Please find attached my entire changes ...
The attachment includes:
2. API documentation (sites_web_domain_backup.html)
3. API navigation file (navigation.html)
4. API example file (sites_web_domain_backup.php)
I have tested these API changes on my production server and everything works fine.
I just made a slight change to the proposed code though:
Instead of return true, I changed to return SUCCESS
and Instead of return false, I changed to return FAIL
Let me know if there any comments or suggestions ..
