API Rate Limit Response - Upstash Documentation

Overview

There is no request per second limit for operational API's as listed below:

trigger, publish, enqueue, notify, wait, batch
Other endpoints (like logs,listing flow-controls, queues, schedules etc) have rps limit. This is a short-term limit per second to prevent rapid bursts of requests.

Headers:

Burst-RateLimit-Limit: Maximum number of requests allowed in the burst window (1 second)
Burst-RateLimit-Remaining: Remaining number of requests in the burst window (1 second)
Burst-RateLimit-Reset: Time (in unix timestamp) when the burst limit will reset

Example Rate Limit Error Handling

Handling Daily Rate Limit Error

import { QstashDailyRatelimitError } from "@upstash/qstash";try {  // Example of a publish request that could hit the daily rate limit  const result = await client.publishJSON({    url: "https://my-api...",    // or urlGroup: "the name or id of a url group"    body: {      hello: "world",    },  });} catch (error) {  if (error instanceof QstashDailyRatelimitError) {    console.log("Daily rate limit exceeded. Retry after:", error.reset);    // Implement retry logic or notify the user  } else {    console.error("An unexpected error occurred:", error);  }}

Handling Burst Rate Limit Error

import { QstashRatelimitError } from "@upstash/qstash";try {  // Example of a request that could hit the burst rate limit  const result = await client.publishJSON({    url: "https://my-api...",    // or urlGroup: "the name or id of a url group"    body: {      hello: "world",    },  });} catch (error) {  if (error instanceof QstashRatelimitError) {    console.log("Burst rate limit exceeded. Retry after:", error.reset);    // Implement exponential backoff or delay before retrying  } else {    console.error("An unexpected error occurred:", error);  }}
