BRAccountLinkingManager

Objective-C

@interface BRAccountLinkingManager : NSObject

Swift

class BRAccountLinkingManager : NSObject

Use this interface to manage users’ linked retailer accounts for parsing e-receipts. Here is the basic flow:

Implement UI to capture the user’s credentials to one or more retailers from the supported list (see BRAccountLinkingRetailer enum)
Store these using -[BRAccountLinkingManager linkAccountWithCredentials:]
Call -[BRAccountLinkingManager grabNewOrdersWithCompletion:]
The callback to this method will return all order details available since the most recent successful invocation
