Initializing the SDK

It is necessary to initialize the SDK at the launch of your application in the didFinishLaunchingWithOptions method of your AppDelegate. This allows you to configure the SDK with your data.

1. Import the LyraPaymentSDK into your application
2. Call the initialize method with the following parameters:

   Parameter	Format	Description
   publicKey	string	Fill in your public key (available in the Settings menu > Shop > REST API keys your Expert Back Office)
   options	[String: Any]	Dictionary that allows you to configure the behavior of the SDK.

   The possible keys in this dictionary are:

   Keys	Format	Description	Required
   apiServerName	string	Expected value: REST API server name (available in the Settings menu > Shop > REST API keys of your Expert Back Office)	Required
   cardScanningEnabled	Bool	Enables/Disables the card scan feature (see the iOS integration guide)	Optional
   applePayMerchantId	string	Expected value: APPLE_MERCHANT_ID See Configuring the contracts chapter to learn more about your APPLE_MERCHANT_ID which is actually your Apple Pay contract number.	Required

   Example of a call

   <div class="doc-component-wrapper"> <doc-code-block> <div class="doc-code" data-languages="swift, objective_c"> <pre data-language="swift"> //Active Apple Pay functionality configurationOptions[Lyra.applePayMerchantId] = APPLE_MERCHANT_ID </pre> <pre data-language="objective_c"> //Active Apple Pay functionality [configurationOptions setValue:APPLE_MERCHANT_ID forKey:Lyra.applePayMerchantId]; </pre> </div> </doc-code-block> </div>
