  --no-upload           Won't upload to Garmin Connect or TrainerRoad.
  --verbose, -v         Run verbosely

Providing credentials via environment variables

You can use the following environment variables for providing the Garmin and/or Trainerroad credentials:

GARMIN_USERNAME
GARMIN_PASSWORD
TRAINERROAD_USERNAME
TRAINERROAD_PASSWORD

Providing credentials via secrets files

You can also populate the following 'secrets' files to provide the Garmin and/or Trainerroad credentials:

/run/secrets/garmin_username
/run/secrets/garmin_password
/run/secrets/trainerroad_username
/run/secrets/trainerroad_password

Secrets are useful in an orchestrated container context — see the Docker Swarm or Rancher docs for more information on how to securely inject secrets into a container.

Order of priority for credentials

In the case of credentials being available via multiple means (e.g. environment variables and secrets files), the order of resolution for determining which credentials to use is as follows, with later methods overriding credentials supplied by an earlier method:

Read secrets file(s)
Read environment variable(s)
Use command invocation arugment(s)

Obtaining Withings Authorization Code

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

$ withings-sync -f 2019-01-25 -v
Can't read config file config/withings_user.json
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)

https://account.withings.com/oauth2_user/authorize2?response_type=code&client_id=183e03e1f363110b3551f96765c98c10e8f1aa647a37067a1cb64bbbaf491626&state=OK&scope=user.metrics&redirect_uri=https://wieloryb.uk.to/withings/withings.html&

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.

Tips

Garmin SSO errors

Some users reported errors raised by the Garmin SSO login:

withings_sync.garmin.APIException: SSO error 401

withings_sync.garmin.APIException: SSO error 403

These errors are raised if a user tries to login too frequently. E.g. by running the script every 10 minutes.

We recommend to run the script around 8-10 times per day (every 2-3 hours).

Docker

$ docker pull ghcr.io/jaroslawhartman/withings-sync:master

First start to ensure the script can start successfully:

Obtaining Withings authorisation:

$ docker run -v $HOME:/root --interactive --tty --name withings ghcr.io/jaroslawhartman/withings-sync:master --garmin-username=<username> --garmin-password=<password>

Token : <token>
Withings: Get Access Token
Withings: Refresh Access Token
Withings: Get Measurements
   Measurements received
JaHa.WAW.PL
Garmin Connect User Name: JaHa.WAW.PL
Fit file uploaded to Garmin Connect

And for subsequent runs:

$ docker start -i withings
Withings: Refresh Access Token
Withings: Get Measurements
   Measurements received
JaHa.WAW.PL
Garmin Connect User Name: JaHa.WAW.PL
Fit file uploaded to Garmin Connect

Run a periodic Kubernetes job

Edit the credentials in contrib/k8s-job.yaml and run:

$ kubectl apply -f contrib/k8s-job.yaml

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!

First you need a Withings account. Sign up here.
Then you need a a Withings developer app registered. Create your app here.

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:

Identfier	Example
Client ID	`183e03.................765c98c10e8f1aa647a37067a1......baf491626`
Consumer Secret	`a75d65.................4c16719ef7bd69fa7c5d3fd0ea......ed48f1765`
Callback URI	`https://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"
}

For the callback URL you will need to setup a webserver hosting contrib/withings.html.
