How addons work

Enable an addon and new steps appear in your flow editor. Configure them with your API keys and common requests are preconfigured, so you spend less time wiring provider APIs by hand.

For example, enabling the Stripe addon gives you steps like "Create Payment Intent" and "Create Customer." Enabling OpenAI gives you AI steps for text and image workflows. Each step handles authentication, request formatting, and error handling for you.
