Glue API authentication and authorization

Spryker’s Glue API uses the OAuth 2.0 framework for authentication to secure its resources. On a technical level, this is handled by the Login API. To gain access to a protected resource, a client application must first obtain an access token. This token, a JSON Web Token (JWT), identifies the user in subsequent API calls and must be included in the request header.

Access and refresh tokens

For security, access tokens have a limited lifespan. The default lifetime is 8 hours (28,800 seconds). When an access token is issued, the response also includes a refresh token.

• Access Token: Used to authenticate requests to protected resources.
• Refresh Token: When an access token expires, the refresh token can be exchanged for a new access token and a new refresh token. The default lifetime for a refresh token is 1 month (2,628,000 seconds).

It is recommended to revoke refresh tokens when they are no longer needed or if they become compromised. A revoked token is immediately marked as expired and cannot be used to obtain a new access token.

Accessing protected resources

To make a request to a protected resource, you must pass the access token in the Authorization header.

Example Request:

GET /carts HTTP/1.1
Host: mysprykershop.com:10001
Content-Type: application/json
Authorization: Bearer eyJ0...
Cache-Control: no-cache

If the token is valid, the API will process the request. If authorization fails, the API returns a 401 Unauthorized error with a code explaining the reason for the failure.

Example Error Response:

{
    "errors": [
        {
            "detail": "Invalid access token.",
            "status": 401,
            "code": "001"
        }
    ]
}

User and application types

Authentication grants access based on user type, and different endpoints may require different user roles. In the Spryker ecosystem, there is a distinction between the Storefront and Backend APIs.

• Storefront API: Used to authenticate a customer.
• Backend API: Used to authenticate a user (for example a company user or agent).

By default, you can authenticate as a customer, a company user, or an agent assist.

Default protected resources

Protected resources require authentication before access is granted. The following table lists the default protected resources. However, since Glue API is highly customizable, we recommend retrieving the specific list of protected resources for your shop.
