borderless™ Link™ Overview


Deprecation warning!

In order to enhance security of borderless™ Link™, identifying widget with JWT token will be deprecated. New identification will have to be retrieved through a dedicated endpoint. The obtained widgetId, serving as the unique identifier, will subsequently be utilized in constructing the widget URL.

During the transition period, both authentication methods will work but we strongly advise you to switch over to new and enhanced method.

Embed the /externalContacts endpoint directly into your application with borderless™ Link™. With borderless™ Link™, recipients follow the instructions on the Widget to add their data. borderless™ Link™ automatically configures and collects the data requirements for all borderless™ supported countries. Once a user inputs their information, borderless™ will create a unique and auto-generated @handle for API payouts (example: "@^28291AS"). To learn more about borderless™ @handles please visit @Handle Overview.
