What's Cozy?

What's this new konnector?

If you want to work on this konnector and submit code modifications, feel free to open pull-requests! See the [contributing guide][contribute] for more information about how to properly open pull-requests.

Test the connector without an accessible cozy-stack

If you just want to test this connector without any cozy available.

You first need an installed nodejs (LTS version is fine).

We also suggest you tu use yarn instead of npm for node packages.

npm install --global yarn

Then just run :

yarn standalone

The requests to the cozy-stack will be stubbed using the [./data/fixture.json] file as source of data and when cozy-client is asked to create or update data, the data will be output to the console. The bills (or any file) will be saved in the ./data directory.

Run the connector linked to a cozy-stack

If you do not want to have to install the konnector on a cozy v3 to test it, you can register the konnector as an OAuth application with the following commands :

yarn dev

This command will register your konnector as an OAuth application to the cozy-stack. By default, the cozy-stack is supposed to be located in If this is not your case, just update the COZY_URL field in [./data/env.js].

After that, your konnector is running but should not work since you did not specify any credentials to the target service. You can do this in a [./data/env_fields.json] (you have [./data/env_fields.json.template] available as a template)

Now run yarn dev one more time, it should be ok.

How does the cozy-stack run the connector ?

The cozy-stack runs the connector in a rkt container to be sure it does not affect the environment.

The connector is run by calling npm start with the following envrionment variables :

  • COZY_CREDENTIALS needs to be the result of cozy-stack instances token-cli <instance name> <scope>
  • COZY_URL is the full http or https url to your cozy
  • COZY_FIELDS is something like :

The "account" field is the id of the record with doctype "io.cozy.accounts" which will be used as parameters for your konnector.


To be able to run the connector, the cozy stack needs a connector which is built into only one file, without needing to npm install it, this will be a lot faster to install.

There is a command in package.json to help you to do that : yarn build

This command uses webpack to bundle all the code needed by your connector into one file.

This will generate an index.js file in the build directory. The expected way to deploy this built file is to create a 'build' branch (or with another name)

yarn build
git checkout -b build   # if the build branch does not exist yet
cp build/index.js ./
git add index.js
git ci -m "built"
git push origin build

And your konnector can now be installed using the following url :
