Installation

Load D24 as a npm module

Install the D24.js from the npm public registry.

npm install @d24/sdk

or

Manually load the D24.js script

Add the D24.js module as a script in the top of your app HTML

<script
	type="module"
	src="https://d24sdk.s3.amazonaws.com/releases/d24-1.0.21.es.js"
></script>

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' });

How to use the constructor SDK(publicKey, options)

Required parameters

Parameter	Type	Description	Required	Possible values
publicKey	string	Public key provided by D24	true	-
options	object	Options	true	-
options.environment	string	Environment	true	stg, prod

Possible errors

Error	Explanation
SDK was already instantiated.	The SDK has already been instantiated and you are trying to instantiate it again
The environment [config.environment] is not supported.	The environment you passed to the constructor is not valid, remember that it only accepts "stg" or "prod"
You must instantiate D24CreditCardSDK before using SDK methods	You attempted to use the SDK features without having previously instantiated it.
