# Adding an endpoint to ExtendSchema
|
|
|
|
This document is intended for contrubtors to WooCommerce Blocks plugin, if you feel like a new endpoint should be added, feel free to open an issue or a PR detailing why.
|
|
|
|
## Extending `GET` endpoints in Store API.
|
|
|
|
ExtendSchema needs to expose each endpoint individually. If you want to expose a new endpoint, you have to follow these steps:
|
|
|
|
1. In `ExtendSchema` class, add your endpoint `IDENTIFIER` to the `$endpoints` variable.
|
|
|
|
```php
|
|
|
|
use Automattic\WooCommerce\Blocks\StoreApi\Schemas\BillingAddressSchema;
|
|
|
|
private $endpoints = [ /* other identifiers */, BillingAddressSchema::IDENTIFIER ];
|
|
|
|
```
|
|
|
|
This is to prevent accidentally exposing new endpoints.
|
|
|
|
2. Inside your endpoint schema class (for this example, inside `BillingAddressSchema`), in its `get_properties` method, add this call at the end of the returned array.
|
|
|
|
You can pass extra parameters to `get_extended_schema` and those would be passed to third party code.
|
|
|
|
```php
|
|
self::EXTENDING_KEY => $this->get_extended_schema( self::IDENTIFIER ),
|
|
```
|
|
|
|
`EXTENDING_KEY` value is `extensions`, we use a constant to make sure we don't have a typo.
|
|
|
|
3. Inside the same class, in `get_item_response`, add the below line. Like `get_extended_schema`, you can pass extra parameters here as well.
|
|
|
|
Make sure to only expose what's needed.
|
|
|
|
```php
|
|
self::EXTENDING_KEY => $this->get_extended_data( self::IDENTIFIER, $cart_item ),
|
|
```
|
|
|
|
That's it, your endpoint would now contain `extensions` in your endpoint, and you can consume it in the frontend.
|
|
|
|
Extending a new endpoint is usually half the work, you will need to receive this data in the frontend and pass it to any other extensibility point (Slot, Filter, Event).
