[willemstuursma]

There is no way to set HTTP proxies now.

Hi Willem 👋

There are some problems I'd like to resolve before I contribute (I'd like to contribute to this issue since this affects me too); Are you expecting to use the native cURL proxy method? If so, there are various options regarding authentication. See the documentation that has some (version problems) and are you trying to support all various ways of authentication?

Let me know how you'd see this solution.

Thanks,
Ricardo.

I guess we should have a connection string similar to Guzzle Options for setting the proxy. The Mollie_Api_Client will then set the right properties on the cURL resource.

Let me know what your opinion is @mollierobbert. Thanks! 👍

@mollierobbert is pretty busy today. If it works for Guzzle, it'll work for us too, so go ahead.

@Ricknox any luck with this?

@holtkamp That's a pretty unique requirement of bunq.

Regardless, I think we will release a v2 of this API client somewhere in 2018H1, which will probably use a Guzzle ClientInterface that you can optionally inject.

This will be available in 2.0, which uses Guzzle as the transport. Guzzle can be configured to use proxies and can be injected in the constructor.
