Any update with this? I am from Spain, and "La Caixa" or "CaixaBank" is your client offering your SDK as default in PHP. I need know if this repository is maintained or if I have to fill a complaint to them about if they need to update or change the SDK to another provider. My final client is paying a montly license to use "Addon Payments" and I think that this should be maintained at least.

Please @RealexITSO I need support here and in project https://github.com/realexpayments/rxp-remote-php

5 months and nobody replies and the code is updated today with minor details. Not sure if the fee in each payment or the montly payment is justified... maybe I have to look for another provider.

Hi @shakaran, we prioritize accepting Pull Requests based on functionality requirements etc.

The SDKs updated today were related to the Hosted Payment Page to ensure compatibility with older version of the JS, Android and iOS Libraries. Is there a specific issue you are encountering?

Yes, the blocking issue to me, it is like the issue #15. My final client is using Symfony 3.3 and actually the current version of this repo don't allow per dependencies since is based in Symfony 2.7. Also I have another future client that will want integration with Symfony 4.0 and 4.1 version. So please, prioritize the support for the Symfony and Laravel versions or create diferent support branch at least.

Anyways, this is basically a PR automerge. Clicking "merge" you have it all quickly done ;)
