Hi,

We write a custom module, and use flash to invoke custom function we wrote.

(follow this guide [https://www.wowza.com/docs/how-to-extend-wowza-streaming-engine-using-java](https://www.wowza.com/docs/how-to-extend-wowza-streaming-engine-using-java))

Now we want to wirte a mobile application by GoCoder SDK, but it seems has no functionality to invoke custom function ?

(by reading [https://www.wowza.com/resources/gocodersdk/docs/1.0/api-reference-ios/](https://www.wowza.com/resources/gocodersdk/docs/1.0/api-reference-ios/))

Please advise.

Thanks

Thank you for bringing your request to our attention. We are indeed working on the ‘two-way metadata’ feature that will allow you to send an event from gocoder and catch that on the Server side by invoking a custom function. Please expect this feature to arrive very soon in the upcoming releases.
