Seeing payload data in Flow Designer

Question

I have a flow trigger that accepts a payload; is it possible to see what's being received by xMatters?

Environment

All versions of xMatters

Answer

Yes. You can review the payload data received by xMatters and how it is used in your flow in the Activity section of Flow Designer, or on the Signals report.

To view payload data in Flow Designer:

• Open the flow containing the trigger, and then click the Activity button to open the Activity panel.

• Select the specific execution in the Activity Stream to see what the trigger received and how data moved through each step.

On the Steps tab for that execution:

• The Body section displays the POST request issued, payload data, and response.

• The Inputs and Outputs sections for each step show which properties were available and what values were passed to downstream steps, so you can confirm that custom JSON fields are being mapped correctly.

If values are missing at a downstream step, check that:

• The custom trigger has corresponding Outputs defined for those fields.

• Those outputs are mapped into the downstream step inputs on the canvas.

• The flow routing (for example, trigger → switch → target step) is correct.

• Your trigger script correctly parses the payload (for example, using JSON.parse(input.body)) and assigns values to the trigger outputs before the flow continues.

Update the Script tab or trigger outputs as needed and resend your JSON payload to the trigger URL; then review the Activity Stream again until it shows the expected values.

The Log tab displays the processed script and any errors that occur, which can help you troubleshoot parsing, validation, or mapping issues:
