Tasker POST call to Notion API returns 401 despite valid credentials. Example:
executeTask("userInput", { apiSecret: "secret_XYZ", dbKey: "db_new123" });
I once ran into a similar problem when working with Notion API through HTTPS in Tasker. I noticed that a 401 error was not necessarily due to wrong credentials, but sometimes due to subtle misconfigurations with the API’s expected formatting. In my case, making sure that the secret and database key were exactly as required, without additional spaces or encoding issues, made the difference. Also verifying that the HTTP headers were correctly formed helped clear up my issue. Double-checking the documentation for any recent changes to authentication was also a key step in solving it.
