Documentation 2.1 • Napster API

Napster API Version 2.1 Overview

Developers can interact with the Napster Platform in a number of ways. These docs aim to make the process as clear and simple as possible.

About this Version

This is the documentation for Napster API version 2.1.

Changelog can be found here.

Check out the versions endpoint for a quick and easy way to stay up to date with version additions, changes, and more.

Versioning

API calls should specify the version in the path.

/v2.1/artists/art.978?limit=5&catalog=DE

API calls are defaulted to the latest stable version when no version is specified.

Clients should always specify version because, when a new version is released, they will get documents that they may not be able to interpret!

Getting Started

The first thing you'll need is an API key. All of our metadata requests (e.g., artist details, album listings, and so on — all listed at left) require an API key as a header in request:

curl -X GET  -H "apikey: {api_key}" "https://api.napster.com/v2.1/artists/top"

You can get one by creating an app.

We've provided an API key in these docs in order to make it easy for you to get started. Resist the temptation to use it in your app! It's throttled, and you'll be missing out on some additional features and analytics as well.

Note that, throughout this documentation, there are links that have API set as a parameter but, in practice, you should always set it in the apikey header of your request.
This enables you to better take advantage of caching.

Additionally, calls made on a member's behalf — e.g., adds to library, playlist manipulation, recent activity, favorites, etc. — require an OAuth access token. See below for documentation and examples.

Common Features

Cross-Origin Resource Sharing (CORS)

In general, we're CORS-friendly.

API Rate Limits

When you create an Application, your base rate limit is set at 5 requests/second. You can view your Application's rate limit by clicking into the Application details in the My Applications section of the portal.

If you have exceeded the rate limit, you will receive a 429 error similar to the following:

{"code":"TooManyRequestsError","message":"Rate of 5/sec has been exceeded for this application"}

If you'd like to increase your Application's rate limit, please make an inquiry to api-feedback@napster.com

Paging

Most of the APIs you'd expect to support paging, do (charts lists, etc.). Use limit and offset parameters to get what you want, like so:

The max limit supported is 200. If an invalid limit , a negative limit or a limit higher than 200 is passed, a 400 error will be returned.

International Catalog

Unless otherwise specified, all metadata requests will be routed to the US catalog. If you'd like to use a specific catalog other than US, just pass in the two-letter country code (which is case-sensitive)

Authenticated requests (e.g., those made with OAuth access tokens) will be routed automatically to the member's default catalog.

Napster uses ISO 3166-1 alpha-2 country codes to identify different countries' catalogs.

Language support

Unless otherwise specified, all requests will return English (US) content. If you'd like to use a specific language, other than English (US), just use lang query parameter to pass in the first two segments of language string:

Authenticated requests (e.g., those made with OAuth access tokens) will be routed by default to the member's language obtained from the member's account-configured language.

Language support is only available for APIs that have examples showing how to use it.

Napster uses IETF RFC 5646 language codes to identify different languages.

Pretty Print JSON

All the API calls are minified by default. You can pretty print the JSON object if you add pretty=true parameter to API calls.

/v2.1/artists/art.978?pretty=true&limit=5

Filter Streamable Content

Many api calls support the isStreamableOnly=true flag. This query string parameter will filter out content that is not streamable.

WARNING Passing this flag will make the totalCount value inaccurate on many endpoints. You will need to paginate until no more data is received to ensure you are at the end of the list. If you do not pass this flag, then all pagination values will be accurate.

Errors

Napster API attempts to return appropriate HTTP status codes for every request.

