How to grab the session ID from a API call

catalinp over 7 years ago

I'm looking to grab the session ID from HTTP response:

As you can see in the integration window I can see that value, but when I'm trying to query or put it into a process that value is not visible:

I know that HTTP response is a dictionary and one key is unique and has one value, but its there a way to do that in Appian without using plugins or 3rd party tools?

Thank you in advance!

Hi catalinp,

You can split the header based on comma(,) then you will have then index value of your required key so ready the value of corresponding key.

If you want I will share the code as well.

Abhay Giri that problem is that when you are running the process not all information in header is present, because somehow the Appian makes a dictionary and you can't have 2 pairs with the same key. But when is put on Integration interface is working like a charm :)

Hi,

i think you can save the header part of the service in a string then you can apply the logic which i suggested to you, as your screen shot clearly shows that you are able to get the header in your process model, so i don't think there will be any problem for that.

Regards
Abhay

I save it on OutPut as string, as you can see in the 3rd image.

now just pass this string into an expression rule and first split based on comma(,) then you will get the required index number from here then use Index function to retrieve the required value.
