The ActionScript® 2 API described here has been deprecated. Yahoo! is proud to now offer an all-new ActionScript 3.0 API to developers. You can find the documentation, component download and examples on the Maps Section of the Flash Developer Center, here on the Yahoo! Developer Network.
We will continue to keep the ActionScript 2 documentation available right here for developers still using it, however Yahoo! will not continue to provide support for it and are recommending that everyone upgrade to the AS3 API to take advantage of the many new features.
The Yahoo! Flash Maps APIs are limited to 50,000 queries per IP per day. See information on rate limiting. For guidance on how to integrate these APIs into your business applications or to request a rate limit exception, please see our Usage Policy.
All Yahoo! Maps Web Services are discussed on the yws-maps mailing list.
The yws-maps-flash mailing list is available for Flash API specific questions.
