This tutorial is a React/Next.js tutorial. It is also based on the Halliday Docs.

Instructions
Get an API Key
In order to use Halliday, you will need to get an API key. Right now the process is to email partnerships@halliday.xyz. But this may change, so I recommend checking the Halliday Docs for the most up to date information.
Integrate Halliday
Lastly, integrate Halliday Payments into your existing application with a few lines of code.
In this example, we make it so that the Halliday popup is embedded in a div with the id
halliday-embed. Such that when the user loads the page, it is already there. However you can change this so that it pops up when the user clicks a button. Check out the Halliday Docs for more information.
