Extracting payload Data from a trigger

We have a trigger from Service Titan that is returning a large payload of data.  There are a number of custom fields that come in the payload and we need to extract one of the custom fields.  I haven’t been able to find much documentation on how to extract trigger data that is coming from another application as the start of the trigger.  We have to connect to the Service Titan tigger as Zapier is listening for the data from that connection in order to start the process.  (we have many customers we provide this service for and we have to conenct via the Service Titan App.  I would like some assistance on how I might be able to extract data from the returned payload sent from the starting Trigger. 


I’m trying get the value of Job Summary to Post in this example payload.  The Name and typeId values are always the same every completed job.

Hi @rfincke 

If you’re using the Webhook app as the Zap trigger, then you can try to Pick Off a Child Key as shown in the screenshot to help isolate the desired value.

Otherwise you’ll likely have to use a Code step to handle the isolation of the desired data points and value.

The Formatter > Utilities may have some options worth exploring.



Also make sure to reference the available help articles for each app…

Hey @rfincke, hope you’re well, I just wanted to check in here!

Were you able to get things working based on the information Troy shared, or can we still help?

For this particular workflow, if we don’t want to pick off a child key here, you would need to use a Code step to build some scripting for parsing the data and converting it into the format you need. Then you can take the result of that code step and use it in any remaining steps of the zap.

The scripting itself for the Code step would be unique to your use case and how you want the data to be reformatted.

If we’re only interested in getting the data from Job Summary, I believe the Pick Off Child Key setting for the Webhook trigger that Troy mentioned would be the most straightforward solution here.
