In Mindstudio integrations I’ve added the Client ID and Secret Key from Canva and I’m getting a connected to Canva successfully message.
When I try to run my agent it’s not connecting to Canva to run the OAuth flow test.
When I visit this URL it’s giving error tokens not valid [https://app.mindstudio.ai/integrations/oauth/redeem/canva](https://app.mindstudio.ai/integrations/oauth/redeem/canva)
**Connection to Canva failed. Missing required tokens.**

This is a follow-up to my original ticket regarding the Canva integration failure. I have performed extensive troubleshooting and believe the issue is internal to the platform’s handling of the PKCE flow.
The problem is isolated to the final **Token Exchange** step.
* * *
### **Troubleshooting Summary**
- **Credentials Check:** Client ID and Client Secret have been triple-checked and verified. Upon configuration save, the status briefly shows **“Connected to Canva successfully”**.
- **Redirect URI Check:** The Redirect URI is correctly registered in the Canva Developer Portal. The authorization step completes, and I am successfully redirected back to Mindstudio.
- **Persistent Error:** Despite the correct setup, the integration status remains **“Connection to Canva failed. Missing required tokens.”**
- **Test Flow Result:** After authorizing on Canva, I am redirected to the Mindstudio redeem URL with the error message: **“tokens not valid”**.
### **Technical Diagnosis**
This pattern of failure indicates that the flow works up to the point of redirection, but fails during the secure, server-to-server exchange of the authorization code for the final access token.
Given that this flow requires PKCE (Proof Key for Code Exchange):
- **Hypothesis:** The platform is failing to correctly utilize the temporary secret (`code_verifier`) that corresponds to the initial `code_challenge` sent to Canva.
- **Likely Cause:** The `code_verifier` is either not being generated, stored, or correctly included in the final API call to Canva’s token endpoint (`POST /api/oauth/token`).

Hi @ramelton,
Thanks for the post!
Please make sure the read and write scopes are enabled in Canva so your MindStudio Agent can use the connector:

Hi Alex, I was able now to submit my App to Canva for review that was the problem. Canva scopes were not configured correctly, thank you.

Hi @ramelton,
Glad to hear it’s fixed!
