🐢 Webex API Rate Limiting
A popular blog post by Technical Solutions Specialist, Taylor Hanson, has been updated for 2025. This article covers how the Webex API has rate limits in place for different resources, such as /messages and /rooms, to protect from distributed denial of service attacks. These limits will vary depending on the calls being made, how resource intensive that call is on the servers, and how many servers are actively in routing – and is subject to change as needed to protect all use cases from failing in the event of a large batch of requests. Check out the blog to learn how to handle these API rate limits in your app and keep things running smoothly.