Status codes

Code	Text	Description
200	OK	Success!
201	Created	The request has been fulfilled and resulted in a new resource being created. The newly created resource can be referenced by the URI(s) returned in the Location HTTP header field of the response.
202	Accepted	The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place.
204	No Content	The server has fulfilled the request but does not need to return an entity-body
400	Bad Request	The request was invalid or cannot be otherwise served. A response error message may explain reasons in more detail.
401	Unauthorized	Authentication credentials were missing or incorrect. If you are accessing metadata API endpoints only with apikey, check that it is valid.
403	Forbidden	The request is understood, but it has been refused or access is not allowed. This status code is used when you try to modify or access resources you do not have permission for.
404	Not Found	The URI requested is invalid or the resource requested does not exist.
405	Method Not Allowed	The method specified in the request is not allowed for the resource identified by the request URI. See response headers for allowed methods.
409	Conflict	The request could not be completed due to a conflict with the current state of the resource you were trying to update.
413	Payload Too Large	The attached object was too large. Try again with a smaller object.
423	User Account Locked	User account is temporarily locked out of Napster API services. To unlock your account you will need to wait the required 5-minute lock out window or you can reset your password.
429	Too Many Requests	Used when a request cannot be served due to the rate limit having been exhausted (throttling).
500	Internal Server Error	Something is broken. Please email all relevant details to api-feedback@napster.com.

For a more detailed and general list of status codes with explanations see here.

Error messages

When Napster API's return an error message it is in JSON format and might look something like this:

{
  code: "ResourceNotFound",
  message: "Unable to find an artist with ID 'art.test'."
}

It is very useful to observe the code (HTTP status code name) and message fields while observing or debugging responses.

Authentication (OAuth 2.0)

Napster supports the OAuth 2 standard for making API calls on behalf of a member. In general, you will need an OAuth access token for any endpoint that begins with /me . We currently support the two most common flows:

Implicit (a.k.a., the "three-legged" OAuth flow), and
Resource Owner Password Credentials (a.k.a., the "password-grant" OAuth flow)

Recommended Authorization and Authentication Process

Authorize endpoint

To obtain a token that is used to authenticate all further API calls the client will need to go through a two step process. The first step will be to generate an authorization code which is then included in the next step which will produce the final token.

Authorization endpoint has following query string parameters:

response_type Has to be value of code or token.
code_challenge_method Has to be value of s256 or plain. Client should use s256 if they are capable of hashing the code_challenge with SHA256. (Recommended)
code_challenge Value used to verify client in the 2nd step of the authentication. Should be hashed if code_challenge_method is s256 with SHA256 or plain text if method is plain.
client_id Unique identifier (ID) of the registered application making the authorization request (Your app ID can be found in the application details found in the developer portal).
redirect_uri The callback URI registered with the application making the request (see the Developer Portal for details). Note that this must be an exact match with what is registered with the application.
Optional values that will be passed in the query of the success response call:
- state
- scope
- audience

Example curl call:

"https://api.napster.com/v2.2/oauth/authorize?client_id=your_application_id&redirect_uri=http://yourdomain.com/somepath&response_type=token&code_challange_method=s256&code_challenge=aa825702d43e823cdf0e6a0cac7b756b600555ed539f7f875f4542dbf52d7b30&state=your_state_value"

In cases where error occurs during processing of request that has all of the parameters valid, response with http status code of 302 will be returned along with query parameter error without value attached to it.

Access token endpoint

This endpoint can be used to generate new tokens using refresh tokens and to generate new tokens after a successful call to the authorization endpoint. Caller will find a code query string param value in the 302 response of the authorization call. That value must be included in the body of this API call in order to generate tokens. This endpoint requires an HTTP POST with the following JSON body:

client_id Unique identifier (ID) of the registered application making the authorization request (Your app ID can be found in the application details found in the developer portal).
grant_type Can be either authorization_code or refresh_token.
redirect_uri The callback URI registered with the application making the request (see the Developer Portal for details). Note that this must be an exact match with what is registered with the application.
Values that have to be passed if grant_type is authorization_code
- code_verifier Has to be unhashed value from the previous endpoint used in the parameter code_challenge.
- code The value found in the code query string param from the authorization endpoint.
- username Account username.
- password Account password.
refresh_token Has to be passed if the grant_type is refresh_token. Value used to generate new token.

