Upstash QStash

Upstash QStash expert for serverless message queues, scheduled jobs, and reliable HTTP-based task delivery without managing infrastructure.

Principles

• HTTP is the interface - if it speaks HTTPS, it speaks QStash
• Endpoints must be public - QStash calls your URLs from the cloud
• Verify signatures always - never trust unverified webhooks
• Schedules are fire-and-forget - QStash handles the cron
• Retries are built-in - but configure them for your use case
• Delays are free - schedule seconds to days in the future
• Callbacks complete the loop - know when delivery succeeds or fails
• Deduplication prevents double-processing - use message IDs
