Getting started with API

API interaction is performed using POST requests in the encoding

UTF-8 to URL https://core.qostiq.com/<API method>

Service accepts JSON requests. When sending, the header must be "Content-Type: application/json". All requests to Qostiq are signed with a secret key from shop settings.

Each method has its own set of mandatory parameters; additional parameters can also be passed, but they do not participate in the formation of the signature.

All responses from the Qostiq service contain attributes result, message, data, error.

If result == true and error_code == 0, then field data contains data that is specific for each request. If result == false, then error != 0 — request was processed with an error, data = None, field message contains the description of the error; also by the error code (error) it is possible to find more detailed information.

To start working with Qostiq service via API, you need to register an account https://business.qostiq.com/auth/register and create a shop https://business.qostiq.com/shops/create, on whose behalf requests shall be sent.

Warning! Each shop has its own balance in each currency and is not related to the balance of the personal wallet.
