Integrate HTPBE PDF tamper detection API into Spring Boot apps

Original: PDF Tamper Detection API for Java: Spring Boot Integration Guide

Short summary

This guide walks through integrating HTPBE's PDF tamper detection API into a Spring Boot 3.2+ application, covering RestClient-based submission, typed DTOs, configuration properties, error handling with Spring Retry, and a DocumentGate pattern that maps verdicts to ACCEPT/REJECT/REVIEW decisions. The two-step API flow (POST /analyze, GET /result) returns intact, modified, or inconclusive verdicts. The article targets fintech, banking, and insurance backends where document integrity at ingress is critical.

  • •Step-by-step Spring Boot integration for HTPBE PDF tamper detection API with RestClient and typed DTOs
  • •Two-step flow: POST /analyze returns check ID, GET /result returns verdict (intact/modified/inconclusive)
  • •Includes DocumentGate pattern mapping verdicts to ACCEPT/REJECT/REVIEW for institutional-origin documents
