Debug Salesforce Flows with Asynchronous Apex is an essential skill for Salesforce admins and developers. While debugging standard Flows is usually straightforward—until asynchronous Apex enters the picture. When you debug Salesforce Flows with Asynchronous Apex (such as Queueable, @future, or Batch classes), execution shifts to the Apex job queue. This blog will guide you through how to debug Salesforce Flows with Asynchronous Apex using real-world scenarios, step-by-step instructions, and effective tools.
In this blog, we’ll explore:
- A real-world example where a Flow triggers a Queueable Apex class.
- Step-by-step guidance on how to effectively debug asynchronous behavior.
Architecture Overview
This section covers the system architecture used to debug Salesforce Flows with Asynchronous Apex components:
- A Record-Triggered Flow runs on the Account object.
- The Flow passes the Account Id to an Invocable Apex method.
- The method collects the IDs and triggers a Queueable Apex class.
- The Queueable class performs logic (e.g., data retrieval or processing) and logs the outcome.
This design is useful when:
- You want to shift heavy logic from Flow to Apex for performance reasons.
- You’re handling long-running operations (e.g., bulk processing, API calls).
- You need to trigger everything from a declarative Flow.
Code Overview
- Queueable Apex Class: Handles the main logic asynchronously.
- Invocable Apex Class: Exposes the Queueable trigger method to Flows.
- Record-Triggered Flow: Starts the process based on changes to an Account.
Step by Step Debugging Guide
To debug Salesforce Flows with Asynchronous Apex, follow these 5 practical steps:
- Enable Debug Logs for the User
- Go to Setup → Debug Logs
- Add the user triggering the Flow
- Set the following log levels:
- Apex Code: FINE
- System: DEBUG
- Trigger the Flow
- Create or update an Account record
- This starts the Flow, which invokes the Apex method
- The method enqueues a Queueable job
- Review the Initial Flow Log
- Go back to Debug Logs
- Open the first log related to the Flow execution
- Confirm the Flow successfully called the Invocable Apex method
- Monitor the Queueable Job
- Navigate to Setup → Apex Jobs
- Look for the job with type Queueable
- Check its status (e.g., Completed or Failed).
- Inspect the Queueable Execution Log
- Return to Debug Logs
- Open the second log corresponding to the Queueable job
- Review
System.debug()outputs to verify execution details
Conclusion
Debugging asynchronous Apex triggered from Flows can feel like chasing ghosts but it doesn’t have to be. With proper debug log setup, Apex job tracking, and structured logs, you can confidently monitor and verify every step of the execution.
