Looking for someone experienced with API integration. Need a USPS rate calculator API, and UPS rate calculator API on my web site. There is a need for some customization so PHP skills may come in handy.
This is how I need it to work. A user inputs the ship from zip code, ship to zip code, and weight. The results will show:
1) the UPS Ground Rate using the inputed parameters,
2) the total of
a) UPS Ground Rate from the user's ship from zip code to a default zip code, plus
b) the USPS Priority Mail rate from a default zip code to the users zip code, plus
c)a handling fee based upon the inputed weight
and 3) the difference between #1 and #2 above.
It must be easy to make changes to the handling fee.
