How to integrate SumoLogic with OpenReplay and see backend errors alongside session recordings.

1. Create a new Access ID and Access Key

Section titled 1. Create a new Access ID and Access Key
  1. Login to your SumoLogic account.
  2. Go to the Access Keys page.
  3. Click on + Add Access Key.
  4. In the name put “openreplay” and click on Create Key.
  5. Copy the new Access ID and Access Key as we need them for our integration.
  6. Click on Done.

For more information about creating an Access ID and Access Key, please refer to this documentation.

3. Propagate openReplaySessionToken

Section titled 3. Propagate openReplaySessionToken

To link a SumoLogic event with the recorded user session, a unique token has to be propagated from your frontend to your backend on each request you want to track. This can be done using a custom HTTP header. In the below example, we use the fetch function to send that header.

const headers = {
  Accept: 'application/json',
  'Content-Type': 'application/json',
if (tracker.getSessionToken()) { // or window.OpenReplay instead of tracker if you're using the snippet
  headers['X-OpenReplay-SessionToken'] = tracker.getSessionToken(); // Inject openReplaySessionToken
fetch('', {

In order for OpenReplay to associate a SumoLogic message with the recorded user session, a unique token has to be propagated as part of each backend error you wish to track.

Below is an example in Python using Monkey Patching.

import sys
import traceback
old_tb = traceback.print_exception
old_f = sys.stdout
old_e = sys.stderr

class F:
    def write(self, x):
        if OPENREPLAY_SESSION_TOKEN is not None and x != '\n':
            old_f.write(f"[openReplaySessionToken={OPENREPLAY_SESSION_TOKEN}] {x}")

    def flush(self):

def tb_print_exception(etype, value, tb, limit=None, file=None, chain=True):
        value = type(value)(f"[openReplaySessionToken={OPENREPLAY_SESSION_TOKEN}] " + str(value))
    old_tb(etype, value, tb, limit, file, chain)

traceback.print_exception = tb_print_exception

sys.stderr = F()

The name of the tag openReplaySessionToken is case sensitive.
