01 / The problem

Every new channel means: typing everything in again.

A new property comes in. So: enter it in the CRM, upload it to ImmobilienScout24, to Immowelt, to Kleinanzeigen, to your own website. Photos five times, description five times.

Then the price changes. Or the car is sold. Or the item is out of stock. And somewhere the old version is still online, because nobody can keep up.

The result: hours of data maintenance that are missing in sales. And customers enquiring about an offer that no longer exists.

There is another way. Set it up once, stay in sync.

02 / The causes

Why data maintenance eats so much time and still produces errors

Four places where companies lose time, enquiries and trust every single day.

  1. Every platform wants the data differently

    ImmobilienScout24 expects OpenImmo, mobile.de the DAT standard, Amazon the SP-API. Without a translation layer in between, all that is left is copying and adjusting by hand.

  2. Your systems do not talk to each other

    CRM, ERP, shop and portals each keep their own stock. They are reconciled via exports, CSV and Excel, whenever someone has the time.

  3. Manual work produces errors

    A typo in the price, a forgotten availability, a missing image. Each of these errors costs enquiries and damages your reputation on the portal.

  4. More channels means more staff

    As long as every platform means manual work, you stay on a few portals. Reach you could have remains unused.

03 / The solution

Your data flows automatically. You keep the overview.

We connect your system with every platform where your customers search. You maintain data in one place, the rest happens by itself.

  1. Real-time synchronisation

    Changes go out to all connected platforms immediately. Price changed, vehicle sold, item out of stock: everywhere at once.

    • No outdated offers
    • No overselling from old stock
  2. Data mapping

    Your data fields are translated to the requirements of each platform and validated before publication.

    • OpenImmo, DAT, SP-API
    • Categories and attributes
  3. Error handling

    If a portal stalls, the system retries automatically and alerts immediately when there is a problem.

  4. Analytics and monitoring

    A dashboard shows all sync processes, failure rates and run times. Problems surface early, usually before your customers notice them.

  5. Secure and GDPR-compliant

    Encrypted connections, secure authentication and data transfer in line with the GDPR.

  6. Clean documentation

    Complete API documentation and technical guides, so your development team always knows what is running.

  7. Scales with you

    Whether ten listings or ten thousand products: the infrastructure grows with your inventory.

  8. Support around the clock

    Technical support and monitoring 24/7. We take care of incidents, often before you notice anything.

Knowledge

XML & API integration: why professional interfaces matter

The backbone of efficient operations

In a connected business world, XML feeds and API integrations are the backbone of efficient processes. Whether product data for online marketplaces, listings for property portals or vehicle inventory for automotive marketplaces: automated data transfer saves time, removes sources of error and lays the foundation for business models that can grow.

Weber Media builds bespoke interfaces that connect your existing systems with external platforms. Without you having to replace your software.

Standards and systems we connect

Our experience covers REST APIs, SOAP web services and GraphQL endpoints as well as industry standards: OpenImmo for real estate, the DAT standard in automotive, the SP-API at Amazon.

Every integration comes with error handling, automatic retries and real-time monitoring, so your data flows run reliably around the clock.

  • CRM: Salesforce, HubSpot, Pipedrive, Propstack, onOffice, Flowfact
  • ERP and inventory: SAP, Microsoft Dynamics, DATEV, JTL, Lexware, Billbee
  • PIM: Akeneo, Pimcore, InRiver

What automated feeds deliver economically

The biggest saving is time: product maintenance, price changes and stock reconciliation run automatically instead of tying up hours every week. Your team takes care of pricing strategy, assortment and customers, not copying.

Add to that fewer errors. Wrong prices, outdated availability and missing images lead to complaints, goodwill discounts and lost trust. Automatic validation before publication catches them.

And more reach: when an additional platform no longer means manual work, you list where your customers search. Multichannel sales without multichannel effort. With a single source of truth, so customers see the same correct information on every portal.

API first: advantages for mid-sized companies

An API-first approach makes new sales channels quick to connect, keeps prices and stock consistent across all platforms and frees your team from manual data entry. Especially in mid-sized companies, where resources are limited, professional interface development often decides between growth and stagnation.

From Hamburg for Germany, Austria and Switzerland

10 / FAQ

Frequently asked questions about XML & API feeds

Your question is not listed? We will answer it directly in the strategy call.

What does an XML or API integration cost?

That depends on how many platforms are connected, which standards they use and whether data flows in one or both directions. In the strategy call we analyse your systems free of charge and you receive a clear recommendation with a budget range before you decide.

Which platforms can you connect?

More than 80 platforms, including ImmobilienScout24, Immowelt, mobile.de, AutoScout24, Amazon, eBay, Kaufland, OTTO, Idealo, Google Shopping, Shopify, WooCommerce and Shopware. Plus CRM, ERP and PIM systems. If a platform has an interface or a feed, we can usually connect it.

How much effort is involved for me?

Little. You give us access to your system and the platforms and explain how your business works. We take care of analysis, design, build, testing and operation.

Do you support OpenImmo and the DAT standard?

Yes. OpenImmo XML for property portals and the DAT standard for vehicle marketplaces are part of our daily work, as are the IS24 API, the mobile.de interface and the Amazon SP-API.

What happens when a portal changes its interface?

Our monitoring watches all sync processes around the clock. If a transfer fails, the system retries automatically and we are notified immediately. If a portal changes its interface, we adapt the integration.

Can I not solve this with an off-the-shelf plugin?

For a single channel, sometimes. As soon as several platforms, custom data fields, a CRM or an ERP are involved, plugins quickly reach their limits. Then you need clean mapping, validation before publication and monitoring. That is exactly what we build.

Do I have to switch my existing software?

No. We connect the systems you already use, for example Propstack, onOffice, Flowfact, your dealer management system, JTL or SAP. You keep maintaining your data where you are used to.

How secure is the data transfer?

Transfers run over encrypted connections with secure authentication and in line with the GDPR. We only grant access with the rights the interface actually needs.

Do you only work in Hamburg?

Our headquarters are in Hamburg, and we serve companies across Germany, Austria and Switzerland. Integration projects run smoothly remotely.
