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. type: Index image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg url: https://raw.githubusercontent.com/api-evangelist/qstash/refs/heads/main/apis.yml created: '2026-06-12' modified: '2026-06-12' specificationVersion: '0.19' tags: - Message Queue - Task Scheduling - Serverless - HTTP Messaging - Background Jobs - Webhooks - Dead Letter Queue - CRON - Upstash apis: - aid: qstash:qstash-api name: QStash API 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.
