Is it possible to wrap json in json field like a string?

As Marc B noted, inner quotes must be escaped.

{"requestBody":"{\"field1\":111111,\"field2\":\"someValue\"}"}

Fiddle:

JSON-encoded stuff is just a string. If you want to embed json-in-json, then the "inner" json has to be encoded into json itself.

e.g.

$inner = {"foo":"bar"}
$outer = {"container":"{\"foo\":\"bar\"}"}

Now the inner json isn't json anymore. It's just a string that happens to kinda/sorta look like JSON.

It won't be pretty, but if you base64 encode the JSON payload, you can be sure it won't be parsed unexpectedly.

{  
    "requestBody": "eyJmaWVsZDEiOiAxMTExMTEsImZpZWxkMiI6ICJzb21lVmFsdWUifQ=="
}
