Google today announced the general availability of a new API for Google Docs that will allow developers to automate many of the tasks that users typically do manually in the company’s online office suite. The API has been in developer preview since last April’s Google Cloud Next 2018 and is now available to all developers.

As Google notes, the REST API was designed to help developers build workflow automation services for their users, build content management services and create documents in bulk. Using the API, developers can also set up processes that manipulate documents after the fact to update them, and the API also features the ability to insert, delete, move, merge and format text, insert inline images and work with lists, among other things.

The canonical use case here is invoicing, where you need to regularly create similar documents with ever-changing order numbers and line items based on information from third-party systems (or maybe even just a Google Sheet). Google also notes that the API’s import/export abilities allow you to use Docs for internal content management systems.

Some of the companies that built solutions based on the new API during the preview period include Zapier, Netflix, Mailchimp and Final Draft. Zapier integrated the Docs API into its own workflow automation tool to help its users create offer letters based on a template, for example, while Netflix used it to build an internal tool that helps its engineers gather data and automate its documentation workflow.
