Send Smart Action notifications to Slack

This example shows you how to integrate Slack incoming webhooks to receive notifications in your workspace when a Smart Action e.g "Reject application" is triggered.

Demo

Create your Forest Admin slack app

Follow Slack's guide to create a new app in your workspace and start sending messages using Incoming Webhooks.

At the end of this guide, make sure your Slack app has the following features activated:

  • Incoming Webhooks

  • Interactive Components

  • Bots

  • Permissions

Once your Slack app has its shiny Incoming Webhook URL, you will be able to send your message in JSON as the body of an application/json POST request.

https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX

Connect your app from a Slack channel of your choice

From the channel, visi

Set up the webhook from your admin backend

Install the node.js Slack SDK

From your project's directory, simply run

$ npm install --save @slack/webhook

Add the Incoming Webhook URL to your .env

SLACK_WEBHOOK_URL=https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX

This Incoming Webhook URL contains a secret key, please make sure it does not appear in your code.

Create the Smart Action and initialize the Incoming Webhook

Smart Action declaration

forest/companies.js
const { collection } = require('forest-express-sequelize');
// This file allows you to add to your Forest UI:
// - Smart actions: https://docs.forestadmin.com/documentation/reference-guide/actions/create-and-manage-smart-actions
// - Smart fields: https://docs.forestadmin.com/documentation/reference-guide/fields/create-and-manage-smart-fields
// - Smart relationships: https://docs.forestadmin.com/documentation/reference-guide/relationships/create-a-smart-relationship
// - Smart segments: https://docs.forestadmin.com/documentation/reference-guide/segments/smart-segments
collection('companies', {
actions: [{
name: 'Reject application',
type: 'single',
fields: [
{
field: 'Reason(s) for rejection',
description: 'Please provide a reason for this decision',
type: ['Enum'],
enums: ['Certificate of Incorporation', 'Proof of Address ID', 'Bank Statement ID'],
required: true,
},
{
field: 'Comment',
description: 'This comment will only be displayed in your slack workspace message',
type: 'String',
widget: 'text area',
},
],
}],
// ...
});

Smart Action logic

routes/companies.js
const express = require('express');
const { PermissionMiddlewareCreator, RecordsGetter } = require('forest-express-sequelize');
const { IncomingWebhook } = require('@slack/webhook');
const { companies } = require('../models');
const router = express.Router();
const permissionMiddlewareCreator = new PermissionMiddlewareCreator('companies');
const url = process.env.SLACK_WEBHOOK_URL;
// This file contains the logic of every route in Forest Admin for the collection companies:
// - Native routes are already generated but can be extended/overriden - Learn how to extend a route here: https://docs.forestadmin.com/documentation/v/v6/reference-guide/routes/extend-a-route
// - Smart action routes will need to be added as you create new Smart Actions - Learn how to create a Smart Action here: https://docs.forestadmin.com/documentation/v/v6/reference-guide/actions/create-and-manage-smart-actions
// ...
// Initialize webhook
const webhook = new IncomingWebhook(url);
router.post('/actions/reject-application', permissionMiddlewareCreator.smartAction(), async (request, response) => {
// Get input form attributes
const attributes = await request.body.data.attributes.values;
const rejectionReason = attributes['Reason(s) for rejection'];
const comment = attributes['Comment'];
// Get selected company
const [selectedCompanyId] = await new RecordsGetter(companies).getIdsFromRequest(request);
const selectedCompany = await companies.findByPk(selectedCompanyId);
// Change company status to rejected
await companies.update({ status: 'rejected' }, { where: { id: selectedCompanyId } })
response.send({ success: 'Company\'s request to go live rejected!' });
// Trigger Slack webhook
await webhook.send({
text: 'An action has been triggered from Forest Admin',
channel: 'C01CFGCADGF', // replace by your Slack channel ID
blocks: [

},
