In order to use the Payments Library, you need to create a merchant account for each payment method you would like to use in the library. These merchant account credentials should then be stored in our system and referenced when initializing the Payments Library. See the list of "next steps" below for guides on how to set up the necessary merchant accounts with each wallet provider.
Please follow this guide to store these credentials in our system for use with the Payments Library.
Managing Payments Library Accounts
Once you have created the merchant accounts necessary for the Payments Library and stored them in our system, you can manage these accounts from our portal
