Quotas and Limits

This document contains current API restrictions and usage limits on use of Dialogflow. This page will be updated to reflect any changes to these restrictions and usage limits. We reserve the right to change these limits.

Quotas differ based on the Dialogflow edition and pricing plan. To find out more about the different Dialogflow editions, see Dialogflow Editions.

These quotas apply to each Dialogflow GCP project and are shared across all applications and IP addresses using a given GCP project. To request a higher quota for a Dialogflow Enterprise Edition agent, click an edit button for a quota on the Quotas tab of the Google Cloud Platform Dashboard, and then click Apply for a higher quota in the quota edit form to submit a Dialogflow Quota Increase Request.
