Try Catch

The Try Catch activity provides structured exception handling within workflows. Use it to define fallback actions for API failures, invalid data, or unexpected errors.

Using Try Catch activity

To add a Try Catch activity to your workflow:

On your API workflow designer canvas, select the plus (+) icon. The Add activity menu appears.
Select Try Catch.
In the Properties panel, provide a name for your error.
Add activities to the Try block. These are the activities monitored for errors.
Define the error-handling logic in the Catch block. If any step in the Try block fails, execution transitions to the Catch flow.
Test the workflow to execute the activity and generate output fields for later use.

Accessing error details

When an error occurs in the Try block, the Try-Catch activity exposes structured error details. To access the error details, use $context.outputs.Try_Catch_X.error.

The error object maintains a consistent structure, as follows:

"Try_Catch_1": {
        "error": {
          "type": "<runtime error source>",
          "title": "<summary error message>",
          "status": <response status code>,
          "detail": "<detailed error message",
          "data": {},
        }
      }"Try_Catch_1": {
        "error": {
          "type": "<runtime error source>",
          "title": "<summary error message>",
          "status": <response status code>,
          "detail": "<detailed error message",
          "data": {},
        }
      }

The error details are:

type—Indicates the runtime source of the error.
title—Provides a concise error summary.
status—The HTTP status code (if applicable).
detail—Offers a detailed explanation of the error.
data— Includes additional metadata about the failed task. This field may not always be populated.

You can reference these properties to build structured error responses or trigger alerts.
