Adding a button in restaurant POS menu that takes user to my application temporarily

Hi there,

I’d like to add a button to my customers restaurant POS menu.

Upon checking out a customer, I want them to click the custom button and have it take them to my website, with the sale details in the URL parameters. Once they’ve finished on my website, the browser with my app open will close and they will be taken back to finish the checkout on Square’s POS.

It’s important that I associated the transaction at checkout with the interaction on my website. This was easy to do with Lightspeeds Retail API, but I’m struggling to figure out how to do this with Square.

Can anyone lend me a helping hand please? Is there a better way to associated the transaction at checkout with an interaction on my website?


:wave: Unfortunately the ability to app switch with the Restaurants POS isn’t available. :slightly_smiling_face:

Thanks for the heads up @Bryan-Square

Is there any other way I can associate a sale on the Square POS with an external interaction on my website? For example, I want to associate the customer with a certain transaction.

Yeah, your external integration can consume webhooks that have information about the sale. :slightly_smiling_face:

Great. Thanks for your help!
