Initialize

Initialization of the PayContactlessEmbed Library

After invoking the start method of PayContactlessEmbed, the next crucial step is to initialize the Embed library. This function serves as a foundational call; subsequent functions from the library will be inaccessible unless the Embed library is properly initialized.

To facilitate this, the function requires an InitializeListener interface as an argument. It's essential for the merchant application to implement the InitializeListener class, as the library leverages its methods as delegates, ensuring seamless communication and functionality between the app and the SDK.

PayContactlessEmbed.getInstance().initialize(@NonNull String apiKey, @NonNull MerchantInfo merchantInfo, @NonNull InitializeListener listener)

Handling Initialization Outcomes in PayContactlessEmbed Library

Upon successful completion of the initialize function, the onSuccess method is triggered. This will return a deviceId to the integrating application, signifying a successful initialization.

However, should there be any issues during initialization, the onFailure method will be activated. In the event of such a failure, it's imperative to diagnose the error and undertake the necessary corrective measures. For a comprehensive understanding of possible errors and their resolutions, please refer to the Error Handling section.
