2018-12-30 18:01:46 UTC - Facundo Rodriguez: If I want to build a consumer via websocket I have to produce via websocket? Because I build a producer using Pulsa client when I a consumer user the Pulsar client works perfectly but when I want to consume from a ReactJS componen via websocket the handshake returns 400 instead of 101

no. you don’t need to produce via websocket.

make sure you are using the right topic name

2018-12-31 00:37:20 UTC - Facundo Rodriguez: this is mi producer `producer = client.create_producer('<persistent://public/default/orderbook/pair>')`
and this is my consumer
```
TOPIC = '<ws://localhost:8080/ws/v2/consumer/persistent/public/default/orderbook/pair/suscription-1>'

async def orderbook_consumer():
    async with websockets.connect(TOPIC) as websocket:
        data = await websocket.recv()
        print(f"&lt; {data}")
```

can you try ‘<persistent://public/default/orderbook_pair>’ (let try not use ‘/’ in the topic name)
