The following videos explain concepts that help you learn various Gmail
developer features such as the REST API, email markup, and
Add-ons for your applications. Each video generally walks you
through a short sample app to help you quickly get started with a specific
feature.
Introducing the Gmail API
Why did Google create the Gmail API? This video gives developers a
history of programmatic access to email and the motivation that led to why an
API for Gmail was created. With the Gmail API, go
beyond what standard email protocols allow developers to do!
(Running time: 5:42)
Revolutionizing email access with the Gmail API
After a review of the Gmail API, this video digs into an intermediate
example that displays the Subject line for chatty email threads (those with
three or more messages). Viewers not only get a walkthough of the code but also
get a bonus US history lesson!
(Running time: 8:32)
Modifying your signature with the Gmail API
The Gmail API lets developers create apps that modify user settings.
This video walks you through an example of modifying user
signatures.
Other settings the API can modify include email forwarding, vacation responder,
external access via IMAP/POP, and filters.
Developers can use markup to add actions to emails, increasing user engagement.
This video shows how you can enhance your customers’ experience by simply adding
email markup to the
messages you're already sending them.

Expediting expense reports with Gmail Add-ons
Add-ons let you extend Gmail as well as integrate
functionality from your app into Gmail's user interface. In
this video, learn about the ExpenseIt! Gmail
Add-on
— an app that helps working professionals process receipts directly from
their inbox into a spreadsheet, creating a single place to complete their
expense reports. Build the add-on piece-by-piece with
its corresponding codelab.
