Download all your Foursquare checkins with Python.

export_foursquare_checkins.py

# pip install requests
import requests
import json
 
url_template = 'https://api.foursquare.com/v2/users/self/checkins?limit=250&oauth_token={}&v=20131026&offset={}'
 
# If you navigate to https://developer.foursquare.com/docs/explore, Foursquare
# will generate an OAuth token for you automatically. Cut and paste that token
# below.
token = ""
offset = 0
data = []
 
with open("/tmp/checkins.json", 'w') as f:
    while True:
        response = requests.get(url_template.format(oauth_token, offset))
        if len(response.json()['response']['checkins']['items']) == 0:
            break

        data.append(response.json())
        offset += 250
            
    f.write(json.dumps(data))

After you create an app, you must fill the "REDIRECT URL" in the app settings (arbitrary).

Then you should open the following link in the browser:

"https://foursquare.com/oauth2/authenticate?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI" (replace YOUR_CLIENT_ID and YOUR_REGISTERED_REDIRECT_URI with app id and redirect url).

After that, you are redirected to the auth page. Allow the app to use your data, then you will be redirected to

"https://YOUR_REGISTERED_REDIRECT_URI/?code=CODE". The code is needed for obtaining the auth token.

You add

r= 'https://foursquare.com/oauth2/access_token?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=authorization_code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI&code=CODE'

req = requests.get(r)
req.json()

This will print out the oauth code for the script above.
