subtitle: Configure individual function behavior. Customize authentication, dependencies, and other settings per function.

|
## Configuration
|
|
|
|
By default, all your Edge Functions have the same settings. In real applications, however, you might need different behaviors between functions.
|
|
|
|
For example:
|
|
|
|
- **Stripe webhooks** need to be publicly accessible (Stripe doesn't have your user tokens)
|
|
- **User profile APIs** should require authentication
|
|
- **Some functions** might need special dependencies or different file types
|
|
|
|
To enable these per-function rules, create `supabase/config.toml` in your project root:
|
|
|
|
```toml
|
|
# Disables authentication for the Stripe webhook.
|
|
[functions.stripe-webhook]
|
|
verify_jwt = false
|
|
|
|
# Custom dependencies for this specific function
|
|
[functions.image-processor]
|
|
import_map = './functions/image-processor/import_map.json'
|
|
|
|
# Custom entrypoint for legacy function using JavaScript
|
|
[functions.legacy-processor]
|
|
entrypoint = './functions/legacy-processor/index.js
|
|
```
|
|
|
|
This configuration tell Supabase that the `stripe-webhook` function doesn't require a valid JWT, the `image-processor` function uses a custom import map, and `legacy-processor` uses a custom entrypoint.
|
|
|
|
You set these rules once and never worry about them again. Deploy your functions knowing that the security and behavior is exactly what each endpoint needs.

## Skipping authorization checks
|
|
|
|
By default, Edge Functions require a valid JWT in the authorization header. If you want to use Edge Functions without Authorization checks (commonly used for Stripe webhooks), you can configure this in your `config.toml`:
|
|
|
|
```toml
|
|
[functions.stripe-webhook]
|
|
verify_jwt = false
|
|
```
|
|
|
|
You can also pass the `--no-verify-jwt` flag when serving your Edge Functions locally:
|
|
|
|
```bash
|
|
supabase functions serve hello-world --no-verify-jwt
|
|
```
|
|
|
|
<Admonition type="caution">
|
|
|
|
Be careful when using this flag, as it will allow anyone to invoke your Edge Function without a valid JWT. The Supabase client libraries automatically handle authorization.

## Custom entrypoints
|
|
|
|
<Admonition type="note">
|
|
|
|
`entrypoint` is available only in Supabase CLI version 1.215.0 or higher.
|
|
|
|
</Admonition>
|
|
|
|
When you create a new Edge Function, it will use TypeScript by default. However, it is possible to write and deploy Edge Functions using pure JavaScript.
|
|
|
|
Save your Function as a JavaScript file (e.g. `index.js`) update the `supabase/config.toml` :
|
|
|
|
```toml
|
|
[functions.hello-world]
|
|
entrypoint = './index.js' # path must be relative to config.toml
|
|
```
|
|
|
|
You can use any `.ts`, `.js`, `.tsx`, `.jsx` or `.mjs` file as the entrypoint for a Function.
