uploading a third party module to the hosting web page;

validating a proxy application programming interface (API) call received from the third party module, wherein the proxy API call includes at least a payload parameter provided by the third party module;

generating an engine API call including at least the payload parameter;

validating the engine API call; and

executing by the sand-box engine over the hosting web page the payload parameter if the engine API call is validated.

2. The method of claim 1 , wherein the validation of the proxy API call is performed by the sand-box proxy.

3. The method of claim 2 , wherein validating the proxy API call further comprising:

checking the contents of the payload parameter against at least one validation rule being selected from a set of predefined rules.
