QStash

aid: qstash

description: >-
  QStash is a serverless message queue and task scheduling REST API from Upstash
  that delivers HTTP messages to endpoints reliably without requiring any
  long-lived connections or infrastructure management. Built entirely on
  stateless HTTP requests, it is designed for serverless and edge runtimes where
  traditional message brokers are impractical. QStash supports automatic retries,
  CRON-based scheduling up to one year in advance, URL group broadcasting for
  fan-out delivery, FIFO queuing, dead-letter queues, and message deduplication.
  Developers simply POST a message with a destination URL and QStash handles
  guaranteed delivery with configurable retry logic and flow control.

      The QStash REST API provides HTTP-based endpoints for publishing messages
      to destination URLs, managing queues, scheduling tasks with CRON
      expressions, configuring URL groups for fan-out delivery, retrieving
      message logs, and managing dead-letter queues. Authentication uses Bearer
      tokens obtained from the Upstash console.
