With the\n[pending shutdown of `ClientLogin`](https://googledevelopers.blogspot.com/2015/02/reminder-clientlogin-shutdown-scheduled.html),\nwe're going to turn down the\n[old Webmaster Tools API](/search/blog/2008/06/get-cooking-with-webmaster-tools-api) on\nApril 20, 2015.\n\n\nIf you're still using the old API, getting started with the new one is fairly easy. The new API\ncovers everything from the old version except for messages and keywords. We have examples in\n[Python](/webmaster-tools/v3/quickstart/quickstart-python),\n[Java](/webmaster-tools/v3/quickstart/quickstart-java), as well as\n[OACurl](/webmaster-tools/v3/quickstart/quickstart-oacurl)\n(for command-line fans and quick testing). Additionally, there's the\n[Site Verification API](/site-verification)\nto add sites programmatically to your account. The\n[Python search query data download](/search/blog/2011/12/download-search-queries-data-using)\nwill continue to be available for the moment, and replaced by an API in the upcoming quarters.\n\n\nAs always, should you have any questions, you can post in our\n[Webmaster Help Forum](https://support.google.com/webmasters/go/community).\n\n\nPosted by [John Mueller](https://twitter.com/johnmu?rel=next),\nfan of command lines and APIs, Google Zuerich"]]
