Before you start your application...

1. You have to:
   • have Strava account and some activities on it
   • set up your API app in Strava
   • and then get client_id and client_secret
2. Then use browser and following links to get access and refresh tokens:
   Manually in browser (put appropriate data when in CAPITALS):
   • https://www.strava.com/oauth/authorize?client_id=YOUR_CLIENT_ID&redirect_uri=http://localhost&response_type=code&scope=activity:read_all
     This will open Strava authorization page. Click authorize. This will in turn open page:
   • http://localhost/?state=&code=SOMECODE&scope=read,activity:read_all
     Get somecode and put it in POST request: POST request:
   • https://www.strava.com/oauth/token?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&code=SOMECODE_FROM_PREVIOUS_STEP&grant_type=authorization_code
3. from response get: refresh_token and access_token

Put your client_id, client_secret and obtained in previous steps access_token and refresh_token in token.yaml file. It should look like this:

client_id: 'xxxxx'
client_secret: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
refresh_token: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
access_token: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
grant_type: 'refresh_token'
f: 'json'

Now you can get your activities from Strava.
getLoggedInAthleteActivities

access_token could be used directly by it expires so refresh_token is used to get new access token.

Deployment

Since Heroku is no longer offering free dynos deployment was moved to Render.
But files necessary for Heroku deployment haven't been removed (Procfile, runtime.txt).
!!! All necessary files for deployment are included but don't forget to remove token.yaml and redis.yaml from .gitignore!!!
