The integration of Ukrposhta is the selection of a branch by index directly in the basket, an approximate calculation of the cost by weight and dimensions, and the formation of the shipment from the admin instead of re-entering data in the carrier's office. We connect the tariff classes in separate lines - express to the branch, standard to the branch, courier to the address - because the deadlines are different, but the word "Ukrposhta" is the same. We keep the directory of branches and indexes in our table and update it with a background task according to the schedule. The process takes 3-10 business days and begins with a free verification of your checkout.

What's included
Complete list of work and what you get as a result
Choosing a department from the list with a search by city and index — the buyer does not type the index by hand, and it is the handwritten index that most often breaks the shipment
Tariff options in separate lines: express to the branch, standard to the branch, courier to the address - the buyer sees the difference in terms, not one name of the carrier
Approximate calculation of the cost based on weight, dimensions and declared value - the amount is visible before registration, not through a call from the manager
Automatic updating of the department directory and indexes on a schedule — a new department appears at your disposal without manual import
Forming a shipment from the admin and printing accompanying documents — the manager does not go to the carrier’s office and does not type the address a second time
Transmission of the track number in the order and in the letter to the buyer - the question "where is my parcel" reaches the manager less often
Post-payment check for your product: is your calculation scenario supported for the selected tariffs - we fix the answer before launch
International shipment script with a list of attachments — if you need it; we transfer the data in the format accepted by the carrier
End-to-end verification on a live order together with your manager: from the shopping cart to the printing of documents and the track number in the letter
Technical transfer: access, short written instructions for your processes, 30 calendar day guarantee for completed work

Who it's for
Situations where this service delivers results
Scenario 1 of 5
The product is light, and the carrier's commission eats up the margin
Spices, cosmetics, small accessories, sets — where the parcel weighs hundreds of grams, the difference in the tariff is noticeable on each order. In the measured spice store, Ukrposhta is the third option next to Nova Poshta and self-delivery, and the buyer decides for himself what to pay for.
We'll review your situation in a free audit
Scenario 2 of 5
Your customers live not only in regional centers
In a small town or village, the post office is often the only delivery point within a radius of several kilometers. Without Ukrposhta in the checkout, such a buyer either writes to the manager or leaves. This is not an increase in traffic - it is a removed reason for not placing an order.
Scenario 3 of 5
A commercial carrier is already there, a second selection line is required
A working combination that we see more often than others. In the two garden tool stores measured, four carriers are simultaneously on the delivery and payment page, among them Ukrposhta. Adding a second checkout to an already normal checkout costs less than remaking a checkout from scratch.
Scenario 4 of 5
The manager interrupts the address in the carrier's office every time
The order has arrived - further clarification of the index in the messenger, manual entry in the office, printing, copying the track number back to the order. A few minutes for each parcel and exactly one way to make a mistake in each of the four steps.
Scenario 5 of 5
You ship abroad
Then it is better to collect the recipient's data in Latin and the list of attachments using a form on the website, and not by correspondence. This is a separate script with its own rules, and it should be laid before the launch, and not after the first refusal of admission.
Free shipping script check
Ukrposhta is connected differently than commercial carriers: it has its own directory, its tariff classes and separate rules for international shipments. The check shows which set you really need.
What we measure
What rates do you really need?Express to branch, standard to branch, courier — all three were turned on in the measured store. Each additional tariff is a separate calculation and a separate line in the checkout.
Directory of departments and indexesWe check whether the list of branches and postal codes is pulled up automatically. The index entered manually by the buyer is the most common reason for a rejected shipment.
What the buyer sees at checkoutThe shipping price must be visible or honestly marked as an estimate. We saw "0 hryvnias" in the checkout on a carrier whose information page on the same website said 35–80 hryvnias.
International shipmentsIf you are shipping abroad, this is a separate scenario with a customs declaration and a list of attachments. It is better to take it into account before, and not after, the launch.
What about postpaidPost-payment conditions at Ukrposhta differ from those of commercial carriers - we check whether your scenario is supported at all.
What you get
Real checkout report: what shipping methods the site currently offers and at what prices.
A list of Ukrposhta tariffs that you should enable.
Evaluation of works and term with division into obligatory and desirable.
A conversation for 20-30 minutes with the manager who ships the order.
Timeline: 1-2 working days
Why is it free
Because the check takes several hours, and without it you can't see whether it's a configuration of an existing module or a development from scratch.
