​
Use QStash via:

Below are some examples to get you started. You can also check the how to section for more technical details or the API reference to test the API.

​
Publish a message to an endpoint

Simple example to publish a message to an endpoint. 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://example.com'

​
Publish a message to a topic

The topic is a way to publish a message to multiple endpoints in a fan out pattern. 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/myTopic'

​
Publish a message with 5 minutes delay

Add a delay to the message to be published. After QStash receives the message, it will wait for the specified time (5 minutes in this example) before sending the message to the endpoint. 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -H "Upstash-Delay: 5m" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://example.com'

​
Send a custom header

Add a custom header to the message to be published. 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H 'Upstash-Forward-My-Header: my-value' \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://example.com'

​
Schedule to run once a day

curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Upstash-Cron: 0 0 * * *" \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/schedules/https://example.com'

​
Set max retry count to 3

Configure how many times QStash should retry to send the message to the endpoint before sending it to the dead letter queue. 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Upstash-Retries: 3" \
    -H "Content-type: application/json" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://example.com'

​
Set callback url

Receive a response from the endpoint and send it to the specified callback URL. If the endpoint returns a response, QStash will send it to the failure callback URL. 
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -H "Upstash-Callback: https://example.com/callback" \
    -H "Upstash-Failure-Callback: https://example.com/failure" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/publish/https://example.com'
