Solution Overview

Problem

Existing API proxy generation processes are manual, error-prone, and lack standardization, leading to inefficiencies, increased development time, and security vulnerabilities across different enterprise departments.

Innovation Solution

An automated and repeatable process for generating API proxies using an API proxy generation engine that processes an OAS document to create standardized API proxies, reducing manual data entry and enhancing security by generating API proxies and backend service code.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual API proxy generation processes are used, then flexibility in customization is maintained, but errors increase and development time extends

Engineering Contradiction:

ImproveaccuracyVSAvoiddevelopment time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs automated API proxy generation without requiring manual intervention. The generation engine automatically processes API specifications, generates proxy code, and configures proxies, eliminating human error and accelerating development while maintaining high accuracy through standardized automated processes.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If manual API proxy generation processes are used, then customizations can be made individually, but resource redundancy increases across departments

Engineering Contradiction:

ImprovestandardizationVSAvoidresource redundancy

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The automated generation engine serves multiple enterprise departments with a single unified system. It processes different API specifications and generates customized proxies for each department while using shared resources and standardized processes, eliminating resource redundancy and promoting cross-departmental standardization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If automated API proxy generation is implemented, then development time is reduced, but implementation complexity increases

Engineering Contradiction:

Improvegeneration efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The automated generation engine acts as an intermediary between API specifications and proxy implementations. It handles the complexity of code generation, configuration, and validation internally, presenting a simple interface to users while managing sophisticated automated processes in the background, thus improving productivity without exposing system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Techniques are described for using an application programming interface proxy and backend implementation. An example method can include accessing an open application programming interface document. The method can further include generating a shell script based at least in part on the open application programming interface document, the shell script associated with an application programming interface proxy, the application programming interface proxy for accessing a backend service. The method can further include processing a request for accessing the backend service. The method can further include causing, using the shell script, access to the backend service via the application programming interface proxy based at least in part on the request.
