Custom Trunkrs integration development
Appfront builds custom Trunkrs integrations that automatically register your orders for same-day and next-day delivery across the Netherlands and Belgium. Through the Trunkrs API and webhooks, you create shipments, generate labels and send real-time track & trace back to your customer. You save manual work on every order and give your customers fast, reliable delivery without your team having to update statuses by hand.
What is a Trunkrs integration?
Trunkrs is a last-mile delivery service for the Netherlands and Flanders that operates as an IT platform: it connects webshops to a network of regional transport partners who physically deliver the parcels. Trunkrs specialises in fast delivery, same-day and next-day, where a customer can order until 23:59 and the parcel is delivered the following evening.
In practice, a custom integration means: programmatically registering orders from your webshop as shipments with Trunkrs, generating shipping labels and linking them to your packing slip, automatically sending the track & trace link to your customer, and writing delivery status back into your order or customer system via webhooks. This keeps your team in control without manually updating statuses.
Appfront builds in line with the official Trunkrs API documentation and the OWASP ASVS security standard. We align the integration, error handling and fallback logic with your actual order flow, so the integration grows with your range and remains reliable during peak volumes around the holidays.
Automatically creating shipments
Orders from your webshop are registered directly as shipments with Trunkrs, with no manual retyping or separate shipping tools. Address, contact details and parcel information flow across automatically, ready for same-day or next-day delivery.
Real-time track & trace
Webhooks send every status change straight back to your system: registered, out for delivery, delivered. Your customer automatically receives a track & trace link, and your customer service team sees the current status without logging in to Trunkrs.
Labels within your order flow
Shipping labels are retrieved via the API and linked directly to the correct order, ready to print at your packing station. No separate exports or duplicate entry: warehouse staff pack and apply the right label in one step.
Our development process for Trunkrs integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your order flow, webshop platform and warehouse process through to go-live and ongoing management, every step is aimed at an integration your team can understand and trust.
We map out which orders you want to ship via Trunkrs, which data from your webshop or ERP is needed for a shipment, which shipping methods apply and how status updates should flow back.
We design the integration architecture, choose the right authentication and draw up an error-handling strategy.
Implementation with automated tests, structured logging and monitoring. You see working builds along the way.
Controlled go-live with data validation and a safety net, followed by ongoing management and further development.
What a Trunkrs integration delivers in practice
Every Trunkrs integration is set up specifically for your order flow, shipping methods and adjacent systems. Below are the features we most often deliver for webshops and retailers that use Trunkrs as part of their delivery process.
Trunkrs API integration
A direct integration with the Trunkrs Client API from your webshop, ERP or WMS. Authentication, shipment creation and retrieval of labels and statuses run automatically, with proper error handling and retries so that no order falls through the cracks.
Creating & cancelling shipments
Orders are submitted to Trunkrs via the API as shipments containing the address, contact details and parcel information. If an order is changed or cancelled, we automatically update the shipment too, so your shipping records always match the actual orders.
Label generation
For each shipment we retrieve the shipping label via the API and link it to the correct order. The label is ready to print at your packing station, optionally together with the packing slip, so that packing and labelling become one smooth step.
Track & trace for your customers
Once a shipment has been registered, we link the track and trace information to the order and automatically send the customer a tracking link. Your customer service team sees the same status in your own system, without having to log in to Trunkrs.
Delivery times & delivery options
We connect to Trunkrs' same-day and next-day delivery options and display the right choice at checkout based on postcode and order time. This way, customers know in advance when their parcel will arrive and can make an informed choice for fast delivery.
Webhooks & status updates
Trunkrs sends every status change through webhooks, from submitted through to delivered. We validate and process those updates in your system, trigger delivery emails and keep your order statuses up to date, without anyone having to poll manually.
Typical use cases in practice
A Trunkrs integration looks very different from one organisation to the next. We see a number of patterns recur, and for each of them we have a working setup that takes account of your order flow, shipping methods and the feedback of delivery statuses.
Webshops & e-commerce
Online retailers who want to stand out with fast delivery. Orders are automatically submitted to Trunkrs for same-day or next-day delivery, labels flow to the packing station, and the customer receives a track & trace link straight away. See also our e-commerce development and API integrations.
Retail & D2C brands
Brands that sell directly to consumers and see delivery as part of their brand experience. An integration that writes the delivery status back into your own system ensures that customer emails, the my-account area and customer service always show the current status, in your own house style.
