Do you know the JSON Patch format? The RFC6902 defines the structure to express a list of operations to apply over a JSON Document. This format is designed to be the payload of an HTTP PATCH method.
The format isn't difficult, you can easily understand the rules and build it manually. But, I confess that sometimes I struggle with it, specially when I'm testing a PATCH to a complex object. So... I built a Tool to help me.
JSON Patch Builder Online is a simple and Open Source tool that you can use to calculate the JSON Patch needed to transform a resource/entity in the resource that you want.
I hope that this helps you.comments powered by Disqus
