I am new to using the SDK and working with widgets. I've done context apps before but now it seems we have to transition to using widgets. I'm taking it one step at a time, and the first step is to get connected to some ION API's. But all the examples are all for the M3 API's, which seem to be vastly different than the CSD/SX.e API's. It's really hard to follow the M3 examples because there are references to terms I am unfamiliar with. Has anyone here used the SDK to make widgets for CSD/SX.e, and if so can you point me toward some code examples for using the API's? Or perhaps at the very least, other ION API's like IDM, or Data Fabric? Something other than M3, since I don't have access to any of the documentation for M3 API's so that I can figure out what the examples are doing? Thanks!
