Getting started with Nylas Scheduler

In this tutorial, you'll learn how to install the Scheduler UI Components and set up Nylas Scheduler.

Before you begin

Before you start using the Scheduler UI Components, complete the following tasks:

  1. Sign up for a Nylas account.
  2. Sign in to the v3 Dashboard and create a Nylas application.
  3. Generate an API key for your application and save it.
  4. Authenticate an end user grant.

Install Scheduler UI Components

There are two ways to add Scheduler: using Web components (HTML/Vanilla JS) or React.

  • To use the Scheduler UI Component as Web components, include the CDN package links in your project. You should use a specific version to ensure stability.
  • To install the Scheduler UI Components as React components, install the npm package. The npm package includes both the Scheduling Component and the Scheduler Editor Component.

You can use the @latest tag to pull the latest version for demo purposes and quick testing. However, you should pin to a specific version when developing for production so you can control behavior and consistency. The links below include the Scheduler UI components at a specific version, rather than using the latest version.

<!--Scheduling Component-->
https://cdn.jsdelivr.net/npm/@nylas/web-elements@1.1.4/dist/cdn/nylas-scheduling/nylas-scheduling.es.js

<!--Scheduler Editor Component-->
https://cdn.jsdelivr.net/npm/@nylas/web-elements@1.1.4/dist/cdn/nylas-scheduler-editor/nylas-scheduler-editor.es.js    
npm install @nylas/react@latest

Use Scheduler UI Components in your project

The following examples show how you can include the Scheduling Component in your project.

<html>
  <body>
    <nylas-scheduling></nylas-scheduling>

    <script type="module">

      import { defineCustomElement } from "https://cdn.jsdelivr.net/npm/@nylas/web-elements@latest/dist/cdn/nylas-scheduling/nylas-scheduling.es.js";
      
      defineCustomElement();  
      
      const nylasScheduling = document.querySelector('nylas-scheduling');

      // Set the scheduler configuration ID if using public configuration (`requires_session_auth=false`)
      nylasScheduling.configurationId = '<SCHEDULER_CONFIG_ID>';
      
      // OR, Set the scheduler session ID if using private configuration (`requires_session_auth=true`)
      // nylasScheduling.sessionId = '<SCHEDULER_SESSION_ID>';
    </script>
  </body>
</html>   
import React from 'react';
import { NylasScheduling } from '@nylas/react';

function App() {
  // Set the scheduler configuration ID if using public configuration (`requires_session_auth=false`)
  const configId = '<SCHEDULER_CONFIG_ID>';
  return <NylasScheduling configurationId={configId} />;

  // OR, Set the scheduler session ID if using private configuration (`requires_session_auth=true`)
  // const sessionId = '<SCHEDULER_SESSION_ID>';
  // return <NylasScheduling sessionId={sessionId} />;
}

export default App;

For more information, see the Scheduler UI Components reference documentation.

Create a configuration

Next, create a configuration for your first event. A configuration defines your preferred event settings and preferences. Nylas Scheduler stores Configuration objects in the Scheduler database, and loads them as Scheduling Pages in the Scheduler UI.

You can create a configuration either using the Scheduler API or using the Scheduler Editor.

Create a configuration using the Scheduler API

You can make a POST /v3/grants/<NYLAS_GRANT_ID>/scheduling/configurations request to create a configuration.

By default, Nylas creates a public configuration that doesn't require a session. See Scheduler configurations for more information.

