Receiver

✓ from qstash import Receiver

Initialize client with your QStash token (from Upstash console) and publish a message.

import os from qstash import QStashClient client = QStashClient(token=os.environ.get('QSTASH_TOKEN', '')) response = client.publish(url="https://example.com/api", body="Hello, QStash!") print(response)

Debug

Known issues

breakingIn v3.0.0, the entire LLM chat completion support was removed. Any code using `client.llm.chat` or similar will break.

fix

Migrate to a separate LLM SDK (e.g., OpenAI) and remove usage of deprecated methods.

affects: <3.0.0

deprecatedThe `delay` and `not_before` parameters in `enqueue` are removed in v2.0.1+. Use `schedule` or manual delay instead.

fix

Remove these parameters; if you need delayed execution, use schedules or set a later `not_before` via the API's `schedule` method.

affects: <2.0.1

gotchaClient initialization can fail silently if the token is missing; always validate `QSTASH_TOKEN` is set.

fix

Check that the environment variable exists before creating the client: `assert os.environ.get('QSTASH_TOKEN'), 'Missing QStash token'`

affects: all

gotchaAsync client requires an event loop; using it in synchronous context will raise RuntimeError.

fix

Ensure you use `await` inside an async function or run with `asyncio.run()`. Example: `asyncio.run(main())`.

affects: all
