Quotas, limits, and configuration values for Power Virtual Agents

This topic contains quotas, limits, and configuration values for Power Virtual Agents.


Quotas are default constraints applied to chatbots that limit how often messages can be sent to the chatbot. The purpose of quotas is to throttle the client's service load, which protects a service from being overloaded and the client from unexpected resource usage.

Quotas are applied to your chatbots alongside the capacity constraints you gained by purchasing a Power Virtual Agents plan. Also see Licensing and capacity considerations.

The following quotas, defined as requests per minute (RPM), apply to Power Virtual Agents chatbots.

Action Quota with the paid plan
Messages to a chatbot
(Includes any message from a user or integrations, such as Azure Bot Framework Skills, to a single chatbot.)
800 RPM per bot

If the quota for messages to a chatbot is met, the user chatting with the chatbot will see a failure notice when they try to send a message. They'll be prompted to retry.

Error message in the chat bot window that says 'Send failed. Retry.'.


These limits apply to the Power Virtual Agents web app and the Power Virtual Agents app in Microsoft Teams.
