Is it possible to publish data from one salesforce to PHP apart from using outbound messages(as it cant send the attachments). I have a requirement where the website built on PHP has to be updated according to the data updated in salesforce.
I am able to integrate PHP using toolkit(SOAP API) and Restful (Oauth settings). But both of these methods need an API user. As I need to establish one way integration (similar to outbound message, but capable of sending attachments (like images and PDF's too) without having to use a salesforce licensed user.
Any pointer will be extremely helpful.
