Microsoft Outlook Calendar Overview#

The Microsoft Outlook Calendar API provides programmatic access to a user's calendar events, allowing for the creation, retrieval, update, and deletion of events within Outlook calendars. With Pipedream, you can integrate these calendar operations into workflows that automate tasks involving scheduling, event management, and coordination with other services. Whether it's triggering actions when new events are created, syncing calendar events with other scheduling tools, or managing attendees, Pipedream's serverless platform enables you to build custom automations with minimal overhead.

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
Microsoft Outlook Calendar	`microsoftOutlook`	`app`	This component uses the Microsoft Outlook Calendar app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`
Minutes Before	`minutesBefore`	`integer`	Number of minutes to trigger before the start of the calendar event.

Trigger Authentication#

Microsoft Outlook Calendar uses OAuth authentication. When you connect your Microsoft Outlook Calendar account, Pipedream will open a popup window where you can sign into Microsoft Outlook 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 Microsoft Outlook Calendar API.

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

User.Reademailoffline_accessopenidprofileCalendars.ReadWrite

Node Overview#

Develop, run and deploy your Node.js code in Pipedream workflows, using it between no-code steps, with connected accounts, or integrate Data Stores and File Stores

This includes installing NPM packages, within your code without having to manage a package.json file or running npm install.

Below is an example of installing the axios package in a Pipedream Node.js code step. Pipedream imports the axios package, performs the API request, and shares the response with subsequent workflow steps:

Action Code#

import node from "../../node.app.mjs";

export default {
  name: "Run Node Code",
  version: "0.0.3",
  annotations: {
    destructiveHint: false,
    openWorldHint: true,
    readOnlyHint: false,
  },

  },
  type: "action",
  methods: {},
  async run({
    steps, $,
  }) {
    // Return data to use it in future steps
    return steps.trigger.event;
  },
};

Action Configuration#

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

Label	Prop	Type	Description
Node	`node`	`app`	This component uses the Node app.

Action Authentication#

The Node API does not require authentication.

About Node#

Anything you can do with Node.js, you can do in a Pipedream workflow. This includes using most of npm's 400,000+ packages.
