Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Google Calendar Overview#

The Google Calendar API gives developers access to Google Calendar data,
allowing them to create their own applications that can read, write, and update
calendar data. With the API, users can integrate their own calendar
applications with Google Calendar, giving them the ability to manage their
calendars in one place. The API also provides the ability to search for events
and create new events.

Possible applications that could be built using the Google Calendar API
include:

A calendar application that integrates with Google Calendar, allowing users
to manage their calendars in one place.
A calendar application that allows users to search for events and create new
events.
A to-do list application that integrates with Google Calendar, allowing users
to see their tasks and events in one place.
A reminder application that uses Google Calendar data to remind users of
upcoming events.

Trigger Code#

import common from "../common.mjs";

export default {
  ...common,
  key: "google_calendar-event-cancelled",
  name: "Event Cancelled",
  description: "Emits when an event is cancelled or deleted",
  version: "0.1.2",
  type: "source",
  dedupe: "unique", // Dedupe events based on the Google Calendar event ID
  methods: {
    ...common.methods,
    getConfig({
      intervalMs, now,
    }) {
      const updatedMin = new Date(now.getTime() - intervalMs).toISOString();
      return {
        calendarId: this.calendarId,
        updatedMin,
        showDeleted: true,
        singleEvents: true,
        orderBy: "startTime",
      };
    },
    isRelevant(event) {
      return event.status === "cancelled";
    },
  },
};

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Google Calendar	`googleCalendar`	`app`	This component uses the Google Calendar app.
Calendar ID	`calendarId`	`string`	Select a value from the drop down menu.
	`timer`	`$.interface.timer`

Trigger Authentication#

Google Calendar uses OAuth authentication. When you connect your Google Calendar account, Pipedream will open a popup window where you can sign into Google Calendar and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Google Calendar API.

Pipedream requests the following authorization scopes when you connect your account:

emailprofilehttps://www.googleapis.com/auth/calendar.eventshttps://www.googleapis.com/auth/calendar.readonlyhttps://www.googleapis.com/auth/calendar.settings.readonly

Slack Overview#

The Pipedream Slack app enables you to build event-driven workflows that interact with the Slack API. When you authorize the Pipedream app's access to your workspace, you can use Pipedream workflows to perform common Slack actions, or write your own code against the Slack API.

The Pipedream Slack app is not a typical app. You don't interact with it directly as a bot, and it doesn't add custom functionality to your workspace out of the box. It just makes it easier to automate anything you'd typically use the Slack API for, using Pipedream workflows.

Here are some examples of automations you can build with Pipedream on Slack:

Automate posting updates to your team channel
Create a bot to answer common questions
Integrate with your existing tools and services
Build a custom dashboard to track your team's progress
Create a bot to handle scheduling and meeting requests
And much more!

Should I use the Slack or Slack Bot app on Pipedream?

The Slack app is the easiest and most convienent option to get started. It installs the official Pipedream bot into your Slack workspace with just a few clicks.

However, if you'd like to use your own bot registered with the Slack API, you can use the Slack Bot app instead.

The Slack Bot requires a bot token to allow your Pipedream workflows to authenticate as your bot. The extra set up steps allow you to list your custom bot on the Slack Marketplace, or install the bot on other workspaces as your bot's name instead of as Pipedream.

Getting Started

You can install the Pipedream Slack app in the Accounts section of your account, or directly in a workflow

Accounts

Visit https://pipedream.com/accounts.
Click on the Click Here To Connect An App button in the top-right.
Search for "Slack" among the list of apps, and select it.
This will open a new window asking you to allow Pipedream access to your Slack workspace. Choose the right workspace where you'd like to install the app, then click Allow.
That's it! You can now use this Slack account in any actions, or link it to any code step.

Within a workflow

Create a new workflow.
Select your trigger (HTTP, Cron, etc.).
Click on the + button below the trigger step, and search for "Slack".
Select the Send a Message action.
Click the Connect Account button near the top of the step. This will prompt you to select any existing Slack accounts you've previously authenticated with Pipedream, or you can select a New account. Clicking New opens a new window asking you to allow Pipedream access to your Slack workspace. Choose the right workspace where you'd like to install the app, then click Allow.
That's it! You can now connect to the Slack API using any of the Slack actions within a Pipedream workflow.
