Capture and Debug Salesforce Network Traffic with Fiddler for Support Troubleshooting

Data pubblicazione: Jun 28, 2026
Descrizione

To install Fiddler, you need Administrative rights on your local machine. If you are unsure or experience problems installing the application, consult your IT department. The steps below may vary slightly depending on the version of Fiddler you are using. For questions specific to the Fiddler software itself, contact Telerik Fiddler Support.
Fiddler is a tool for analyzing HTTP and HTTPS transactions. It is a simple-to-use version which can save logs as .saz files that you can send back to the Salesforce support team.

Risoluzione

If your Salesforce support agent has requested a network traffic capture, follow these steps to download, configure, and run Fiddler (by Telerik), then share the .saz log file with your support case.

Steps to Capture Network Traffic Using Fiddler

  1.  Download Fiddler from Telerik to the local machine.
  2. Complete the installation and run the application.
  3. In Fiddler, from the top menu click on Tools > Options > HTTPS > Capture HTTPS CONNECTs.
  4. Check the box for Decrypt HTTPS traffic and agree to any prompts to install the needed certificate for HTTPS decryption.
  5. Select Ignore Server Certificate errors and click OK to exit the Fiddler options.
  6. Ensure Capture traffic is selected under the File menu, or press F12.
  7. On Windows machines, the WinConfig AppContainer Loopback Exemption Utility needs to be configured for at least Desktop App Web View and Office apps.

Configuring WinConfig (Windows Only)

If the prompt is not accepted at startup in Fiddler, select the WinConfig button to load the "WinConfig AppContainer Loopback Exemption Utility." Select Exempt All and click Save Changes.

Capturing and Saving the Session

  1. Run the application or processes that need debugging and perform regular work until the issue seems to have re-occurred.
  2. In Fiddler, navigate to File > Save > All Sessions and save the file as a .saz file.
  3. Close Fiddler.
  4. Compress the .saz file by right-clicking it and selecting Send to > Compressed (Zipped) folder.
  5. Attach the zipped file to your Salesforce support case along with the exact time the issue occurred. You may also email it directly to your support representative.