The response includes the ID of the Configuration object.

curl --request POST \
  --url "https://api.us.nylas.com/v3/grants/<NYLAS_GRANT_ID>/scheduling/configurations" \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <NYLAS_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
    "requires_session_auth": false,
    "participants": [
      {
        "name": "Test",
        "email": "nylas_test_8",
        "is_organizer": true,
        "availability": {
          "calendar_ids": [
            "primary"
          ]
        },
        "booking": {
          "calendar_id": "primary"
        }
      }
    ],
    "availability": {
      "duration_minutes": 30
    },
    "event_booking": {
      "title": "My test event"
    }
  }'   
{
  "ID": "AAAA-BBBB-1111-2222",
  "participants": [
    {
      "name": "Nylas",
      "email": "nylas@example.com",
      "is_organizer": true,
      "availability": {
        "calendar_ids": [
          "primary"
      ]},
      "booking": {
        "calendar_id": "primary"
  }}],
  "availability": {
    "duration_minutes": 30
  },
  "event_booking": {
    "title": "My test event"
  }
}

Create a configuration using the Scheduler Editor

When you create a Scheduling Page using the Scheduler Editor in the UI, Nylas creates a corresponding configuration.

⚠️ You must have a working front-end UI to use the Scheduler Editor to create a configuration. Follow the Scheduler Quickstart guide to get a local development environment up and running.

To create a configuration using the Scheduler Editor, follow these steps:

  1. To use the Scheduler UI Components, include the Scheduler Editor and Scheduling scripts in your app.

    • Set nylasSessionsConfig. The Scheduler Editor Component uses the Hosted authentication details in nylasSessionsConfig to interact with the Nylas APIs. For more information on the required properties and other authentication options, see Set up the Scheduler Editor Component.
    • By default, Nylas creates a public configuration that doesn't require a session (requires_session_auth: false). For more information, see Scheduler configurations.

    The following examples add the Nylas Scheduler Editor and Scheduling scripts, and create a public configuration. The React example includes both Scheduler Editor and the Scheduling Page scripts in one file.

  1. In the UI, create a Scheduling Page from the Scheduler Editor. Creating a Scheduling Page creates a corresponding configuration.

(Optional) Create a session

💡 If you created a public configuration in the previous step, you can skip to the next step.

Next, create a session by making a POST /v3/scheduling/sessions request. When you create a session, you must include the Configuration object ID that you generated in the previous step. Nylas recommends you set a Time-to-Live (TTL) value for each session, and refresh the sessions as they expire.

The response includes the ID of the session.

curl --request POST \
  --url "https://api.us.nylas.com/v3/scheduling/sessions" \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <NYLAS_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
    "configuration_id": "AAAA-BBBB-1111-2222",
    "time_to_live": 10
  }'   
{
  "request_id": "5fa64c92-e840-4357-86b9-2aa364d35b88",
  "data": {
    "session_id": "XXXX-YYYY-1111-2222"
  }
}

Set up the Scheduler UI Components

💡 If you created a configuration using the Scheduler Editor, you can skip to the next step.

Set up the Scheduler Editor Component

To modify the configuration in the UI, you can set up the Scheduler Editor component.

Set the nylasSessionsConfig property. The Scheduler Editor Component uses the Hosted authentication details in nylasSessionsConfig to interact with the Nylas APIs.

Property Description
clientId The client ID from the Nylas Dashboard.
redirectUri The URL that the OAuth provider sends end users back to after they authenticate.
domain The Nylas authentication domain. For the U.S. data center, use https://api.us.nylas.com/v3. For the E.U. data center, use https://api.eu.nylas.com/v3.
hosted Whether to redirect end users to the hosted login component.
accessType Whether Nylas should return a refresh token along with the exchange token. 
<html>
  <body>
    <nylas-scheduler-editor />

    <script type="module">
      
      import { defineCustomElement } from "https://cdn.jsdelivr.net/npm/@nylas/web-elements@latest/dist/cdn/nylas-scheduler-editor/nylas-scheduler-editor.es.js";

      defineCustomElement();

      const schedulerEditor = document.querySelector("nylas-scheduler-editor");
      schedulerEditor.nylasSessionsConfig = {
        clientId: 'NYLAS_CLIENT_ID', // Replace with your Nylas client ID
        redirectUri: `${window.location.origin}/scheduler-editor`,
        domain: 'https://api.us.nylas.com/v3', // or 'https://api.eu.nylas.com/v3' for EU data center
        hosted: true,
        accessType: 'offline',
      }
    </script>
  </body>
</html>   
import React from 'react';
import { NylasSchedulerEditor } from "@nylas/react";

function App() {
  return (
    <NylasSchedulerEditor
      nylasSessionsConfig={{
        clientId: "NYLAS_CLIENT_ID", // Replace with your Nylas client ID
        redirectUri: `${window.location.origin}/scheduler-editor`,
        domain: "https://api.us.nylas.com/v3", // or 'https://api.eu.nylas.com/v3' for EU data center
        hosted: true,
        accessType: 'offline'
      }}
    />
  );
}
export default App;

