Get transaction id in script from postman.

[Ruchi9]

Hi,
I am trying to get transaction id in my script from postman when api is triggered.

Tried this but it's giving undefined.
var reqheader = request.headers;
var transaction_id= reqheader.transaction_id;
gs.log('Test transaction id '+transaction_id);

I found this code somewhere so not sure if this is the correct backend name of transaction id. In that case how can I get the backend name of this field 'X-Transaction-ID' ?

Hi,

You can use this method:

getAllHeaders()

And loop through them to get the information such as:

var headers = request.getAllHeaders();
for(var i in headers){ //if the getAllHeaders was associated to the "headers" JavaScript variable
if (headers[i].name == "X-Transaction-ID") {
  gs.info(headers[i].name + ': ' + headers[i].value);
 }
}

For example

Hi Allen,

Thanks for the reply.

I tried the above logic in my scripted rest api but it's not working.
I gave log inside for statement but it seems it's not running at all as i got no logs.

Also tried request.getHeader('X-Transaction-ID'); but this is giving null

but request.getHeader('Content-Type'); is giving the expected value.

Is it because transaction id is generated everytime api is triggered ?

Hi,

Yes, the transaction ID is generated every time the API is triggered, but as far as it not working, unfortunately, you didn't supply that section of code so I could take a look. To give documentation/support towards what I supposed, here's this link: https://developer.servicenow.com/dev.do#!/reference/api/paris/server/sn_ws-namespace/c_RESTResponseV...

From here, I modified that code to focus on the one header you were wanting to use and with that, I personally tested it and it does work.

So I think there may be a small adjustment you need to make to get it to work, but you can use the link above to test sending it even in background script.
