How to use

Instantiation

First of all, we must instantiate the SDK.

Keep in mind that the SDK can be instantiated only once, and it is a requirement to be able to use all its methods.

In order to instantiate the SDK we need to specify the public key and the environment.

Retrieving your publicKey

Before instantiating the SDK make sure to retrieve your publicKey. This can be done by: Logging into the Merchant Panel, going into Settings > API Access, under your Read Only Credentials you will find your API Public key.

• npm

import SDK from '@d24/sdk';

new SDK('as1i2nxal12bvd', { environment: 'stg' });

• es

new window.D24.SDK('as1i2nxal12bvd', { environment: 'stg' });
