Withings to Garmin Connect – resurrection

After dropping “legacy” APIs on Withings page, the script stopped to work…

It took quite a while to adjust it to OAuth2 but finally – it’s done!

Go to https://github.com/jaroslawhartman/withings-garmin-v2 to download the script.


  • Based on withings-garmin by Masayuki Hamasaki, improved to support SSO authorization in Garmin Connect 2.
  • SSO authorization derived from https://github.com/cpfair/tapiriik


$ sudo easy_install requests

$ sudo easy_install simplejson


Usage: $python sync.py [options]

  -h, --help            show this help message and exit
  --garmin-username=<user>, --gu=<user>
                        username to login Garmin Connect.
  --garmin-password=<pass>, --gp=<pass>
                        password to login Garmin Connect.
  -f <date>, --fromdate=<date>
  -t <date>, --todate=<date>
  --no-upload           Won't upload to Garmin Connect and output binary-
                        string to stdout.
  -v, --verbose         Run verbosely

Obtaining Withings Authorization Code

When running for a very first time, you need to obtain Withings authorization:

$ ./sync.py -f 2019-01-25 -v
Can't read config file config/withings_user.json
*         W A R N I N G               *

User interaction needed to get Authentification Code from Withings!

Open the following URL in your web browser and copy back the token. You will have *30 seconds* before the token expires. HURRY UP!
(This is one-time activity)


Token : _

You need to visit the URL listed by the script and then – copy Authentification Code back to the prompt.

This is one-time activity and it will not be needed to repeat.


You can hardcode your usernames and passwords in the script (sync.py):


For advanced users – registering own Withings application

The script has been registered as a Withings application and got assigned Client ID and Consumer Secret. If you wish to create your own application – feel free!

Note, registering it is quite cumbersome, as you need to have a callback URL and an Icon. Anyway, when done, you should have the following identifiers:

Client ID183e03.................765c98c10e8f1aa647a37067a1......baf491626
Consumer Secreta75d65.................4c16719ef7bd69fa7c5d3fd0ea......ed48f1765
Callback URIhttps://jhartman.pl/withings/notify

Configure them in config/withings_app.json, for example:

    "callback_url": "https://wieloryb.uk.to/withings/withings.html",
    "client_id": "183e0******0b3551f96765c98c1******b64bbbaf491626",
    "consumer_secret": "a75d65******1df1514c16719ef7bd69fa7*****2e2b0ed48f1765"

Fix for “Withings to Garmin Connect” authorisation problems

It has been reported that the script does not work anymore:

jhartman@wieloryb:~/scripts/withings-garmin-v2$ ./sync.py
Traceback (most recent call last):
  File "./sync.py", line 124, in <module>
  File "./sync.py", line 59, in main
  File "./sync.py", line 116, in sync
    cookie = garmin.login(garmin_username, garmin_password)
  File "/home/jhartman/scripts/withings-garmin-v2/garmin.py", line 132, in login
    cookies = self._get_cookies(email=username, password=password)
  File "/home/jhartman/scripts/withings-garmin-v2/garmin.py", line 100, in _get_cookies
    data["lt"] = re.search("name=\"lt\"\s+value=\"([^\"]+)\"", preResp.text).groups(1)[0]
AttributeError: 'NoneType' object has no attribute 'groups'

I’ve managed to fix it. See latest commit in https://github.com/jaroslawhartman/withings-garmin-v2

Withings to Garmin Connect

Since a while I’m owning great Withings Scale which has a capability to store measurements in a cloud. Because I’m using Garmin GPSes (and Garmin Connect), I’d love to synchronize the measurements to the Garmin Connect site.

Lucky, I found a great script garmin-withings.

Unfortunately, after latest changes in the Garmin Connect (implementation of SSO on march 2014) the script stopped to work. I’ve compiled changes proposed by https://github.com/cpfair/tapiriik and it seems that the script with my updates works again (well, at least until further changes in Garmin Connect…)

You can find the script on https://github.com/jaroslawhartman/withings-garmin-v2


Garmin Connect can display a lot of other parameters, not only weight and body fat level:


It would be great to calculate all these figures and post them to Garmin Connect, right? 🙂
