API expert needed to link Zoho to courier companies

We are using an inventory software Zoho inventory and we need an expert to help us create an API with the courier's website such that information like Name, shipping address, phone numbers, etc are pushed to the courier's platform so we do not need to manually enter it. Once the tracking number is available, it should be pushed back to Zoho inventory. When the item is delivered, the status should also be pushed to zoho inventory. I have the APIs for both platforms.
