Hi Vunda

The nature of a Web API is its openness to be used by any software. As a 
start, I would start in trying to understand how such an API works, 
which is based on "HTTP REST" principles.
REST in layman's terms: http://www.looah.com/source/view/2284
REST basics (IBM developers): 
https://www.ibm.com/developerworks/library/ws-restful/index.html
Specification for DHIS2: 
https://dhis2.github.io/dhis2-docs/master/en/developer/html/dhis2_developer_manual_full.html

As an example, the programming language Python can be used, which is 
installable on any system and is on Ubuntu by default. DHIS2 supports 
the transportation format JSON. There's a new library on github 
(https://github.com/dhis2/dhis2-python, but have not tried it yet) or 
you can write your own.
So a basic procedure would be:

myscript.py
1. load a configuration of both APIs (username, url, passwords)
2. make a GET request to a specific endpoint of MoH API
3. validate, transform,... the received data
4. make a POST request to another specific endpoint of your other 
instance's API

and then install a cronjob which calls this script with "* * * * * 
python myscript.py"

Further extensions could be logging to a file and a mail notification if 
something goes wrong.

I hope this can help a bit.

Best regards
David
