Working with the partner API for business

Do you send packages from the USA for clients?

If orders are becoming numerous, manual processing starts taking up time and gets in the way of business growth. Prostobox.com offers a partner API exactly for such cases — a simple way to automate shipping and handle a large volume of shipments without unnecessary routine.

The partner API is suitable for businesses that want to work faster, more accurately, and scale without increasing their team.

Which business is the partner API suitable for

The partner API is designed for businesses with regular shipments. If you send packages not occasionally, but continuously - the API will significantly simplify your work.

The API is suitable if you are:

  • an online store with delivery of goods from the USA
  • a buyer or shopping assistant
  • a seller on marketplaces
  • an owner of a Telegram store
  • a B2B seller (vitamins, clothing, footwear, electronics)

As a rule, the API is used by companies that have dozens or hundreds of shipments per month.
If there are only a few packages - it is more convenient to work through your personal account. If the volume grows - the API becomes the logical next step.

What does the partner API provide

The partner API allows you to connect your system directly to Prostobox.com - without manual data entry and constant monitoring.

With the API, you can:

  • automatically create parcels
  • transfer order data
  • receive tracking numbers
  • track delivery statuses
  • work with shipments without logging into your personal account

All processes run automatically - you save time and reduce the number of errors.

How the partner API works

The logic is simple and transparent:

  1. The customer places an order with you
  2. The data is automatically transferred to Prostobox.com
  3. The package is created without manager involvement
  4. You receive a tracking number
  5. Delivery statuses are updated automatically

No spreadsheets, copying, or manual verification of each package.
