Slack - Harvest integration

The project aims to create a standalone application for automated integration between Harvest time tracking tool and Slack messaging system that will notify all configured team users about the amount of time they've spent on each project according to their Harvest timesheet.

Setup

To download the application, check it out with git. Next thing to do is installing all dependencies with the npm node packages manager tool.

$ cd /path/to/project
$ npm install

Next thing to do is preparing the config file. The file must be located in the repository root and named config.json A template file is stored in config.dist.json. The file is divided into sections containing particular configuration options for the application middlewares. To get the Slack <-> Harvest part communicate, the most important thing is to set up the credentials for both services properly.

Architecture

The application is written 100% in Node.JS and at this point consists of three blocks:

• the cron-like time schedule that sends notification messages to slack users,
• a simple HTTP API to trigger notifications (single user and all users notifications, management report),
• a Slack Command API endpoint that manages Harvest timer setup.

###HARVEST configuration

For the moment, harvest communication may be only set up using an account. To have a complete list of projects in all user notifications, an account with access to prefferably all available projects, users and clients should be used. Mandatory parameters in the configuration object are subdomain, email and password.

"harvest": {
    "subdomain": "example_harvest_domain",
    "email": "[email protected]",
    "password": "XXXXXXXXXXXXXXX"
}

###SLACK configuration

The Slack part uses a simple incoming WebHook that needs to be created within the Slack application itself (See https://api.slack.com/incoming-webhooks). The only mandatory parameter that need to be set is endpoint which is the webhook endpoint. The configuration below contains additional params which are overriding the default settings for the webhook. All params available for the webhook can be used except channel, which will always be overridden by slack username of the user that receives the notifications.

"slack": {
    "username": "Harvest",
    "icon_url": "https://avatars0.githubusercontent.com/u/43635?v=3&s=200",
    "endpoint": "XXXXXXXXXXXXXX"
}

Users configuration

The users section contains the mapping of all available users Harvest ID -> Slack username map. Only these users will be available for notification.

"users": {
    "123456": "slack_name"
}

##CRON

For the moment the application is able to:

• notify defined users at the configured time every work day (monday - friday). The time is defined in the cron.notify section of the config file and uses the same timezone as the machine the app is running on. For the configuration below, the app will automatically send notifications every working day at 16:30. If a cron.notify.cronTime value is provided in the config, this value will be used instead of the hour and minutes settings

• refresh (preload) the information about timesheet related entries (clients and projects) according to cron time provided in cron.preload.cronTime section

• send periodical report notifications on Slack management channel defined in cron.report.channel setting according to cron time provided in cron.report.cronTime section

• send reminder messages via Slack to people who have no timers running according to cron.remind.cronTime setting.

"cron": {
    "notify": {
        "hour": "16",
        "munutes": "30",
        "cronTime": "00 30 16 * * 1-5" // Optional, instead of hour/minutes
    },
    "preload": {
        "cronTime": "00 00 7-20 * * 1-5"
    },
    "report": {
        "reportTitle": "Weekly activity report",
        "channel": "#channel_name",
        "cronTime": "00 00 20 * * 5"
    }
}

If any of the section for cron settings are not provided, the cron job will not be set up.

##API

The API provides given endpoints:

• http|https://your.domain.you/notify-all Notifies all users present in the users config providing information about their started tasks.

• http|https://your.domain.you/notify-user/user_id Notifies user given by user_id which represents either Harvest user ID or Slack username about her/his started tasks.

• http|https://your.domain.you/notify-management Notifies management channel provided in the channel property of the POST request.

• http|https://your.domain.you/remind-all Triggers notifications to users wo have no tasks started on Harvest.

The notify-all and notify-user are actions names; this will be useful when creating authorization token.

###API configuration

The api.auth section of the config file contains settings for the authorization parameters. There are two built in methods of authorization:

• Static token method - will be used if an api.auth.token setting is present. The incoming requests will be checked if they contain a POST value with the name token and if the value matches the api.auth.token value.

• Dynamic token method - will be used if an api.auth.secret setting is present. To validate the request and grant access, a POST payload must contain a token and a seed. The token is generated with an SHA1 hash of the same secret as provided in the application config file, seed and the action name from the URL (see above) joined by |.

Example PHP implementation of the token generation:

<?php

$url = "http://some-domain.com/notify-all";
$secret = "thisisthesecret";     // Same secret as in the config file
$seed = generateRandomSeed(10);  // Eg. method that generates random string
$token = sha1(implode("|", array(
	$secret,
    $seed,
    "notify-all"
)));

##Harvest timer management

The app provides an endpoint for a Slack slash command that enables management of the Harvest day entries directly from Slack. The command needs to be configured according to Slack slash command configuration guide https://api.slack.com/slash-commands. The timer management, in the most advanced case, works as a dialogue between the user (via Slack UI) and the server.

###Command syntax

The command syntax contains the configured slack command name (e.g. /timer) and following action name. Available actions:

• status shows the Harvest client, project and task name for the current user task. This is a single step task that doesn't follow a dialogue with the server.

• projects lists out all currently available projects with the client names.

• stop stops the work for the task that is currently running for given user. This is a single step task that doesn't follow a dialogue with the server.

• remind checks all users timelines and sends slack reminder message to all users who have empty day entries timelines. Accepts one additional parameter, which is the userId (either slack name or harvest id).

• start aims to start a task. As an additional param, a project/client name can be provided. This will trigger a dialogue with the server that can be stopped at any point.

• update allows user to update her/his number of hours for given day entry. As an additional param, a project/client name can be provided. This will trigger a dialogue with the server that can be stopped at any point.
