Seeking Assistance: Receiving 401 Error when Creating a Playlist on Spotify

[mondayy]

Hello,

 I am reaching out to seek assistance regarding an issue I've been facing while attempting to create a playlist on Spotify. Unfortunately, I keep encountering a persistent 401 error, which indicates an authentication or authorization problem.

Here's a brief description of the issue:

• Problem: When I try to create a playlist using the Spotify API, I consistently receive a 401 error.
• Context: I have checked my credentials and verified that they are accurate. Additionally, I have ensured that the required scopes for playlist creation (playlist-modify-private or playlist-modify-public) are included. However, the error persists.
• Troubleshooting: I have followed the suggested troubleshooting steps, including refreshing the authentication token, reviewing my API keys, verifying permissions, and clearing cache and cookies. Unfortunately, none of these actions have resolved the issue.

I am using Reactjs and axios for my project and would appreciate any guidance or insights from anyone who has experienced a similar problem or has expertise with the Spotify API. If you have any suggestions, workarounds, or advice on how to overcome this 401 error and successfully create playlists on Spotify, your assistance would be highly appreciated.

Thank you in advance for your time!

P.S I have attached my code as well. 

Best regards, Mondayy

I don't see a client secret in your code, so did you implantaten the Authorization Code with PKCE Flow?

[mondayy]

No I used the Authorization code flow without the PKCE Flow. Do I need to do PKCE Flow?

That's a mistake from my side. I didn't know you didn't have to use the client secret in one case of the Authorization Code flow.

Because I couldn't fix it myself, I asked ChatGPT.
