Mail merge with the Google Docs API

Google Cloud's Developer Advocate, Wesley Chun, highlights the use of mail merge with the Google Docs API, emphasizing its utility for automatically generating various document types such as form letters and invoices for businesses and educational institutions. Mail merge involves combining a master template with a data source to create customized documents for different records, which can be distributed via mail or electronically. While Google Apps Script previously allowed script and add-on creation within its ecosystem, the introduction of the Google Docs API has simplified the development of custom mail merge applications by providing programmatic access through an HTTP-based REST API. This advancement enables developers to efficiently create and manage mail merge operations using various Google APIs like Docs, Sheets, Drive, and Gmail, with resources such as a technical overview video, a fully-working Python sample application, and open-source repositories available to facilitate the process.
