I am looking for below features in YAF

• Open APIs,
• Analytics Reports,
• Integration with Mobile application,
• Sending notifications

Can some one guide me whether we have these features ? IF yes document around it.

Thanks

Open APIs

There is only a basic webservice. Example here...

But you could easily extend it yourself, if needed.

Analytics Reports

No

Integration with Mobile application

No, but YAF starting with Version 2.3.0 has a responsive Layout

Sending notifications

If you mean email messages then yes.
