So Yahoo Pipes is closing down.
As of August 30th 2015, users will no longer be able to create new Pipes. The Pipes team will keep the infrastructure running until end of September 30th 2015 in a read-only mode. You can download your Pipe definition by specifying your Pipe-ID (_id) and the output format (_out=json) to the following end-point: http://pipes.yahoo.com/pipes/pipe.info For e.g: http://pipes.yahoo.com/pipes/pipe.info?_id=ZKJobpaj3BGZOew9G8evXg&_out=json
Please post any questions you have related to this announcement on the Yahoo Developer Forum for Pipes. The Pipes team thanks you for support and cooperation.
