Ive created a fiddlescript rule with the help of many people on this fourm, thank you.

The script would check for a specific json object from the get request in the decoded response body from an application and once the request response body has found object:value, automatically send the a portion of the json value back to a different URI as a post request with the same header information such as cookies along with connection keep alive.

When the script is activated upon arrival of said content I receive an error. I assume its something to do with the json object value.

static function OnBeforeResponse(oSession: Session) {

if (oSession.oResponse.headers.ExistsAndContains("Content-Type", "application/json")) {

oSession["ui-backcolor"] = "blue";

oSession.utilDecodeResponse();

}

if (oSession.oResponse.headers.ExistsAndContains("Content-Type", "application/json") && oSession.utilFindInResponse("faceId", false) > -1) {

oSession["ui-backcolor"] = "green";

oSession.utilDecodeResponse();

var oBody = System.Text.Encoding.UTF8.GetString(oSession.requestBodyBytes);

var j = Fiddler.WebFormats.JSON.JsonDecode(oBody);

var facId = j.JSONObject["faceId"];

var reqBod = '{"faceId":"' + facId + '"}';

oSession.oRequest.headers.HTTPMethod == "POST";

oSession.utilSetRequestBody(reqBod);

oSession.url = "https://urltosendpostrequest.com/Search";

FiddlerObject.utilIssueRequest(oSession);

}

Ive been referencing many different pages and fiddlerscripts on this topic and have gotten this far only from a little knowledge of coding and much googling. One code stood out. I dont take credit for this.