What's next
After the inspection, we give an estimate and a deadline. If manual registration in the carrier's office is enough for your volume, let's say it directly.
Short form: your contact and site URL
Contract, act and 30-day warranty
Every project gets a written contract: scope, deadlines, amount, acceptance procedure. After delivery — act and invoice, then 30 calendar days of warranty.
Sole proprietor & bank transfer
The contractor is a registered sole proprietor. Payment by invoice with closing documents.
Rights & access — yours
Code, design and materials transfer to you after full payment. Domain, hosting, repository and analytics are registered to you.
Client portal instead of email chains
During the project you get access to a portal: contracts, invoices, acts and project status in one place.
European clients
Among our work — projects for Norway, Bulgaria, Moldova and Spain.
Verifiable numbers
Every case in the portfolio comes with a link to a live site and a technical measurement.
Audit first, then pricing
There is no price list on the site intentionally: the scope of the same work differs multiples between clients.
We say "no" when unsure
If the task isn't ours or the deadline is unrealistic — we tell you upfront.
What affects the price
Why two seemingly identical tasks are priced differently
How many tariff classes are includedOne class per branch — one calculation and one row in the basket. Three classes — three calculations, a selection rule between them, and three test scenarios. This is the most common difference between a short job and a long one.
Is it necessary to create shipments from the adminIf the carrier's office is enough for the manager, we don't do this block at all. If you need to print documents directly from the order - access rights, templates and error handling from the API when data is not passed are added.
Checkout status at the startIn a store where there is already one carrier with a normal selection of branches, Ukrposhta is lining up. If the checkout shows "0 hryvnias" for paid delivery, the calculation itself must first be put in order - otherwise the new carrier will simply add the second wrong number.
Platform and versionOpenCart and WooCommerce often have a ready-made module, and the work is reduced to configuration and verification. A self-written checkout or showcase on Next.js means that we write API calls under your code.
International shipmentsSeparate script: list of attachments, recipient data in Latin, declaration. It almost doubles the amount of testing, so you need to decide whether to take it or not during the inspection, not in the middle of the work.
Scope of live testingOne control shipment with your manager is included. Running all tariffs with real parcels of different weights takes extra days, and they usually pay off.

Process steps
Transparent stages with approval at every step
Total duration:3–10 days
1
Checkout and access
1-2 working days
Let's see what the site gives now: what are the delivery methods, with what prices, where does the index come from. In parallel, we accept access to the API from your account and fix the list of tariffs that we enable.
2
Directory of departments and tariff classes
1-3 working days
We create our own table of departments and indexes, set the background task of updating according to the schedule and separate the tariffs in separate lines with an explanation of the term. Right here it is decided what to show by default.
3
Calculation of the cost in the basket
1-2 working days
Weight, dimensions and declared value are linked to the calculation, the amount is displayed with the mark "approximate". We separately describe the behavior when the API did not respond: the cart should not fall with it.
4
Formation of shipments and track numbers
1-3 working days
The button for creating a shipment in the admin, printing accompanying documents, recording the track number in the order and in the letter to the buyer. Errors from the carrier are shown to the manager by text, and not by a silent failure.
5
Live run and transmission
1 working day
We make a real order together with your manager — from choosing a department to printing documents. Next, access, instructions and warranty period.
Technologies & integrations
What we build on and what it connects to
Stack
Ukrposhta's API is the only source of the directory of branches and indexes; its limit is that the carrier calculates the final amount upon receipt
OpenCart 3 / 4 — there are ready-made modules, but not every developer has a build for 4.x; we fix the version before the start
WooCommerce - plugins exist, some have not been updated for years; we take the one that was read in the code
Next.js — there is no ready-made module, we write API calls by hand; instead, the checkout is not limited to someone else's template
PHP and MySQL - we keep the directory in our table, instead of pulling the API for each rendering of the shopping cart
The background task of updating the directory is on a schedule and with a log; if the carrier has not responded, the cart is working on the previous version of the list

Integration against manual registration in the carrier's office
How this option differs from the alternative
Manual registration in the officeOur approach
Who enters the addressthe manager clarifies the index in the correspondence and types it by handthe buyer chooses a department from the list with a search by city and index
Relevance of the directorythe carrier's office is always fresh - the manual method does not lose herebackground update on schedule, with a log of failed attempts
Delivery cost for the buyerthe amount is named by the manager, and often the buyer does not know it at allweight and dimensions reference point is visible before registration
Time for one packagere-entering the same data on each orderthe data is already in the order, all you have to do is click "create shipment" and print it
When is more profitableunits of orders per month - the integration will not pay offfrom several shipments per day and in the presence of a second carrier
What we need from you
We can't start without this — best to prepare in advance
1Access the Ukrposhta API from your account — the carrier draws up the contract for you, not for the contractor.
