Google Dialogflow Rate Limits

Published Dialogflow quotas and limits, read from Google's own quotas page on 2026-09-12. This file replaces a 2026-05-04 scaffold whose numbers (10 rpm free / 100 rpm pro / 1000 rpm enterprise, X-RateLimit-* headers) were placeholder defaults and matched nothing Google publishes. Quotas apply per Google Cloud project and are shared across every application and IP using that project. Paid editions can request an increase; fixed limits cannot be raised.

Google Dialogflow Rate Limits is the machine-readable rate-limit profile for Google Dialogflow on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 25 rate-limit definitions, across the Dialogflow CX Edition, Dialogflow ES Trial Edition, Dialogflow ES Essentials Edition, Dialogflow ES (both editions), and Agent Assist (Essentials Edition) tiers, measuring requests_per_minute, tokens_per_minute, phone_minutes_per_minute, requests_per_day, and requests_per_month.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, canonicalStatus, and detailsType.

Tagged areas include Conversational AI, Quotas, and Rate Limiting.

Policies

Back-off
Stated in the SLA itself, not just in guidance: after the first error wait a minimum of 1 second, then increase the interval exponentially up to 32 seconds. Meeting this is a customer obligation for SLA credit eligibility.
Quota increase
Paid editions can request an increase through the Cloud console quotas page. ES agents must be upgraded to the Essentials edition first. If the authenticating project differs from the project holding the agent, the increase must be requested on the consumer project.
Session retention
A session remains active and its data is stored for 30 minutes after the last request.
