# IBKR TWS API

The TWS API content has been massively updated:

* Request, receive, and cancellation methods for the same behavior are now condensed to the same page.
* Guides have been updated to better indicate modern installation platforms
* Many URL paths have been shortened and clarified.
* "Introduction" sections have been renamed for clearer distinction. These were largely combined with limitations pages for clearer consolidation.
* [Error Codes](/docs/tws-api/doc/error/codes) 2113 through 2189 have been added with descriptions of the error code.

There is a known issue with the llms.txt file not mapping correctly, that will be resolved in the near future.
