QStash

aid: qstash
name: 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.

  description: 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.
