no "switch" for changing between modes, just use the appropriate key to perform a live or test transaction. Requests made with test mode credentials never hit the live networks.
Note : Our APIs only support Tigo Cash,Airtel Money and Mtn mobile money.
