Package Delivery tracking

Package Delivery tracking

Hi,
I'm new to Zoho Creator. Does anyone do delivery tracking automation for purchases in Zoho Creator apps. I am trying to accomplish this using the invoke_url functions, but my problem is finding an appropriate API to call. All the Third party APIs I am finding are aimed at ecommerce, and my only alternative is addressing every first party API (USPS, UPS, Fedex, etc). I am not opposed to that, but for some like Amazon Logistics, I cant find an API at all.

Sorry if this is off-topic, but if there is a recommendation for an API or a more 'Zoho' oriented approach, I would really appreciate some pointers. Anyone go down this road before?
