QStash requires a publicly available API to send messages to. If you want to develop locally, you need to run a tunnel. We are planning to offer a native solution, but for the moment please use a 3rd party tunnel.

​
ngrok

ngrok is a free service, that provides you with a public endpoint and forwards all traffic to your localhost.

​
Sign up

Create a new account on dashboard.ngrok.com/signup and follow the instructions to download the ngrok CLI and connect your account: 
ngrok config add-authtoken XXX

​
Start the tunnel

Choose the port where your application is running. Here I’m forwarding to port 3000, because Next.js is using it. 
$ ngrok http 3000

​
Publish a message

Now copy the Forwarding url and use it as destination in QStash. Make sure to add the path of your API at the end. (/api/webhooks in this case) 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://e02f-2a02-810d-af40-5284-b139-58cc-89df-b740.eu.ngrok.io/api/webhooks'

​
Debug

In case messages are not delivered or something else doesn’t work as expected, you can go to http://127.0.0.1:4040 to see what ngrok is doing.
