See Conversations Limits for a detailed list on length, media, and other limits.
GET actions are not accessible for the API endpoints.
Due to various limitations and concerns, Flex Conversations will constrain certain actions.
The Interactions API has a limit of 20 requests per second per endpoint per account. The API returns an HTTP 429 status when rate limits are exceeded and should be handled accordingly on the customer side.
The Flex Webchat orchestrator currently has a rate limit of 5 requests per second beyond which the customer can get throttled. When exceeded, the API returns an HTTP 429.
