Withings to Garmin Connect – resurrection

Go to to download the script.

  • SSO authorization derived from

Obtaining Withings Authorization Code

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

$ ./ -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 (


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 URI

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

    "callback_url": "",
    "client_id": "183e0******0b3551f96765c98c1******b64bbbaf491626",
    "consumer_secret": "a75d65******1df1514c16719ef7bd69fa7*****2e2b0ed48f1765"
