Technical Documentation Overview
Data API
Bubble's Data API allows external services to perform CRUD operations on your app's database over REST. Enable it under Settings → API and expose specific data types. Authenticate using an API token passed as a header:
Authorization: Bearer <your_api_token>
GET https://<your-app>.bubbleapps.io/api/1.1/obj/<data_type>
Workflow API
Trigger server-side Bubble workflows externally by exposing API Workflow endpoints. Define the workflow in the editor, mark it as "exposed as a public API endpoint", and call it via POST:
POST https://<your-app>.bubbleapps.io/api/1.1/wf/<workflow_name>
Content-Type: application/json
{ "param1": "value1" }
Plugin Development
Bubble's Plugin Editor lets developers build reusable elements and actions in JavaScript. Plugins can expose UI components, server-side actions (Node.js-like environment), and API connections for use by any Bubble app.
Key Concepts for Developers
- Data Types & Fields: Schema-based, with support for text, number, date, file, geographic address, and relational (linked) types.
- Privacy Rules: Row-level security rules on data types, evaluated server-side.
- Server-Side Workflows (Backend Workflows): Run logic server-side on a schedule or via API trigger — useful for webhooks, cron jobs, and data processing.
- Deployment & Versioning: Apps have a Development and Live version, with a one-click deploy mechanism. Custom domains supported on paid plans.
