Json response to be deserialized in Apex salesforce lightning

Question

I am getting the below Json Response by hitting a RestAPI.

**

[

        "index": 0,
        "object": {
            "attributes": {

I am trying to save the values for CoachID (3028), IgpID(1872), IgpId(1911), IgpName(Dr. heath), IgpNAME(Dr Jc crook) in String variables in APex class.

I have used a map to do so but unable to get the proper values. I wanted to get the above values in a List & return that list from function.

Can anyone help me on this? I am not supposed to do this using wrapper.

Regards, Mohit

It can't be done as straight "JSON.deserialize" call because some fields are reserved keywords in Apex. How strict the wrapper ban is? I wouldn't want to type this stuff freehand but you can go to https://json2apex.herokuapp.com/, tick checkbox about explicit parser (again, since you have reserved keywords it'd happen anyway) and well, you have a ready class & cool stab at unit test / example how to use the code. It's battle-tested, if you can't use that then your project has bigger problems ;)

If you really really have to do it alone and with maps it'll be something like https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_class_System_Json.htm, example for deserializeUntyped

Thanks, I have returned the response from API in String form & handled it in JS & it working. — Mohit Mathuriya, Jul 02 '20 at 06:07
Ha, sure, that works too. If you don't need results in Apex really it'd be waste of time to parse them, just pass them straight :) — eyescream, Jul 02 '20 at 06:27
