I/O POST/GET Going Away in 7.14?

Is it true that the I/O Post/Get is being removed and being replace with API with 7.14? If so, does anybody have an example of how to toggle the Output pin using Curl and the API? The API documentation for I/O pin configuration is sparse IMO.

Yes, check Implementation of Read-Only System Files and Mobile and I/O POST/GET Service Removal with RutOS 7.14

For API documentation use https://developers.teltonika-networks.com/reference/rutx50/7.13.1/v1.5/input-output#post-io-id-actions-change_state
