Problem with Canva API Endpoint for Folder Access and Exporting Files

Hi! I’m currently trying to integrate Canva API with Make.com to fetch files from a folder and export a specific file as PNG with a transparent background. However, I’m running into the following issue:
1. I’m using the URL:

https://api.canva.com/rest/v1/folders/root/items

or

https://api.canva.com/rest/v1/folders/{folder_id}/items

But it keeps returning the error:
[404] endpoint_not_found.

2.	I double-checked that:
•	My account has access to the folder.
•	I’m using the correct folder name and/or folder_id.

Despite this, the error persists. I cannot fetch the folder contents or proceed with exporting a file.

Does anyone have experience with this or know how to resolve this issue? Am I missing any required configuration or specific step in the request setup?

Thank you in advance for any guidance!
