We have Salesforce in house and need a proxy server to send API calls to an external Web Service interface (Box). Since Salesforce only allows 10 callouts per apex invocation, we need an external cloud server to send these callouts. Not having the money for CastIron or even Pervasive, I was wondering if we could implement this on Heroku?
Of course, Heroku needs to be able to receive Soap messages and send them.
If it can, this would be all we need for our Box integration. (I think)
Does Heroku have addons that receive Soap Messages?
Yes, Heroku is designed for, among others, use cases like this.
