Workflow Calls
Inspect the inputs, execution trace, and outputs of a workflow call in the editor
Calls open in the workflow editor, on the same graph you use to build the workflow. This lets you inspect a result and change the configuration behind it without leaving the page.
Open a call
Select Calls under the workflow in the sidebar. The editor opens the list of calls and selects the newest one. Use the list to switch to another call.
You can also open a call from these places:
While a call is selected, the Tests tab is labeled Call. To leave the call, select ‹ Tests in the panel header, or × on the call label at the top right of the graph.

Find a slow or failed step
The graph shows which steps ran. Each step that ran shows its status, its execution time, and the function version it used. The workflow node shows the same for the whole call.
Select a step to go to it in the Call panel, then expand it to inspect its attempts, errors, and outputs. For a call that is still running, the status and duration update as processing continues.
Compare the input with the result
Select Input preview in the graph menu to show the call's source files in place of the graph. Select Graph to return. The call details stay in the right panel, so you can compare the input with the result.

Edit while a call is selected
Switch to Edit or Forge to change the workflow and keep the call selected. In Edit, select a step to see the call's output for that step in the drawer below the graph. You can resize or collapse the drawer. If the step ran more than once, use the arrows to move between runs.
Calls from an earlier version
A call always shows what ran at the time. If the workflow has changed since then, the call label at the top right of the graph shows the version that the call used.
- Same steps and connections: The graph stays editable. Selecting a step that ran on an earlier function version opens that version in Version History. Select Edit latest to edit the current version of the step.
- Different steps or connections: The graph is read-only and shows the workflow as it was. Switching to Edit or Forge asks you to confirm, then leaves the call.
Rerun and correct outputs
If a call has failed or otherwise needs to be retried, Rerun starts a new call with the same inputs.
To confirm a result or fix incorrect values, open Corrections in the workflow sidebar. The call you selected stays open.
