The problem

Your customers want Europe. Opening a warehouse there is not the answer.

🏗️

A warehouse per country

Each new origin means a lease, staff and a carrier contract before the first package. Most couriers never get past the business plan.

🔀

A partner panel next to yours

Using a foreign forwarder by hand means your team works in two systems, and your customers' tracking stops at the border.

🧾

Customs paperwork at volume

Dozens of consolidated shipments a week, each with its proforma. Typed by hand, it is where mistakes and delays come from.

📉

Margins you can't see in time

If rates are checked after the fact, a carrier change eats the margin of a whole week of shipments.

What you can automate

Everything your account does on the web, from your own system

The API is your Resendify account, programmable. Same permissions, same plan prices — so anything you click today can run on its own tomorrow.

🏷️

Your address in every warehouse

Fetch your personal address and customer code for each of our 10 countries, ready to paste into any checkout.

📦

Declare inbound packages

Create each expected package with store, order number, carrier, tracking and expected arrival — straight from your order flow.

🛒

Buy for me, programmatically

Send a product link and price; we place the order in the store. The payment request comes back with the provision and your plan's handling fee.

🔎

Status, photos and history

List and search every package by status, warehouse, tracking or order; read its photos, full status history and per-leg tracking events.

🧩

Consolidation

Ask us to merge several checked-in packages into one, choosing the consolidation type and leaving instructions for the team.

💶

Instant price quotes

Prices for any weight, size and postal code without creating a package — sorted by cheapest or fastest, with the carrier's own estimate.

🚚

Shipping options and booking

Get the live options for a package in the warehouse, choose one, add premium insurance and book it to any saved address.

🧾

Customs proforma

Send the item list with HS codes and origin together with the booking. It is validated before anything is contracted.

👛

Payments from your balance

Pay shipments and pending requests from your wallet, and read your full payment history for accounting.

📇

Address book

Add, edit and set default delivery addresses within your plan's quota — with a safety step when an edit would invalidate a pending quote.

🪵

Pallet quotes

Request a pallet quote with dimensions and value; our team prices it (within 72 hours at most) and the price appears on the same request.

🔔

Real-time notifications

Your server is told about every status change, new payment request and completed payment the moment it happens.

End to end

One package, from store to door, without opening the panel

This is the whole life of a package and what your system can do at each step. Each stage arrives as a notification, so your platform reacts instead of polling.

  1. 1Created

    Declared

    Your system declares the purchase — or asks us to buy it — the moment the order is placed.

  2. 2In warehouse

    Checked in

    Arrival with photos. You can check contents remotely and forward the proof to your own customer.

  3. 3Consolidating

    Grouped

    Optional: several packages become one box to cut the international rate.

  4. 4Payment pending

    Booked

    Options priced, carrier chosen, customs proforma sent and validated.

  5. 5Paid

    Paid

    Charged to your balance only if the amount is exactly the one you expected.

  6. 6Shipped → Delivered

    On its way

    Carrier tracking per leg until delivery, pushed to your system as it happens.

Built for production

Why teams that integrate it don't go back to the panel

An API that touches money and customs has to be safe to automate. These are the details that make it so.

🧪

A real sandbox

Any call can run in test mode: validated exactly like live, with a simulated answer — nothing is created, charged or shipped.

🛡️

Price guard on every payment

You send the amount you expect to pay. If the price moved, nothing is charged and your system decides what to do.

✍️

Signed, retried notifications

Every notification is signed so you can verify it came from us, retried if your server fails, and carries an id to ignore duplicates.

⚖️

Same prices as your plan

The API does not add a price layer: quotes and charges are your plan's, exactly as in the web panel.

🧾

Customs checked before booking

When a route crosses customs, the proforma is validated before the shipment is contracted — not after it is stuck.

🤖

Readable by people and AI

Standard REST and JSON with a machine-readable specification: your developer, or an AI assistant, can work with it from day one.

Workflows

How a courier runs a new origin through the API

The model most couriers use: we receive and consolidate at origin, ship to your hub, and you keep the customer and the last mile.

Your customer's purchase → expected package

Your customer buys and gives you the tracking, as they do today. Your system declares the package with that tracking and your own customer reference, so it is checked in to the right person.

  • Search by tracking, order or your reference
  • Check-in photos to show your customer
  • Status pushed into your own tracking pages

Consolidated departures to your hub

Your system groups the checked-in packages of a warehouse and books one shipment to your hub address, with the customs proforma built from what each customer declared.

  • Consolidation requested when your departure rule says so
  • Proforma validated before booking
  • Paid from balance with a price guard

Rates in your own price list

Quote any weight and size from each origin in real time and keep your public price list honest. Your margin is calculated on today's rate, not last month's.

  • Quotes without creating a package
  • Cheapest or fastest first
  • Your plan's prices, same as the panel
Getting started

How couriers get started

  1. 💬

    1

    Tell us what you want to automate

    Your system, your volume, the warehouses you would use and where your packages go. A person from sales replies.

  2. 🔑

    2

    We enable the API on your account

    With the plan that fits your volume. You receive the documentation and your developer has everything to start.

  3. 🧪

    3

    Test everything in sandbox

    Every action can be rehearsed with real validation and a simulated answer: nothing is created, charged or shipped.

  4. 🚀

    4

    Go live

    Your system declares, consolidates, ships and pays on its own, and hears about every change the moment it happens.

Receiving countries

Warehouses and receiving points across key global markets

We can receive your packages in multiple strategic countries, giving you access to stores, suppliers and marketplaces that would otherwise be hard to reach internationally.

Your customer, your brand, our origins

The customer relationship stays yours. They buy, they hand you the tracking, they follow the package in your system. We are the origin operation behind it: receiving, photographing, consolidating and handing over to the carrier.

On business memberships the sender name on packages leaving our warehouse can be your company's, at no extra cost. And because notifications arrive the moment each status changes, your tracking pages stay current without anyone checking a second panel.

The last mile — from your hub to your customer's door, and customs at destination — remains your operation, as it is today.

  • Your customer relationship and pricing stay yours
  • Sender name customised on business memberships
  • Origin operation by us; hub, customs at destination and last mile by you

What to settle in the sales conversation

Today the API works on your company's account: every package is yours, told apart by tracking number and the references you send. If you need each of your customers to have their own code at our warehouses, tell us in the form — that is a setup we look at with you, not something to assume.

Volume matters too: tell us your packages per month, your peaks and the origins you want to open first, so the plan and the operation are sized before your first departure.

We do not promise transit times. Options show the carrier's own estimate, which we do not control.
