Provider’s LiveApp

As explained in the Buy Integration section, you need to modify your LiveApp to recognize the parameters we are passing to you, with some particularities compared to the version found in the Discover section.

Your LiveApp must:

• Respond to specific LiveApp URLs to adapt to the flow inside Ledger Live.
• Follow specific flow/UX requirements:

LiveApp URL

The LiveApp needs to respond to a URL with certain parameters. LiveApp URLs are used to open your LiveApp with the quote values that the user has already entered in Ledger Live.

• accountAddress: Destination address to deposit the crypto.
• cryptoCurrency: The cryptocurrency that the user wants to buy. It will contain the providerId value to identify the crypto.
• fiatCurrency: The fiat currency that the user wants to spend.
• fiatAmount: The fiat amount that the user wants to spend.
• cryptoAmount: The crypto amount that the user wants to buy.
• mode: buy or sell. In this case, always buy. It’s required that you share the same base widget URL for both usages.
• paymentMethod: The preferred payment method of the user.
• bankResidency (optional): The bank residency of the user.
• buySessionid: ID used by Ledger to track transactions and their completion statuses.
• language: The language preference of the user set in Ledger Live.
• theme: The theme preference of the user set in Ledger Live.
• platform: The platform used by the user (mobile/desktop).
