Airtable’s API allows you to issue create, read, update and delete operations into any base you have access to. It also dynamically modifies itself to match a given base’s schema. As you add and modify fields and tables, the API will automatically adjust to reflect those changes. The Airtable API removes the boilerplate, grunt work of building a CRUD interface to your database allowing you to rapidly prototype your applications and focus on aspects of your application that are more impactful for your given use-case.
To load the documentation for your specific base, go to https://airtable.com/api and select the base you want to use. The documentation will describe how to successfully complete CRUD operations into each table in your base.
