BAPI on Post Incoming Payment (F-28) Enquiry

Question

Hi all,
I try to look for BAPI on F-28 and I had search for many info. However, I found that 1 thread saying that we can have 'BAPI_ACC_GL_POSTING_POST' to do.
Refer to this site:
bapi is used to 'post incoming payments (t-code F-28)'
However, I found that the BAPI is used for transaction FB50. Generally, I use the F-28 to post incoming payment for AR. So I am not so sure that the BAPI can work.
Besides that, I found another thread claim that no BAPI for the F-28. Refer to this site:
https://www.sdn.sap.com/irj/sdn/profile?userid=677412
As my research, I cant find the appropriate BAPI. Please give me some idea on how the BAPI work, and any correct BAPI can be used? Frankly, I a bit confused now.
Thanks and regards.
Cheers,
Isaac
