About the technology
What SOAP is
SOAP, or Simple Object Access Protocol, is an XML-based messaging standard for structured communication between applications. It commonly uses HTTP or HTTPS, but can also run over other transport protocols. WSDL describes the service contract, while XML schemas define message structure and data types.
Where it is used
SOAP remains important where strict contracts, formal governance and reliable interoperability matter. Companies use it for internal services, partner connections and long-running enterprise systems.
- Banking and payment integrations
- Insurance and public-sector services
- SAP and ERP communication
- B2B partner and supplier interfaces
- Legacy application modernization
Ecosystem and tooling
SOAP projects often combine WSDL, XSD, XML namespaces and schema validation with WS-Security, WS-Addressing and WS-ReliableMessaging. Common tooling includes Apache CXF, JAX-WS, Spring Web Services, .NET WCF and SoapUI. Experts also work with API gateways, message brokers, certificates and CI test pipelines.
When expertise matters
Freelance expertise helps when a service contract is difficult to change, an integration has inconsistent XML behavior or a migration must preserve existing consumers. In Berlin, specialists may support local enterprise teams on-site or work remotely with distributed product, security and operations groups.
- Define or revise WSDL contracts
- Diagnose namespace and serialization errors
- Implement authentication and message signing
- Test partner services and edge cases
Project deliverables
A capable specialist can produce service contracts, generated client or server bindings, integration adapters and test fixtures. They can document endpoints, map XML schemas to domain models and establish monitoring for failed messages. Strong delivery also includes compatibility checks before changes reach production.
What strong specialists bring
The best professionals understand both the protocol and the business systems behind it. They read XML and WSDL closely, trace messages across transports, and distinguish application faults from network or certificate problems. They also know when SOAP is the safer choice than REST and can explain trade-offs clearly to technical and non-technical stakeholders.
Frequently asked questions
Curious about SOAP? Here are the answers that come up again and again.
SOAP is used to exchange structured XML messages between independent applications. It is common in banking, insurance, government, healthcare and enterprise systems where formal contracts, security standards and reliable processing are important.
SOAP provides a formal service contract and a broad set of WS-* standards for security, addressing and reliability. REST is usually simpler and more flexible for web APIs, but SOAP can be a better fit when strict governance or established enterprise integrations are required.
A strong SOAP specialist usually works with WSDL, XSD, XML namespaces and schema validation. Useful adjacent skills include Java or .NET, Apache CXF or Spring Web Services, certificate management, OAuth or WS-Security, databases and integration testing.
The right level depends on the scope, not just the age of the service. A straightforward client connection may need focused integration knowledge, while changing shared WSDL contracts, securing messages or migrating legacy services requires a specialist who has handled compatibility and production troubleshooting.
Yes. SOAP work is often suitable for remote collaboration because contracts, schemas, logs and test environments can be shared securely. On-site sessions in Berlin can still help when specialists need access to restricted systems or close coordination with enterprise and compliance teams.
Ask how the specialist has handled WSDL changes, namespace mismatches, XML validation failures and fault responses. A high-quality SOAP professional can explain message flow clearly, show a disciplined testing approach and describe how certificates, retries and backward compatibility are managed.
Simple Object Access Protocol remains relevant when an organization already depends on formal service contracts or WS-* standards. For a new lightweight public API, REST or another modern approach may be more practical, but the decision should follow security, governance and interoperability needs.
Before starting SOAP work, clarify the available WSDL files, schema ownership, transport, authentication method and test endpoints. Freelancers should also ask about generated bindings, release constraints, partner dependencies and whether remote access to sensitive enterprise systems is possible.
The average hourly rate of freelancers in Berlin, Germany who have used SOAP in their recent projects is 90 €, which corresponds to a daily rate of about 719 € based on an 8-hour working day.
