**Note**  
AWS Chatbot is now Amazon Q Developer. [Learn more](https://docs.aws.amazon.com/chatbot/latest/adminguide/service-rename.html)   
Mentions of the name AWS Chatbot still appear in this guide.

The *Amazon Q Developer in chat applications API Reference* provides descriptions, API request parameters, and the XML response for each of the Amazon Q Developer API actions.

APIs are currently available in the following Regions:
+ US East (Ohio) - `us-east-2` 
+ US West (Oregon) - `us-west-2` 
+ Asia Pacific (Singapore) - `ap-southeast-1` 
+ Europe (Ireland) - `eu-west-1` 

The Amazon Q Developer in chat applications console can only be used in US East (Ohio). Your configuration data however, is stored in each of the relevant available Regions.

**Note**  
Your AWS CloudTrail events are logged in whatever Region you call from, not US East (N. Virginia) by default.
