Get external customer details from barcode reader to send it with event in webhook

Hello,

I am currently using a Square POS system and need some assistance with integrating it with my external application. Here’s what I am looking to achieve:

1. User Identification via Barcode: I have unique barcodes for my customers, which I would like to scan at the point of sale to identify them.
2. Sending Data to External App: When a transaction occurs, I want to send the transaction data, including the scanned barcode information, to my external application via a webhook.
3. User Matching: My external application maintains its own user list. I need to match the user identified by the barcode against this list.
4. Updating Payment Information: If a match is found, I want to update the relevant payment information in my external application.

Could anyone provide guidance or examples on how to:

1. Integrate barcode scanning with Square POS to identify users.
2. Add barcode information to the transaction data.
3. Configure Square to send this enhanced transaction data via webhooks to my external application.

Any help or pointers to relevant documentation would be greatly appreciated.

Thank you!
