Parse additional info to get key value pair from alert record and store it in a variable

[Ash34]

Hello Folks,
I'm new to service now. I'm trying to create a flow where the trigger is from an alert. 

In the additional information of the alert, there is a key/value pair that I want to store as a variable and then use in an Action.

Additional info JSON: 

{

name: "ashutosh",

id: "1234"

}

I want to extract the id and store it in a variable. Then, use that variable in an API call (action). If someone can provide me detailed steps as I'm very new to this platform would be nice.

Hi,

Glad to know that you followed the approach I shared.

So you can use output of the sub-flow in the REST Step

please share screenshots of the sub-flow and the REST step used in main flow

I was able to create input in the rest API action and use that from the flow.

Here is how I achieved it:

1. In the sub-flow added an input variable and label as id of type string.
2. In the action of rest API, I also created input variable and named it the same as the above.
3. From the flow designer, there was an option to add a script, the key was very hard for me to find. I have highlighted the green box.
   
4. After press that button, we need to add the below javascript code provided by @Ankur Bawiskar. But we had to get to our records which were hard to find in the first line. Note: if you are trying to parse some other variable than additional_info, change it accordingly. Try to use auto-completion.
   

   var str = fd_data.trigger.current.additional_info;
   var obj = JSON.parse(str);
   var id = obj.id;
   return id;​

5. Finally test the flow. It works like a charm.

@Ash 

Did you mistakenly marked your own response as correct?

Would you mind the response which helped/guided you in right direction as correct so that member gets credit and recognition.

@Ankur Bawiskar Your response was helpful but was missing a key element which was 

var str = fd_data.trigger.current.additional_info;

A newbie like me would have completely missed it or could have never got it done. I saw this on another forum which helped me get the variable.

What we can do is, you can copy my detailed answer, I will mark that as complete this way you get your credit for helping me and other users get the exact answer. 🙂

Let me know what you think about this.
