I need help writing JSON Path Expressions

First, re-evaluate why you are writing a JSON Path Expression. Try using a mapper, or several mappers to solve your problem. Understand how to use the Mapping Root in the Mapper. If you must, continue on.

As per the docs, is a good place to start. However, it can be a little tricky to use at times, and will occasionally stop live evaluating.

Another site to consider is This one works quite well, but can be a touch opaque at times as to why things are failing. is a good place to see examples of JSON Path in action.

My JSON fails to parse and I don’t know why! is a great graphical JSON Parser and will show you exactly where you’ve gone wrong.

I want to see what SnapLogic is sending to a REST Endpoint (or set up a Mock REST endpoint) lets you create a mock REST Endpoint and define the response. Make sure to set the response content-type header to application/json if you want to parse the results into a SnapLogic object. You can use random string here)/log to explore the requests that SnapLogic is making to your new “API”.

I want to create a Mock SOAP Endpoint

This is not for the faint of heart, in the cloud, anyway.

The best way that I know of is This is doubly true if you have a WSDL already. However, you will have to mess with your WSDL so that the bindings point to your new sandbox. Also please note that the free account on this site is time limited.

If you have to create your own WSDL, the only one I know of is But, you’ll need to edit it so that it’s recognised by the WSDL parser.

I’m having trouble with Regular Expressions (Patterns) is a good place to build patterns that are compatible with SnapLogic’s implementation of Regular Expressions.
