Kopano API

Kopano API provides a web service with the endpoints to interface with Kopano via HTTP APIs. The availability of APIs is controlled by plugins. See the Plugins section below for details.

Technologies

• Go

Build dependencies

Make sure you have Go 1.13 or later installed. This project uses Go modules.

Building from source

git clone <THIS-PROJECT> kapi
cd kapi
make

Build with Docker

docker build -t kapid-builder -f Dockerfile.build .
docker run -it --rm -u $(id -u):$(id -g) -v $(pwd):/build kapid-builder

Running Kopano API

KOPANO_GRAPI_SOCKETS=/run/kopano-grapi ./bin/kapid serve \
  --listen 127.0.0.1:8039 \
  --plugins-path=./plugins \
  --plugins=grapi \
  --iss=https://mykonnect.local

Where --plugins-path points to a folder containing Kopano API plugin modules. Add environment variables as needed by those plugins. See next chapter for more information about plugins.

The --plugins parameter can be used to select what plugins should be enabled. It takes a comma separated value of plugin IDs as the plugin defined it during its build time. If the --plugins parameter is empty (the default), all plugins found will be activated.

The --iss parameter points to an OpenID Connect issuer with support for discovery (Kopano Konnect). On start, the service will try discover OIDC details and allow Bearer authentication with access tokens once successful. The --iss parameter is mandatory.

Plugins

Kopano API supports plugins to its behavior and ships with a bunch of plugins to provide API endpoints from various data sources and different purposes. An example plugin can be found in plugins/example-plugin.

grapi: Kopano Groupware REST plugin (GRAPI)

Kopano API includes the plugin for Kopano Groupware REST. This plugin provides access to Kopano Groupware RESTful API via /api/gc/ URL routing prefix.

To specify where the grapi plugin can find its required GRAPI backend sockets, specify the KOPANO_GRAPI_SOCKETS environment variable to point to the base directory location. All rest*.sock files in that directory will be used as upstream proxy paths for the REST api and all notify*.sock files in that directory will be used as upstream proxy paths for the subscription socket API.

See the grapi plugin README for further details.

pubs: Kopano Pubsub and Webhook plugin

Kopano API includes a pub/sub system and webhook system via the Pubs plugin, routed to the /api/pubs URL routing prefix. To specify the cryptographic secret for the Pubs plugin use the environment variable KOPANO_PUBS_SECRET_KEY. For more information on the Pubs plugin look at 'plugins/pubs/README.md'.

See the pubs plugin README for further details.

kvs: Kopano Key Value Store plugin

Kopano API inclues a key value store via the kvs plugin, routed to the /api/kvs URL routing prefix. Kvs plugin needs configuration for its persistent storage layer. Look at 'plugins/kvs/README.md' for more information.

See the kvs plugin README for further details.

Run unit tests

make test

Testing the Kopano API

To test, some prerequisites are needed. A full fledged setup with TLS web server, authentication provider and backend is strongly suggested. An quick way to set this up is using a Kopano Docker environment which provides:

• TLS web server with Kopano Web,
• Authentication with Kopano Konnect
• Backend with GRAPI and Kopano Groupware

Once you have all the bits in place and set up correctly, look at the test folder in this project for a bunch of scripts and helpers to simplify testing and give you ideas how to access the APIs provided by kapi.