2Access to the site and admin with rights to install modules, plus a test environment if you have one.
3The list of tariffs that we enable and the selection rule between them: what to show the buyer by default.
4Sender data: address, postal code, contact person, phone.
5The typical weight and dimensions of shipments or the formula by which they are calculated from the goods in the basket.
6An order manager for two or three hours - he is the one who goes through the live script and tells where it is inconvenient.
If something is missing — let us know, we'll help you gather it or do it as a separate task.
FAQ
Most frequently asked questions — with concrete answers
How is Ukrposhta more difficult than a commercial carrier in terms of integration?
Two things: a directory and tariff classes. The address of the branch here is tied to the postal code, not to the number of the branch in the city, so the search in the basket should be done both by the name of the settlement and by the index. And tariffs are divided into express and standard with different delivery times. If you combine them into one line of "Ukrposhta", the buyer will not receive the term for which he expected, and the claim will go to you, not to the carrier.
Can you show the buyer the exact shipping cost?
Approximate - yes, according to weight, dimensions and declared cost. The exact amount is calculated by the carrier when receiving the shipment, and no module will bypass this. Therefore, we derive the calculation with the honest mark "approximate". What should not be done is to show "0 UAH" when delivery is paid: we saw exactly such a checkout in a store whose information page on the same domain called 35-80 UAH.
We already have Nova Poshta — will it be faster?
Yes, and it is noticeable. The most expensive part of the work is to get the cart delivery step right: calculation, validation, behavior when the API is not available. If this has already been done, Ukrposhta is placed as the second block in the finished scheme. The reverse is also true: if you plan both carriers, take them in one job - the checkout is processed once, not twice.
Is postpaid supported?
Technically yes, but conditions differ from commercial carriers and depend on the tariff and type of product. That's why the checkout check is done before the estimate: we see if your billing scenario is even supported for the rates you want to enable. Learning about pre-launch restrictions costs hours, after launch - canceled orders.
And international shipments?
This is a separate scenario and needs to be addressed early on. A list of attachments, recipient data in Latin and a customs declaration are required. Technically, we collect this data in a form on the website and transmit it in a format accepted by the carrier. We do not undertake the customs clearance itself - it is your area of responsibility, and we do not pretend that we know how to close it.
How long does the work last and why is the sum of days by stage greater than the deadline?
The term is 3–10 working days. By stages: checkout check 1–2 days, directory and tariffs 1–3, cost calculation 1–2, creation of shipments from admin 1–3, live run 1. The amount looks larger, because the stages are partly parallel: while the directory is being updated, the calculation is already being written. The lower limit of 3 days is real when access is available from the first day and one tariff class is enabled.
Who updates the branch directory after launch?
No one's hands. The directory resides in your database and is updated by a background task on a schedule - this is a conscious decision, not an API saving. If you drag the carrier on every cart render, your cart will stop working exactly when someone else's server goes down. With a local copy, at such a moment, the buyer simply sees a slightly older list of branches, and the order is processed.
And if there is no ready-made module for our platform?
We write API requests ourselves - this is done on Next.js showcases and self-written checkouts. The scope is larger than the box module setup, but there is no third-party code that will one day be deprecated. And a separate practical tip: before installing a plugin from the catalog, we open its code and look at the date of the last modification. The number of installations does not say anything about the vitality of the module.
When do you not need integration?
When the number of shipments is one per month, then the carrier's office is cheaper than any development, and we will say it during the inspection, not after the bill. Another case: all goods are bulky or expensive, and Ukrposhta's tariffs are not suitable for them. Then an extra line in the cart only adds to the buyer's doubts at the moment when he almost clicked "check out".
Give a link to the checkout — let's start with the check, not the estimate
In 1-2 working days, we will return with a report: what the site gives the buyer now, which Ukrposhta tariffs it makes sense to enable for you, and how much work it is. If the carrier's office is enough for your volume, you will hear it in the first email.
From measured casesMeasurement 07/31/2026: 48 products and 18 categories
There is no price list on the site on purpose: the same work differs several times over between two clients, and a “from” figure explains nothing in that case. First a free audit — we count your pages, duplicates and speed — then we name the sum and the deadline and fix both in the contract.
