Lean Delivery

Get to market quickly with an MVP.
Learn from users to improve and expand the platform.
Reduce waste, don't build unnecessary stuff.

Managed Services

Administering servers is expensive and time consuming.
Focus on building the product.
Make use of cloud services to handle up time and availability.

Authentication

Oauth2 / OpenID

Phase 1

Use existing identity providers. This removes the need to call a database to store user passwords.

Phase 2

Implement Blocs user management, storing passwords and generating tokens ourselves if needed.

Create a new user

    -H "Authorization: Bearer $TOKEN" \
    'https://api.focusrite.com/user/{userId}/purchases'

Downloading Content

Blocs API Downloads

Cloud front

S3

curl -X GET \
    -H "Authorization: Bearer $TOKEN" \
    "https://api.focusrite.com/pack/{packId}/token"

# 302 Redirect
# Location: https://downloads.focusrite.com/pack/{packId}?token=cGFja0lkPTIzNDU1NTUzNDQ0Cg==

Get a download token for the pack

This endpoint checks whether the user has purchased the pack and returns a redirect to the download endpoint with a token containing the pack ID and an expiry time. This token is signed using a private key.

Example flow: downloading a purchased pack

curl "https://downloads.focusrite.com?token=cGFja0lkPTIzNDU1NTUzNDQ0Cg=="

Download the pack

Token is checked on the CDN, if valid, it tries to deliver the content from one of its cached nodes, otherwise, it streams it from S3 into its cache for use next time and out the the user.
