Not authenticating with session tokens

Shopify Apps

Topic summary

A developer is stuck on the “Not authenticating with session tokens” error during Shopify app review submission. The app was built using Shopify’s official Remix.js starter template, which should include proper authentication setup by default. Despite having successfully submitted two other apps in 2024 without issues, this new submission has been blocked for 4 days with minimal support from Shopify.

Suggested troubleshooting steps:

  • Verify OAuth and session token handling in app/routes/auth.jsx
  • Confirm App Bridge is properly configured for stateless authentication
  • Test session token retrieval using browser dev tools (window.Shopify.sessionToken.get())
  • Ensure backend validates session tokens on every request
  • Update to the latest @shopify/remix-app version, as recent updates address session handling bugs
  • Try reinstalling the app and clearing cookies
  • Use Shopify’s OAuth playground to test token functionality

Community members note this is a widespread issue affecting many developers with the new session token requirements. One responder referenced a similar case with potential solutions in another community thread.

Hi guys, i’m trying to submit my app for review but i got stuck at “Not authenticating with session tokens” step.
The app was made with starter template remix.js from shopify, which has all of those things already installed. Has been 4 days no response from shopify, they said to get help from community because they can’t do anything about this which is kinda nasty to be honest is a simple app. I got 2 more apps builded in 2024 and was flawless when come to submit the app for review but this new thing has been an issue for most of us.

How do you manage this issue?

Hello there @Ionuts1 I suggest you look at this reply given when another community member had a similar issue here https://community.shopify.com/c/shopify-discussions/shopify-app-submission-missing-authentication-with-session/td-p/2910744

Hopefully you can find some useful pointers in there. Also you mentioned that the 2 others app you submitted didn’t have this issue, so are there any differences between those two and this one in particular that you can try to identify?

Shopify’s new session token requirement has been tripping up a lot of devs. Since you’re using the Remix.js starter, double-check that you’re properly handling OAuth and session tokens in app/routes/auth.jsx or wherever your auth logic is. Also, make sure your app is using App Bridge correctly, Shopify wants everything to be stateless now.

Try logging session tokens in the browser dev tools (window.Shopify.sessionToken.get()) to see if they’re actually being retrieved. If it’s still acting up, sometimes just reinstalling the app and clearing cookies fixes weird auth issues. If all else fails, hit up Shopify Dev forums or Discord—way faster than waiting on support ?‍

Maybe since you’re using the Remix starter template, double-check that your app is actually verifying session tokens on every request. Sometimes, even though the setup is there, the implementation isn’t fully connected

Try using Shopify App Bridge to make sure session tokens are being sent properly, and confirm that your backend is validating them correctly. Also, check if your app is running on the latest @Shopify_77 /remix-app version—some updates fix session handling issues. If all else fails, test it using Shopify’s OAuth playground to see if your tokens are working as expected
