My coworkers are interested in moving to salesforce. The web to lead capture I'm not a big fan. I would like to be able to keep our existing php scripts and post using JSON. We currently do this is pipelinedeals.com but it requires an API key to authenticate. Base on what I know of salesforce API access is only granted at the Enterprise Edition, which I cannot justify spending $125 a month per user when we currently spend $25 for full API functionality.
We are hoping to move to the basic package and still be able to post using JSON.
