I am trying to access API of Apple Music API

> https://developer.apple.com/documentation/applemusicapi


After creating the JWT developer token, when i try to access the API, An error of 401 - Unauthorized occurs.


I am doing it in the following way :


1) Registering a new music identifier > https://help.apple.com/developer-account/#/devce5522674?sub=dev0416b9004


2) Creating a MusicKit identifier and private key > https://help.apple.com/developer-account/#/devce5522674 also downloading the private key file.


3) Getting the Kid (Key Id) and issuer (Team Id) .


4) Running the following code to generate the token : 


const jwt     = require("jsonwebtoken");          
const privateKey = fs.readFileSync("AuthKey_KEY_ID.p8").toString();      

const teamId     = TEAM_ID_HERE;      
const keyId      = KEY_ID_HERE;    

 const jwtToken = jwt.sign({}, privateKey, {                       
                                             algorithm: "ES256",                    
                                             expiresIn: "120d",                    
                                             issuer: teamId,
                                             header: {                             
                                                       alg: "ES256",
                                                      kid: keyId                       
                                             }             
                              });     
console.log(jwtToken);



And after that checking the code using the curl command : 


curl -v -H 'Authorization: Bearer [developer token]' "https://api.music.apple.com/v1/catalog/us/songs/203709340"


I am not sure what i am missing here. is it something related to access or is it my code.


P.S : I am the Account Holder, so it is not an issue related to role.



Thanks

Exact same issue here.

I tried different way to generate the developer token (like https://github.com/mkoehnke/musickit-token-encoder or programmatically with https://github.com/IBM-Swift/Swift-JWT) but still the same 401 results for all search API calls (even with the official Adding Content to Apple Music sample code from Apple).

Note that generating a UserToken is also failing with my developerToken.

I've done the exact same thing and couldn't get it to work. I noticed it adds in a `typ: "JWT"` to the header, so maybe it's not supposed to have that.

I am having the same problem. Tired creating the token using 4 different approaches.


When I check the token using


https://jwt.io/


I noticed that I get an error that the signature is invalid. It's the same result despite which method I use to create the token.


I know this isn't a solution, but hoped that someone might be able to help point me in the right direction.

I have exactly the same problem:

< HTTP/2 401

Been trying for three days now.

I know I did everything correct, still fails.

My "Apple Music" subscription is the free 3 month trial but I guess that should not matter?

It seems we are many developers facing the same problem, it must be some problem at Apple's end?


You can check your signed token here:

https://shawntabrizi.com/JWT-Decoder/

When I check my token(s), I get exactly the correct data back, team ID, key ID etc.

I had the exact same issue, however, it's working for me today. I don't know if that was an issue with Apple or what. I'm using the same code as the original poster.

Having the same issue. Tried creating a new Key ID and regenerating the jwtToken but still not working. Every request returns a 401 Unauthorized

OK, this embarrasing, but I had an extra character at the end of my Team ID. After correcting it, I am now able to successfully call the API. My apologies!

Per the documentation on the library, please put the payload as the first argument in the sign method


https://github.com/auth0/node-jsonwebtoken


Payload should include

{
  "iss": "DEF123GHIJ",
  "iat": 1437179036,
  "exp": 1493298100
}

per https://developer.apple.com/documentation/applemusicapi/getting_keys_and_creating_tokens
