SNAP API Run-Time is not downloadable. Run-time API is embedded in the SNAP Pro WordPress plugin and will allow plugin to autopost to the additional networks. It can’t be used for any other purposes.
SNAP API Light is a downloadable package that contains only API libraries. API libraries can be called directly with credentials or using the settings array. You need to generate and bring appropriate credentials for each network or settings array by yourself.
SNAP API Pro is a downloadable package that contains API libraries and management panel. You can use management panel to create settings array and use it to call API.
Main Question: Can this product read messages from my database? Can this product save/read my settings from the database? Can it post to multiple accounts simultaneously? Can I set the delay? How can I set a schedule to automatically post and repost my messages?
This product is an API.
API is not an extended script that uses DB connections, can save user info, or do some “re-posting functionality”
Simply API is a “black box” that you provide with the destination, credentials and message. API will post this message to your destination using your credentials. That’s it, nothing more, nothing less.
You can call it as many times as you like with different destination and credentials ad it will post to different accounts or pages.
It’s up to you where you would like to save login info (database, textfile, cloud, etc..).
It doesn’t read messages from the DB, it does not schedule posts or re-posts, it does not do any other functionality. API is a library that you can wrap your own code around.
Our WordPress plugin is a very good example of kind of code could be written around the API.
PS: “PRO” API is a little bit more complex, so instead of sending destination and credentials each time you can just give it the settings array with all credentials and destinations and then just supply the message.
Universal API is a yearly subscription. If you bought SNAP Pro WordPress plugin with two standalone API files for $49.95 within a year, you can get a $49.95 discount here: http://www.nextscripts.com/snap-api/upgrade/
Universal API has two ways of calling it.
You can do something pretty similar to what you did with standalone API files. You can see the new code samples here: http://www.nextscripts.com/google-plus-automated-posting/
Alternately you can use it with settings array as shown on examples here: http://www.nextscripts.com/snap-api/
