Examples
Publish
You can run the async code by importing AsyncQStash
from qstash
and awaiting the methods.
Publish to a URL with a 3 second delay and headers/body
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
res = client.message.publish_json(
url="https://my-api...",
body={
"hello": "world",
},
headers={
"test-header": "test-value",
},
delay="3s",
)
print(res.message_id)
Publish to a URL group with a 3 second delay and headers/body
You can make a URL group on the QStash console or using the URL group API
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
res = client.message.publish_json(
url_group="my-url-group",
body={
"hello": "world",
},
headers={
"test-header": "test-value",
},
delay="3s",
)
# When publishing to a URL group, the response is an array of messages for each URL in the group
print(res[0].message_id)
Publish a method with a callback URL
Callbacks are useful for long running functions. Here, QStash will return the response of the publish request to the callback URL.
We also change the method
to GET
in this use case so QStash will make a GET
request to the url
. The default
is POST
.
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
client.message.publish_json(
url="https://my-api...",
body={
"hello": "world",
},
callback="https://my-callback...",
failure_callback="https://my-failure-callback...",
method="GET",
)
Configure the number of retries
The max number of retries is based on your QStash plan
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
client.message.publish_json(
url="https://my-api...",
body={
"hello": "world",
},
retries=1,
)
Publish HTML content instead of JSON
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
client.message.publish(
url="https://my-api...",
body="<html><body><h1>Hello World</h1></body></html>",
content_type="text/html",
)
Publish a message with content-based-deduplication
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
client.message.publish_json(
url="https://my-api...",
body={
"hello": "world",
},
content_based_deduplication=True,
)
Publish a message with timeout
Timeout value to use when calling a url (See Upstash-Timeout
in Publish Message page)
from qstash import QStash
client = QStash("<QSTASH-TOKEN>")
client.message.publish_json(
url="https://my-api...",
body={
"hello": "world",
},
timeout="30s",
)
