It is a daunting task to handle different courier companies. But it is unavoidable due to limited serviceability of different service providers in different locations / regions. Due to this reason, it would be very difficult in my practical experience to integrate APIs of different companies into my online shopping portal.

 

And bug fixing, debugging in case of server outages, API changes would render my tracking tools useless and leading to frustrated customers. Of course i can't blame them because it's my responsibility as the owner to provide them the tracking feature obviously. For example, a website like USPS is the most popular shipping and mail company in the world after China Post. It offers a free and public API for tracking shipments and mail shipped through USPS registered services. It is prone to change sometimes and sometimes, it may break existing applications that are using their old API. I have faced this problem personally and lead to hundreds of my customers ranting on our facebook page.

 

To avoid all these problems, DTDCtrack.in handles tracking functionality of hundreds of different courier and shipping companies and unifies them into a common gateway. You can just embed their widgets and implement tracking features on your website or store.
