SOAP (obsolete, but still used in banking/state. sector)

SOAP (obsolete, but still used in banking/state. sector)

Despite the fact that REST and gRPC have taken a leading position in modern architectures, SOAP is still used in a number of critical integrations - especially the banking sector, government platforms and large corporate solutions. We provide SOAP protocol support, including cXML messaging, WSDL documentation, and certificate authorization.

This allows you to connect the platform to third-party systems where there are no alternative interfaces yet, and maintain compatibility with established processes.

Where SOAP is used

Scope	Integration examples
Bank gateways	Integration with payment systems, account verification, reports
State services and registers	Data transfer to tax, fiscal portals, licensing authorities
Corporate ERP	Communication with 1C: Enterprise, SAP, Oracle via SOAP services
Legal documents	Exchange of legally significant XML messages (contracts that close acts)
Certificate Authorization	SOAP Request Signing, PKCS12 Encryption, and TLS

Implementation features

The exchange format is XML over SOAP 1. 1 / 1. 2
WS-Security support: digital signature, tokens, certificates
WSDL description of interfaces and data types
Reliable exchange: clear error scheme, repetition of requests, validation of schemes
XML can be transformed into REST or GraphQL if necessary

Benefits of using SOAP

Compatibility with state regulators, banks and large integrators
Stability and strict contract description through WSDL
Support for complex security requirements (certificates, encryption)
Ability to work through intermediate gateways and converters
Complete query/response logic with data structure validation

Where especially important

State or municipal accounting systems
Banking and payment institutions
Companies required to use certified SOAP exchange
Integration with "old" ERP, where there are no REST/gRPC interfaces

SOAP is not about fashion, but about reliable compatibility. If your task is to integrate with government agencies, banks or mature corporate systems, SOAP support can be critical. We are ready to ensure such compatibility.
