FAQ
Which courier and carrier APIs do you support?
I have hands-on experience integrating DHL API, FedEx API, UPS API, USPS API, Aramex API, and several regional carriers. If you are using a different shipping provider, feel free to message me with the API documentation and I will confirm before you order.
Can you integrate shipment tracking and real-time delivery status updates?
Yes. I implement real-time shipment tracking by connecting directly to the carrier's tracking API. This includes live delivery status updates, estimated delivery time, and webhook support where the carrier provides it — so your system or app stays updated automatically.
Do you provide shipment label generation and PDF label printing?
Yes. Shipping label generation is included in all packages. I integrate the carrier's label API to generate labels in PDF or ZPL format, ready for thermal printers or standard printers — depending on your courier's supported formats.
What technology stack do you use for the API integration backend?
I primarily build the backend using Node.js and Express.js with REST API architecture. I can also integrate into existing Angular or React frontends. For the database layer I work with MySQL and MongoDB. If you have an existing stack, I will adapt to it.
Can you fix bugs in my existing shipping or logistics API integration?
Yes. Bug fixing and optimization of existing courier or carrier integrations is a service I offer. Whether it is broken webhook handling, incorrect label data, failed shipment requests, or authentication errors — share the issue and I will diagnose and fix it.
Do you support multi-carrier rate comparison and carrier selection logic?
Yes. In the Standard and Premium packages I can build multi-carrier rate comparison — fetching shipping rates from multiple couriers like DHL, FedEx, and UPS simultaneously so your system or customer can select the cheapest or fastest option automatically.
Will I receive documentation and source code after delivery?
Yes. Every delivery includes clean, well-commented source code and API documentation covering endpoints, request/response structure, and setup instructions. You will be able to maintain and extend the integration yourself — or I am available for ongoing support.
