    Integration Details

    The first step involves loading the Flex Pay Agent Library by executing the up.js code snippet included below, in your payment page.

    The up.js is a snippet of javascript code that will retrieve and load the Flex Pay library asynchronously into a window object.

    (function (u, p, l, i, f, t, o, b, j) { u['UpLiftPlatformObject'] = f; u[f] = u[f] || function () { (u[f].q = u[f].q || []).push(arguments) }, u[f].l = 1 * new Date(); b = p.createElement(l), j = p.getElementsByTagName(l)[0]; b.async = 1; b.src = i + '?upcode=' + t; j.parentNode.insertBefore(b, j); o = u.location.host.match(/[\w-]+\.\w{2,3}(:\d+)?$/); if (o) o = o[0]; u[f]('create', t, o) })(window, document, 'script', 'https://tag.uplift.com/external/up.js', 'up', 'UP-XXXXXXXX-XX');

    Every up.js snippet is unique per partner with a specific UP-code. Customize the code above by replacing UP-XXXXXXXX-XX with your assigned UP-code.

    ⚠️ Note that you will be provided a separate UP-code for Testing and for Production prior to development. Also note that using the Testing (Developer) UP-code creates debug messages for your visibility, these will not be shown when using the Production UP-code.

    Additionally note that if you also have a website integration with Flex Pay, you will have separate UP codes for each channel.
