Terms and Abbreviation

Merchant – the owner of an online store.
Buyer – an individual or a company who pays for goods or services.
Transaction – order or transfer of funds for goods or services received by a merchant from a customer.
Token – a secret string used by the system to identify the merchant and the web-site through which the transaction is registered.

API Reference

Lovat API uses the REST architecture. The API has predictable, resource-oriented URLs and uses HTTP response codes to indicate API errors. The API always responds in the JSON format, including cases of errors.

Authentication

Authentication to the Tax rate API is performed via HTTP header basic authentication. Subscribers need to provide a token as the basic authentication value. If you’re new to Lovat, you’ll need to sign up for an account to get your API key. The API uses built-in HTTP features such as HTTP authentication and HTTP verbs, which can be interpreted by off-the-shelf HTTP clients. It also supports cross-origin resource sharing, allowing you to access it securely from a client web application.