✨ If you're already using Nylas Hosted authentication in your application, or you want to use Custom auth, you can use nylasApiRequest to update the authentication settings in Scheduler.

Set up the Scheduling Component

The Scheduling Component requires either a sessionId (private configuration) or a configurationId (public configuration) to load the Scheduling Page with the associated configuration.

By default, the Scheduling Component renders all of its sub-components (mode="app"). If nothing is configured in the app mode, Scheduler follows the standard booking flow. See Using the Scheduling Component for more information about configuration modes.

<html>
  <body>
    <nylas-scheduling
      configurationId="<SCHEDULER_CONFIG_ID>" /> 
      <!-- OR set the scheduler session ID if using private configuration (`requires_session_auth=true`)-->
      <!-- sessionId="<SCHEDULER_SESSION_ID>"--> 
    <script type="module">

      import { defineCustomElement } from "https://cdn.jsdelivr.net/npm/@nylas/web-elements@latest/dist/cdnnylas-scheduling/nylas-scheduling.es.js";
          
      defineCustomElement();
      ...
    </script>
  </body>
</html>   
import React from 'react';
import { NylasSchedulerEditor } from "@nylas/react";

function App() {
  return (
    <NylasScheduling
      // Set the scheduler configuration ID if using public configuration (`requires_session_auth=false`)
      configurationId={"<SCHEDULER_CONFIG_ID>"}
      // OR set the scheduler session ID if using private configuration (`requires_session_auth=true`)
      // sessionId={"<SCHEDULER_SESSION_ID>"} 
    />
  );
}
export default App;

Set up rescheduling and cancelling options

Booking confirmations and email notifications can include buttons that allow the participant to reschedule or cancel the booking. If they click one of the buttons, they're redirected to the corresponding page where they can make changes to their booking.

To set up the rescheduling and cancelling options, you need to create the rescheduling and cancellation pages, then add the URLs to the configuration.

Create rescheduling and cancellation pages

Before you can include the option to reschedule or cancel a booking, you must create corresponding pages and set up their URLs.

To create a page to reschedule an existing booking, add the rescheduleBookingRef property to the Scheduling Component and set it to the booking reference that you want to update.

To create a page to cancel an existing booking, include the cancelBookingRef property to the Scheduling Component and set it to the booking reference that you want to cancel.

🔍 You can find the booking reference in the URL of the email notification. For example, https://example.com/mail/#inbox/FMfcgzGxSlVHnZBcBwnfPWvtvjZjpqbZ.

<NylasScheduling
  rescheduleBookingRef="<BOOKING_REFERENCE>"
  // You also need to set the scheduler session ID if using private configuration (`requires_session_auth=true`)
  // sessionId={"<SCHEDULER_SESSION_ID>"} 
/>   
<NylasScheduling
  cancelBookingRef="<BOOKING_REFERENCE>"
  // You also need to set the scheduler session ID if using private configuration (`requires_session_auth=true`)
  // sessionId={"<SCHEDULER_SESSION_ID>"} 
/>

Add URLs to the configuration

You can add the URLs to the configuration either using the Scheduler API or modifying the Scheduler Editor Component.

