Payment gateway

[Branko Vukelic]

Can anyone recommend a payment gateway that offers Python SDK that
would work on GAE? I've looked at a few but so far Python SDK is
either not offered at all, or offered with C-based code/dependencies.
If there's no such a solution, what payment gateway would you
recommend that possibly has nice JSON or REST API?

I would for lots of reasons. Use a "meta" gate way. Using a "proxy" built in another language handle your payments and send the response to GAE. The 10 second limit on GAE Fetch will often make payment gateways time out.
You are better to Use an ajax element on the page, do the submit to your other platform, and when the payment is approved have it update a data field so that the Ajax which has been polling every 500ms can say "confirmed" or "declined"

Thanks for the tip, Brandon. I'll look into this option, then.

We've been playing with Brain Tree which does have a pretty nice API:

And +1 to Brandon's "meta" gateway suggestion. Store things like
invoice-ids in your own database on a per-account basis instead of
having to hit the payment gateway all the time. Scales much better.

I am using Spreedly to handle payments. I use it for subscriptions, but I'm pretty sure it can handle more than that. It has a wonderful REST api and even provides a nice POST callback with customer ids when a sale is made so you dont have to poll the server for the invoice.

I've never used POST callbacks. How do those work?

When a customer pays for something through spreedly, the service POSTs to a url that you specify with the changed customer's ids in the body of the request. Then you can fetch the new data using those ids, instead of having to poll a service.
