REST API

Creating API Routes

API routes are automatically created when you create Postgres Tables, Views, or Functions.

Create a table#

Create your first API route by creating a table called todos to store tasks. This creates a corresponding route todos which can accept GET, POST, PATCH, & DELETE requests.

  1. Go to the Table editor page in the Dashboard.
  2. Click New Table and create a table with the name todos.
  3. Click Save.
  4. Click New Column and create a column with the name task and type text.
  5. Click Save.
  6. In the Integrations > Data API section of the Dashboard, expose specific tables like todos or the functions you want to access. To automatically grant access for new tables and functions in public, enable Default privileges for new entities.

API URL and keys#

Every Supabase project has a unique API URL. Your API is secured behind an API gateway which requires an API Key for every request.

To do this, you need to get the Project URL and key from the project's Connect dialog.

See API keys for a full explanation of all key types and their uses.

The REST API is accessible through the URL https://<project_ref>.supabase.co/rest/v1

Both of these routes require the key to be passed through an apikey header.

Using the API#

You can interact with your API directly via HTTP requests, or you can use the client libraries which we provide.

See how to make a request to the todos table which we created in the first step, using the API URL (SUPABASE_URL) and Key (SUPABASE_PUBLISHABLE_KEY) we provided:

// Initialize the JS client
import { createClient } from '@supabase/supabase-js'
const supabase = createClient(SUPABASE_URL, SUPABASE_PUBLISHABLE_KEY)
// Make a request
const { data: todos, error } = await supabase.from('todos').select('*')

JS Reference: select(), insert(), update(), upsert(), delete(), rpc() (call Postgres functions).
