Are you also troubled by the integration of enterprise applications across different platforms and languages? The latest version of API7 Enterprise Edition can now support and integrate with SOAP (Simple Object Access Protocol), providing you with a perfect solution.

SOAP achieves cross-platform and cross-language application communication by offering an XML-based messaging mechanism. It possesses rich security, reliability, and scalability, making it suitable for various complex enterprise integration scenarios. The latest version of API7 Enterprise Edition can perfectly support and integrate SOAP, enabling enterprises to easily connect their existing SOAP services with other modern applications and systems, achieving efficient and stable application integration.

Choose API7 Enterprise Edition and obtain a seamless and comprehensive solution, without worrying about complex enterprise integration scenarios anymore!

Introduction to SOAP

SOAP realizes cross-platform and cross-language communication by encapsulating messages in XML (Extensible Markup Language) format for transmission. Based on HTTP or other protocols, it allows applications to interact between different operating systems and development environments.


SOAP has the following characteristics:

  1. Reliability: SOAP provides a set of reliable message delivery mechanisms to ensure the integrity and reliability of the message. By using an XML-based message format and a built-in error-handling mechanism, SOAP can handle transmission errors in the network, thereby ensuring the correct delivery of messages.
  2. Security: SOAP supports multiple security mechanisms, such as encryption and digital signatures, to ensure the security of the communication process and the confidentiality of data. By using security extensions and standard security protocols like HTTPS, SOAP can handle the transmission and storage of sensitive information in an enterprise-level integration.
  3. Scalability: SOAP has good scalability, allowing custom messages and data types. By using WSDL (Web Services Description Language) to describe service interface and message structure, SOAP can adapt to different business requirements and application scenarios.

Many enterprises have been using SOAP services for a long time and hope to integrate them into modern applications and systems. For example, converting SOAP to REST can facilitate users to access traditional Web services in a RESTful manner, reducing the development cost of SOAP clients. However, the cost of directly transforming SOAP services is too high. Consequently, there is an urgent need for a lightweight and efficient solution provided by API management.

API7 Achieves Zero-Cost Conversion to SOAP

API7 Enterprise Edition will soon support the forwarding of RESTful HTTP requests to the soap-proxy process, so as to realize the conversion between RESTful requests and SOAP requests without any modification to the original SOAP service. This enables enterprises to easily integrate existing SOAP services with API gateways to achieve more efficient and stable application integration. Therefore, enterprises can choose the most appropriate protocols for communication according to actual needs, and achieve interoperability between different systems.

Advantages of using API7 SOAP plugin and proxy:

  • No need to manually parse or import WSDL files
  • No need to define conversion templates
  • No need to write any conversion or coupling code
  • WSDL URL can be bound to any route and updated at runtime, configuration taking effect dynamically without restarting
  • Identify service URLs (upstream address) automatically and use them as SOAP upstream without parsing and configuring the WSDL file

The traditional proxy method, either providing conversion templates or writing conversion code, requires users to deeply analyze WSDL files. There is a non-negligible development cost. However, API7 Enterprise Edition provides an automated way to analyze WSDL files and transformation logic for each operation automatically, eliminating development costs for users. With the automatic conversion function of API7, users can convert existing SOAP services to REST APIs simply by configuring the WSDL URL. This general program requires no customization for specific needs and can be applied to any Web service. As a result, it can greatly reduce the workload of developers and improve the efficiency of API development for enterprises.

API7 support for SOAP will bring many benefits to various industries and application domains. For example, financial institutions such as banks, insurance, and payment institutions often use the SOAP protocol for secure data transmission and interaction. By using API7, these institutions can easily connect existing SOAP services to the gateway, thereby realizing centralized and unified gateway management and lowering the threshold for use by callers. At the same time, using the security features provided by API7, such as authentication, access control, and TLS (Transport Layer Security), these institutions can protect sensitive financial data.

Considering historical reasons and cost considerations, SOAP services are not always suitable for full refactoring as RESTful services. Therefore, SOAP-to-REST is in great demand from many enterprise users. However, because SOAP and REST have different architectures and communication styles, refactoring SOAP services into RESTful services is very costly.

API7 provides a wealth of features such as security, reliability, and scalability, as well as efficient API management tools and analysis functions, to help enterprises achieve efficient and stable application integration.
