Creating a JSON object
Here is how to create a JSON object using the Object-Construct card:
Note that field names were renamed, and the result is this JSON object:
Searching a JSON object
Thanks to Bryan Barrows (Workflows Product Specialist at Okta) for sharing this flow.
This example from Bryan shows how to search a JSON object.
You can download the JSON file used in this example.
The goal is to find the Battery Condition value.
This is how the flow works:
- The first card, the JSON-Parse card, creates the JSON object from a string. In your situation, you might be getting the JSON from another card such as a search or API call
- The List-Filter card finds the objects where the name is set to Battery Condition
- The List-Collapse card transforms a list of objects into a single object
- And finally, the Object-Get Multiple card retrieves the value property that holds that battery condition
Reducing a list to a single value (how to use the List-Reduce card)
This blog post has three examples of how to use the List-Reduce card.
The examples are:
- A list of numbers – sum all the numbers
- A list of numbers – find the largest (or smallest) number
- A list of messages (text) – create a single message containing all the messages from a list
