I want an SMS extension/module for Magento 2, and I want to use local companies SMS gateway. I couldn’t find such extensions available for my country and if they are, they are very expensive because they aren’t developed or not using local SMS gateways.
So I have decided to code myself, but now I am lost at this point as where to begin? I did find some tutorials on google, but they were not for beginners, I am looking for a documentation here e.g. as its available for Android development.
Is there any such detailed documentation available for Magento extension development?
Please let me know.
