The API Step on the Voiceflow canvas can be a designer's best friend, allowing them to integrate with an Airtable base and access specific fields in an existing database. This integration enables designers to retrieve data using GET requests and save data to a connected base using POST requests. By utilizing these API steps, conversation designers can unlock access to information outside of the canvas, adding capabilities such as pulling or saving information from an existing base, mapping information to any variable in their design, and easily updating and delivering content in real-time. This integration also enables the creation of a single source of truth for scaling experiences, making them more malleable and flexible. The use cases for this API step are endless, including personal trackers, consumer product catalogs, and small business budgets, where an integrated Airtable database can provide accurate and up-to-date information. By adding the API step in the design and prototype stages, conversation designers can improve developer hand-off and rethink experiences across any channel.
