REST API

This page introduces you to using and consuming Canopy’s REST API.

Why REST?

Modern web applications are often based on separating the front-end UI code and the back-end services, and ensuring proper communication using the various HTTP methods as they were intended for. Canopy adopts a (mostly) REST based approach to its own API, and we are happy for our users to develop against our API. This provides a language-agnostic way of integrating with Canopy, as an alternative to using the python interface (see Writing plugins).

Our API is stable in the sense that we try to avoid breaking changes where possible. Advanced warning will be provided where breaking changes are likely to occur to allow our users to determine the impact against their own API integrations. However, if we find that we need to make more frequent API changes in the future, we will fork development of a more stable API-specific server which will be preferred over our internal API.

Authentication

Currently, we can support the following authentication types:

We recommend that all communications with the API server be conducted over HTTPS.

Todo

Add section for Basic auth?

Token based authentication

Token authentication uses a header field containing a token to authenticate API users on a per call basis (the token must be included in each API call). Each user in Canopy can have a single token associated with them that allows access with their privileges. The token does not expire.

To generate a token for a user execute the following on the Canopy server as the canopy user:

canopy-manage drf_create_token USER_EMAIL_ADDRESS

This will generate a 40 character alphanumeric token which can be used to perform API actions for the associated user.

For token based authentication the Authorization HTTP header should have the value Token GENERATED_TOKEN.

Header field name: Authorization

Header field value: Token<SPACE><GENERATED_TOKEN>

Putting them together, an example HTTP header looks like this: Authorization: Token 2cdd70527c03ac18be79fc6a56ab11f857bd2ad9

Example usage via curl to retrieve the list of companies:

curl -v -X GET https://CANOPY/api/company/company/ -H 'Authorization: Token 2cdd70527c03ac18be79fc6a56ab11f857bd2ad9'

Example usage via Python and the requests library:

import requests

res = requests.get(
    'http://127.0.0.1:8000/api/company/company/',
    headers=dict(
        Authorization='Token 2cdd70527c03ac18be79fc6a56ab11f857bd2ad9'
    )
)
print res.json()

Unlike user-based session authentication, no CSRF token or session ID is required for token based authentication.

Demo API integration

A demo API client is available here: demo_api_client.py

API reference

Canopy ships with a browsable API interface, which is self documenting and provides test forms for invoking different API methods (GET, POST, PUT, DELETE, etc., depending on the permissions of the user).

You can enable the browsable API interface by adding the following configuration line to /etc/canopy/canopy.ini:

ENABLE_API_BROWSER=1

And then restarting Canopy:

systemctl restart canopy

Warning

This configuration is NOT recommended for production use.

Canopy’s API is grouped into a set of top-level roots, with each one providing access to a number of related sub-sections.

API root Sub-sections Description
/health/ N/A A simple health check for back-end services.
/api/activities/

/api/accounts/
  • custom_roles
  • permissions
  • profile
  • skills
  • allgrants
  • status
  • user
  • accesscontrol

Accounts gives the user access to certain information relating to users, roles, and other account information (authentication, authorisation, etc.) on the system. This data is restricted based on the user’s permissions. For example, a standard user can list user account information. However, they cannot modify it.
