Email remains at the heart of how companies operate. That's why earlier this year, we previewed Gmail Add-ons—a way to help businesses speed up workflows. Since then, we've seen partners build awesome applications, and beginning today, we're extending the Gmail add-on preview to include all developers. Now anyone can start building a Gmail add-on.
Gmail Add-ons let you integrate your app into Gmail and extend Gmail to handle quick actions.
They are built using native UI context cards that can include simple text dialogs, images, links, buttons and forms. The add-on appears when relevant, and the user is just a click away from your app's rich and integrated functionality.
Gmail Add-ons are easy to create. You only have to write code once for your add-on to work on both web and mobile, and you can choose from a rich palette of widgets to craft a custom UI. Create an add-on that contextually surfaces cards based on the content of a message. Check out this video to see how we created an add-on to collate email receipts and expedite expense reporting.
Per the video, you can see that there are three components to the app's core functionality. The first component is getContextualAddOn()—this is the entry point for all Gmail Add-ons where data is compiled to build the card and render it within the Gmail UI. Since the add-on is processing expense reports from email receipts in your inbox, the createExpensesCard() parses the relevant data from the message and presents them in a form so your users can confirm or update values before submitting. Finally, submitForm()takes the data and writes a new row in an "expenses" spreadsheet in Google Sheets, which you can edit and tweak, and submit for approval to your boss.
getContextualAddOn()
createExpensesCard()
submitForm()
Check out the documentation to get started with Gmail Add-ons, or if you want to see what it's like to build an add-on, go to the codelab to build ExpenseIt step-by-step. While you can't publish your add-on just yet, you can fill out this form to get notified when publishing is opened. We can't wait to see what Gmail Add-ons you build!
You might be using the Google Calendar API, or alternatively email markup, to insert events into your users' calendars. Thankfully, these tools allow your apps to do this seamlessly and automatically, which saves your users a lot of time. But what happens if plans change? You need your apps to also be able to modify an event.
While email markup does support this update, it's limited in what it can do, so in today's video, we'll show you how to modify events with the Calendar API. We'll also show you how to create repeating events. Check it out:
Imagine a potential customer being interested in your product, so you set up one or two meetings with them. As their interest grows, they request regularly-scheduled syncs as your product makes their short list—your CRM should be able to make these adjustments in your calendar without much work on your part. Similarly, a "dinner with friends" event can go from a "rain check" to a bi-monthly dining experience with friends you've grown closer to. Both of these events can be updated with a JSON request payload like what you see below to adjust the date and make it repeating:
JSON
var TIMEZONE = "America/Los_Angeles"; var EVENT = { "start": {"dateTime": "2017-07-01T19:00:00", "timeZone": TIMEZONE}, "end": {"dateTime": "2017-07-01T22:00:00", "timeZone": TIMEZONE}, "recurrence": ["RRULE:FREQ=MONTHLY;INTERVAL=2;UNTIL=20171231"] };
This event can then be updated with a single call to the Calendar API's events().patch() method, which in Python would look like the following given the request data above, GCAL as the API service endpoint, and a valid EVENT_ID to update:
events().patch()
GCAL
EVENT_ID
GCAL.events().patch(calendarId='primary', eventId=EVENT_ID, sendNotifications=True, body=EVENT).execute()
If you want to dive deeper into the code sample, check out this blog post. Also, if you missed it, check out this video that shows how you can insert events into Google Calendar as well as the official API documentation. Finally, if you have a Google Apps Script app, you can access Google Calendar programmatically with its Calendar service.
We hope you can use this information to enhance your apps to give your users an even better and timely experience.

At Google I/O 2016, we launched a new Google Sheets API—click here to watch the entire announcement. The updated API includes many new features that weren’t available in previous versions, including access to functionality found in the Sheets desktop and mobile user interfaces. My latest DevByte video shows developers how to get data into and out of a Google Sheet programmatically, walking through a simple script that reads rows out of a relational database and transferring the data to a brand new Google Sheet.
Let’s take a sneak peek of the code covered in the video. Assuming that SHEETS has been established as the API service endpoint, SHEET_ID is the ID of the Sheet to write to, and data is an array with all the database rows, this is the only call developers need to make to write that raw data into the Sheet:
SHEETS
SHEET_ID
data
SHEETS.spreadsheets().values().update(spreadsheetId=SHEET_ID, range='A1', body=data, valueInputOption='RAW').execute()
rows = SHEETS.spreadsheets().values().get(spreadsheetId=SHEET_ID, range='Sheet1').execute().get('values', []) for row in rows: print(row)
If you’re ready to get started, take a look at the Python or other quickstarts in a variety of languages before checking out the DevByte. If you want a deeper dive into the code covered in the video, check out the post at my Python blog. Once you get going with the API, one of the challenges developers face is in constructing the JSON payload to send in API calls—the common operations samples can really help you with this. Finally, if you’re ready to get going with a meatier example, check out our JavaScript codelab where you’ll write a sample Node.js app that manages customer orders for a toy company, the database of which is used in this DevByte, preparing you for the codelab.
We hope all these resources help developers create amazing applications and awesome tools with the new Google Sheets API! Please subscribe to our channel, give us your feedback below, and tell us what topics you would like to see in future episodes!
