Eventually I would like to hire an iOS and Android developer to create an app. Essentially, the app allows users to log-in to a server to send and receive messages with other users.
I have a limited budget and would like to do parts myself, primarily creating an API for this server and writing documentation for it.
I am curious: while I have been working with PHP and MySQL for many years, this will be my first API. Would these technologies be well suited for an API? Also, are there any general tips and feedback for starting an API.
Even if I have to subcontract parts of the API development, I strongly feel creating a fully functioning and well documented API and providing polished mockups to an app developer would not only greatly reduce project scope for the app developer, but create well defined goals for the developer that will help save time and money.
