Embedded payload in a JSON - How to define and process

We're on 7.3 and I have a working program processing JSON transactions. I'm to start processing some new transactions and am not sure what issues I might have. The program currently uses Data-Into and YAJLINTO.

The new transactions looks like this:


{"id":396,"payload":"{\"name\":{\"firstName\":\"JAMES\",\"lastName\":\"SHUE\",\"id\":null,\"suffix\":null,\"middleName\":\"B\"},\"dob\":\"1955-01-01\",\"someNumber\":\"123456789\",\"tin\":null,\"workPhone\":null,\"homePhone\":null}","internalAccountNumber":12345,"as400AccountNum":12345678902,"eventType":"DELETE","source":"SUCCESSOR","status":"PENDING","submitDate":"2021-04-08 15:37:03","createdDate":"2021-04-08 15:37:03","createdBy":"unknown","lastModifiedDate":"2021-04-08 15:37:03","lastModifiedBy":"unknown"}

My question is about the "payload" object which is a JSON inside of a JSON.


1. Should this be defined as just a nested array? Something like this:

dcl-ds txSuccessorJSONDoc qualified;
ID VarChar(20) inz('0');

Dcl-ds PAYLOAD;
FIRSTNAME varchar(14) inz('');
MIDDLENAME varchar(13) inz('');
LASTNAME varchar(20) inz('');
SUFFIX varchar(3) inz('');
DOB varchar(10) inz('');
SOMENUMBER varchar(9) inz('');
TIN varchar(9) inz('');
WORKPHONE varchar(10) inz('0');
HOMEPHONE varchar(10) inz('0');
End-Ds;

USERID VarChar(128) inz('0');
INTERNALACCOUNTNUMBER VarChar(9) inz('0');
AS400ACCOUNTNUM VarChar(12) inz('0');
EVENTTYPE varchar(10) inz('');
SOURCE varchar(50) inz('');
STATUS varchar(50) inz('');
SUBMITDATE varchar(25) inz('');
CREATEDDATE varchar(25) inz('');
CREATEDBY varchar(128) inz('');
LASTMODIFIEDDATE varchar(25) inz('');
LASTMODIFIEDBY varchar(128) inz('');
CREATEDDATE varchar(25) inz('');
End-ds;


1. I'm told the embedded slashes in the payload object should be recognized and ignored by the JSON processor. Do I have to do anything different for that portion of the JSON to process? I'm not finding much on this with Google.

TIA
