How do I integrate Opencart with Instapago?

I have an opencart website. But I want to use Instapago as the payment gateway instead. How do I go about doing this?

I don't see an Instapago extension listed in the extension marketplace, so you'll probably need to have someone write you a custom one.

If you need to find a developer, I recommend you post a request in the OpenCart "Commercial Support" forum, which is checked by a number of OpenCart developers. You can also try checking out the OpenCart "Partners" area.