Add URLs to configuration using the Scheduler API

To update the configuration, make a PUT /v3/grants/<NYLAS_GRANT_ID>/scheduling/configurations/<SCHEDULER_CONFIG_ID> request with scheduler.rescheduling_url and scheduler.cancelling_url.

curl --request PUT \
  --url "https://api.us.nylas.com/v3/grants/<NYLAS_GRANT_ID>/scheduling/configurations/<SCHEDULER_CONFIG_ID>" \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <NYLAS_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
    "scheduler": {
      "rescheduling_url": "https://www.example.com/reschdule/:booking_ref",
      "cancellation_url": "https://www.example.com/cancel/:booking_ref" 
    }
  }'   
{
  "ID": "AAAA-BBBB-1111-2222",
  "participants": [
    {
      "name": "Nylas",
      "email": "nylas@example.com",
      "is_organizer": true,
      "availability": {
        "calendar_ids": [
          "primary"
      ]},
      "booking": {
        "calendar_id": "primary"
  }}],
  "availability": {
    "duration_minutes": 30
  },
  "event_booking": {
    "title": "My test event"
  },
  "scheduler": {
    "rescheduling_url": "https://www.example.com/reschduling/:booking_ref",
    "cancellation_url": "https://www.example.com/cancelling/:booking_ref"
  }
}

Modify the Scheduler Editor Component

To update the configuration in the Scheduler Editor Component, set the rescheduling_url and cancelling_url parameters. These should correspond with the URLs of the rescheduling and cancelling pages you created.

<html>
  <body>
    <nylas-scheduler-editor />
      
    <!-- Configure the Nylas Scheduler Editor Component -->
    <script type="module">
      
      import { defineCustomElement } from "https://cdn.jsdelivr.net/npm/@nylas/web-elements@latest/dist/cdn/nylas-scheduler-editor/nylas-scheduler-editor.es.js";
      
      defineCustomElement();

      const schedulerEditor = document.querySelector('nylas-scheduler-editor');
      schedulerEditor.nylasSessionsConfig = {
        clientId: 'NYLAS_CLIENT_ID', // Replace with your Nylas client ID
        redirectUri: `${window.location.origin}/scheduler-editor`,
        domain: 'https://api.us.nylas.com/v3', // or 'https://api.eu.nylas.com/v3' for EU data center
        hosted: true,
        accessType: 'offline',
      }
      schedulerEditor.defaultSchedulerConfigState = {
        selectedConfiguration: {
          scheduler: { // The callback URLs to be set in email notifications
            rescheduling_url: `${window.location.origin}/reschedule/:booking_ref`, // The URL of the email notification includes the booking reference
            cancellation_url: `${window.location.origin}/cancel/:booking_ref`
          },
        },
      };
    </script>
  </body>
</html>   
import React from 'react';
import { NylasSchedulerEditor } from "@nylas/react";

function App() {
  return (
    <NylasSchedulerEditor               
      nylasSessionsConfig={{
        clientId: "<NYLAS_CLIENT_ID>", // Replace with your Nylas client ID
        redirectUri: `${window.location.origin}/scheduler-editor`,
        domain: "https://api.us.nylas.com/v3", // or 'https://api.eu.nylas.com/v3' for EU data center
        hosted: true,
        accessType: 'offline',
      }}
      defaultSchedulerConfigState={{
        selectedConfiguration: {
          scheduler: { // The callback URLs to be set in email notifications
            rescheduling_url:`${window.location.origin}/reschedule/:booking_ref`, // The URL of the email notification includes the booking reference
            cancellation_url:`${window.location.origin}/cancel/:booking_ref`
          }
        }
      }}
    />
  );
}
export default App;

(Optional) Change your Scheduling Page name

By default, Scheduling Pages use the organizer's user name as the Page name, which Nylas displays in the top-left corner of the calendar view. You can change the Page name on the Event info tab.

(Optional) Style components using CSS shadow parts

The Scheduler UI Components support CSS shadow parts (::part()) for a higher level of UI customization. CSS shadow parts allow you to style certain parts of a web component without having to modify its internal structure or styles directly. For more information on available shadow parts, see the Scheduler UI Components reference documentation.

The following CSS sets the background and foreground colors for a component on the Scheduling Page.

/* Your stylesheet */