Food & fresh products
Providers of fresh produce, meals or other time-sensitive goods for whom same-day delivery makes the difference. The integration selects the right delivery option based on postcode and order cut-off time, and processes status updates so you can act in good time when deviations occur.
Fulfilment & 3PL
Fulfilment partners and 3PL providers that ship for multiple webshops. A single central Trunkrs integration, connected to your WMS, registers shipments per client, generates labels and passes statuses back to the correct customer system, scaling across your entire order stream.
Technology we use
We build Trunkrs integrations with the official Client API and webhooks, combined with the backend stack that suits you. The precise choice depends on your webshop platform and warehouse systems, so that your own team can manage or further develop the implementation.
Why choose Appfront for your Trunkrs integration?

Security and privacy in Trunkrs integrations
A delivery integration processes your customers' personal data: name, delivery address, email and phone number. That data is sensitive and may only be used for its intended purpose, which is delivering a parcel. Appfront builds to the OWASP ASVS: we process only the address and delivery data Trunkrs needs, keep nothing longer than necessary, and encrypt the data traffic between your system and the API.
We keep the API credentials for Trunkrs in secure vaults, never in code or configuration files, and we validate every incoming webhook before processing the status. We document the data flows so your records of processing activities are complete and you can demonstrate compliance with the GDPR. That keeps the integration secure, even when credentials are rotated periodically.
More on our security approach: information security policy and CVD policy.
- GDPR-compliant processing of address and delivery data
- Data minimisation: only what Trunkrs needs
- Encryption in transit (TLS 1.2+) and at rest
- Validation of incoming webhooks
- API credentials in secure vaults, with periodic rotation
- Automatic retries and dead-letter queues
- Monitoring and alerting for anomalies
- Documentation for your record of processing activities
Frequently Asked Questions About Trunkrs Integrations
Answers to the questions we are asked most often about Trunkrs integrations.
A Trunkrs integration is a technical link between the Trunkrs API and your own system, such as your webshop, ERP, WMS or order platform. Through the Trunkrs Client API, you create shipments programmatically, generate shipping labels and retrieve the status of parcels. Webhooks send real-time status updates back to your system. An integration can be simple, such as automatically registering orders for next-day delivery, or comprehensive, with shipments, labels, track and trace and status processing fully automated within your order flow.
Trunkrs suits webshops and retailers that want to offer fast delivery to customers in the Netherlands and Flanders. Trunkrs provides same-day and next-day delivery: a customer can order until 23:59 and the parcel is delivered the following day between 17:00 and 22:00. Trunkrs operates as an IT platform that connects webshops with regional transport partners. For shipments outside the Netherlands and Flanders, or for parcels to the Wadden Islands, we will work with you to identify a suitable additional carrier.
A simple integration (registering orders as shipments, retrieving a label and feeding back the status) can go live within a few weeks. More complex scenarios, involving multiple shipping methods, fallback to other carriers, returns and deep WMS or ERP integration, generally take longer. After an intake meeting in which we review your order flow and systems, we will give you a realistic estimate.
We work with the official Trunkrs Client API and webhooks, combined with the backend stack that suits you: Node.js, Python, PHP, .NET, Ruby or Go. Authentication runs through your Trunkrs API credentials. For creating shipments, generating labels and processing status updates, we connect to your existing webshop or order platform, or build a middleware layer that decouples your systems from the API.
The cost depends on the complexity of your order flow, the number of systems to connect, the required handling of labels and status updates, and the amount of custom business logic. Ongoing management, monitoring and support also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation.
Yes. A delivery integration processes personal data such as your customers' names, addresses and contact details. Appfront builds to the OWASP ASVS: API credentials in secure vaults, validation of incoming webhooks, scoped permissions and encrypted data traffic. We process only the data required for delivery and document the data flows so that your records of processing activities remain complete and you can demonstrate compliance with the GDPR.
Yes. Appfront regularly takes over existing shipping integrations, even where they were originally set up by another party. We review the API integration, label handling, webhook configuration and error handling, document the current setup and propose improvements. From that point on, we can manage adjustments, extensions and monitoring, including timely rotation of API credentials.
Trunkrs is a good fit for webshops and retailers that want to offer fast delivery to their customers in the Netherlands and Flanders. Typical users are e-commerce businesses looking to stand out with next-day or same-day delivery, D2C brands, food suppliers of fresh products, and fulfilment or 3PL providers that ship for multiple webshops. To establish the right fit, we look at your shipping volume, delivery area and the systems Trunkrs needs to integrate with.
