get invoice from transaction (id)

[Sellighsphire]

Hello,

I've already done some integration. Payments are fine.

My new customer wants to show invoices from his customer on his own site.

Therefore I'm looking for some billing-info, paypal already provides.

But I can't find any.

How do I get an (designed) invoice from paypal using the transaction-id from prior payments?

Kind regards

Jens