Example curl call for the grant_type authorization_code

curl -v -X POST -H "Content-Type: application/json" -d '{"username":"user@domain.com","password":"secret","grant_type":"authorization_code","client_id":"your_application_id","redirect_uri":"http://yourdomain.com/somepath","code_verifier":"unhashed_value","code":"generated_code_from_authorize"}' "https://api.napster.com/v2.2/oauth/access_token"

Example curl call for the grant_type refresh_token

curl -v -X POST -H "Content-Type: application/json" -d '{"grant_type":"refresh_token","client_id":"your_applicationid","redirect_uri":"http://yourdomain.com/somepath","refresh_token":"refresh_token"}' "https://api.napster.com/v2.2/oauth/access_token"

Implicit

See what it looks like for a client to integrate 3 legged Oauth with the code sample provided here: https://jsfiddle.net/napstercat/zf0wjup7/

In this flow, your application directs the member (in a Web browser) to a Napster-hosted sign-in form, where she's prompted to authorize your application:

  "https://api.napster.com/oauth/authorize?client_id={api_key}&redirect_uri=http://yourdomain.com/somepath&response_type=code"

An optional state parameter for this request is also supported as described by OAuth RFC 6749.

"https://api.napster.com/oauth/authorize?client_id={api_key}&redirect_uri=http://yourdomain.com/somepath&response_type=code&state={your_state_value}"

If the member accepts your request for authentication, we redirect back to your redirect_uri with a temporary code in the code query parameter. If originally passed in, the state parameter is also returned, unchanged.

http://yourdomain.com/somepath?code={temporary_code}&state={your_state_value}

Then, exchange this code for an access token, using your application secret:

curl -v -X POST -d "client_id={api_key}&client_secret={api_secret}&response_type=code&grant_type=authorization_code&redirect_uri={redirect_uri}&code={temporary_code}" "https://api.napster.com/oauth/access_token"

If the member cancels the authentication in the middle of the OAuth flow, the member is sent back to the redirect_uri with the error, error_reason and error_description parameters describing the error. If originally passed in, the state parameter is also returned, unchanged.

{redirect_uri}?error=access_denied&error_reason=user_denied&error_description=The%20user%20denied%20your%20request.&state={your_state_value}

Password Grant

In this flow, you exchange a member's username and password (which your application obtains directly from the member) for an access token and a refresh token. You can then safely store these two tokens in your application, and use them to make authenticated calls.

curl -v -X POST -u "{api_key}:{api_secret}" -d "username=user@domain.com&password=secret&grant_type=password" "https://api.napster.com/oauth/token"

Access Token Responses

In either flow, you'll receive an access_token and a refresh_token:

{
  "access_token" : "HYGIuQkfWHawATkDSfJC5acAl7ed",
  "refresh_token" : "YUPzO9xC0kfyWq8Vi8OIzpfaPW2PO6x9",
  "expires_in" : "86399"
}

Using these (example) tokens, you can make API requests on the member's behalf — for instance, to obtain the member's listening history, passing the access token value in an Authorization header (of type "Bearer"):

curl -v -H "Authorization: Bearer HYGIuQkfWHawATkDSfJC5acAl7ed" "https://api.napster.com/v2.1/me/listens"

Token Expiration

Access tokens expire regularly, so your application should take steps to refresh them as needed. (Note the expires_in value above, which denotes that the associated token expires in 86399 seconds, or just under 24 hours.) To do so, simply call the access_token service, passing your client secret:

curl -v -X POST -d "client_id={api_key}&client_secret={api_secret}&response_type=code&grant_type=refresh_token&refresh_token={refresh_token}" "https://api.napster.com/oauth/access_token"

Public Member APIs

Public Member APIs provide information that can be accessed without an OAuth access token. Data about members is limited based upon member's visibility settings.

Profile

GET Public Member Avatar

Returns avatar photo information for a member. Endpoint mirrors the /me version of this endpoint. See GET Member Avatar for full details of accepted options.

