This is because it is expected that **your users** would define the actual **URL path** where they want to receive the webhook request in some other way (e.g. a web dashboard).

### Check the docs { #check-the-docs }

Now you can start your app and go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

    private void performHealthCheck() {
        log.debug("Performing multi-channel health check");

        for (ChannelGroup channelGroup : sessionChannels.values()) {
            for (ChannelInfo channel : channelGroup.getChannels()) {
                try {
                    // Simplified health check - in real implementation would ping the channel
                    boolean isHealthy = checkChannelHealth(channel);

The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

## Check it { #check-it }

Run the server and go to the docs: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You'll see the user interface like:

        req.txn_buf = getBuffer();
        rsp.txn_buf = getBuffer();
    }

    /**
     * Returns a buffer to the cache for reuse.
     *
     * Performance: O(1) operation with size limit check
     *
     * @param buf the buffer to return to the cache
     */
    static public void releaseBuffer(final byte[] buf) {
        // Validate buffer before returning to cache

위의 예시에서, `item_id`는 `int`로 선언되었습니다.

이 기능은 함수 내에서 오류 검사, 자동완성 등의 편집기 기능을 활용할 수 있게 해줍니다.

/// check | 확인

Puedes declarar el tipo de un parámetro de path en la función, usando anotaciones de tipos estándar de Python:

{* ../../docs_src/path_params/tutorial002.py hl[7] *}

En este caso, `item_id` se declara como un `int`.

/// check | Revisa

Esto te dará soporte del editor dentro de tu función, con chequeo de errores, autocompletado, etc.

## Check the Virtual Environment is Active { #check-the-virtual-environment-is-active }

Check that the virtual environment is active (the previous command worked).

This is **optional**, but it's a good way to **check** that everything is working as expected and you are using the virtual environment you intended.
