HI All

I have been struggling with this json structure for some time now. Im looking for assistance in flattening this json message. I assume that ruby iteration would be needed here but all the examples I try dont seem to work for me. The data comes from IBM API COnnect event export as a json document.

Here is some data. It should be noted that number of items in the embedded jsons are dynamic. Id like to flatten the response\_http\_headers in this example.

{  
"api\_name": "app",  
"status\_code": "200 OK",  
"request\_method": "GET",  
"developer\_org\_name": "dev",  
"http\_user\_agent": "Healthcheck",  
"resource\_path": "get",  
"@version": "1",  
"response\_http\_headers": [  
{  
"Content-Type": "application/json"  
},  
{  
"Date": "Mon, 19 Nov 2018 15:49:21 GMT"  
},  
{  
"X-Global-Transaction-ID": "4538538753"  
},  
{  
"User-Agent": "IBM-APIConnect/5.0"  
},  
{  
"accept": "application/json"  
},  
{  
"Via": "1.1 AQAAACbdihddsQb8-"  
},  
{  
"X-Client-IP": "107.1.22.4"  
},  
{  
"Access-Control-Expose-Headers": "APIm-Debug-Trans-Id, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, X-Global-Transaction-ID"  
},  
{  
"Access-Control-Allow-Origin": "\*"  
},  
{  
"Access-Control-Allow-Methods": "GET"  
},  
{  
"Access-Control-Allow-Credentials": "false"  
}  
],  
"org\_name": "org"  
}

Thanks