Authenticated Member APIs

Authenticated Member APIs provide information about Napster members. Any calls to these /me endpoints require OAuth access tokens to access data on behalf of the member. See Authentication Section for details on how to obtain an access token.

Account

GET Member Account Details

Returns information about currently authenticated members account (first and last name, id, email, country, language, phone -if the account has one associated with it-, etc.), subscription (billing partner code, tier and product codes and names, trial information and etc.) and entitlements (information about member's rights, tier and limits).

curl -v  -H "Authorization: Bearer {access_token}" "https://api.napster.com/v2.1/me/account"

Within this returned data, the following must be checked:

Within the subscription key, if either the value of the isSuspended element is true, or the value of the state element is "EXPIRED", you should message the member that there is a problem with their account and direct them to http://www.napster.com if possible.
Within the entitlements key, you must check the canStream* entitlements for your specific integration type (Web, Home Audio Device, etc.) For example, if your integration is for a home audio streaming product, you will need to check to ensure that the value of the canStreamOnHomeDevice element is true. If this is false you cannot permit streaming on the device, should message the member that they need to upgrade their account to use on the device, and direct them to http://www.napster.com if possible.

Favorites

This endpoint has a filter parameter which can be used to retrieve specific favorite types.

curl -v  -H "Authorization: Bearer {access_token}" "https://api.napster.com/v2.1/me/favorites?filter=track"

NOTE: The isStreamableOnly parameter is supported on this endpoint but only in conjunction with the track and album filter parameters. The isStreamableOnly parameter will not be used if one of these filters is not passed as well.

Station Tuning

PUT Apply Station Tuning

Tuning allows the member to customize future station track selection by increasing or decreasing artist Popularity and Variety from 0.0-1.0. A Variety setting of 0.0 means tracks from very few artists will be played, a setting of 1.0 means tracks from many artists will be played, and a setting of 0.5 is half-way between the two. A Popularity setting of 0.0 means only tracks from known artists will be played, a setting of 1.0 means mostly tracks from unknown Artists will be played, and a setting of 0.5 is half-way between the two.

curl -v -X PUT  -H "Authorization: Bearer {access_token}" -H "Content-Type: application/json" -d '{ "tuning": {"popularity" : "0.8", "variety" : "0.2"} }' "https://api.napster.com/v2.1/stations/Tra.54718457/tuning"

Feedback

PUT Submit Station Track Feedback

Feedback allows the member to customize future station track and preview selection by Liking, Disliking, Skipping, etc. station tracks and previews.

The following table shows which feedback actions are valid for each track type.

Action	Track	Preview
play		X
unplay	X
skip	X	X
like	X	X
dislike	X	X
favorite	X	X
unfavorite	X	X

Example

curl -v -X PUT  -H "Authorization: Bearer {access_token}" -H "Content-Type: application/json" -d '{ "tracks": [ { "id":"Tra.1231235" },{ "id":"Tra.2564564" } ] }' "https://api.napster.com/v2.1/stations/art.177922095/feedback/like"

Note that it is highly recommended that clients retrieve only station tracks and not station previews. With station previews, clients must call the station track feedback of "play" as well as the playbackStart and playbackStop metering calls for the tracks played. There is no need to submit "play" feedback for tracks, but the playbackStart and playbackStop events must still be sent for each station track played.

Images

To improve performance of the service, most APIs return light metadata, which, for all but albums, does not contain image URLs. For any items requiring an image, the client should use the imageserver service, which provides deterministic URLs for images that the client can programmatically generate for the target content item.

Napster image server supports jpg images.

If there are specific image sizes required for your implementation please let your Napster representative know for confirmation of support or addition to the service.

Artists

Playlists

GET Get a Playlist Image

Generate a valid request URL for a playlist image. There are no associated images available in metadata for member playlists, so a montage of the playlist’s content items is generated.
