Niccolò Cacace contributed to the pagopa/pn-b2b-client repository by delivering end-to-end enhancements for probing data access and multi-tenant M2M credential management. He implemented secure authentication using AWS Cognito and KMS, expanded telemetry retrieval, and improved scenario state management to support onboarding and observability. His work included refactoring core REST clients to use ResponseEntity, introducing DPoP support, and aligning naming conventions for maintainability. Using Java, Spring, and Cucumber, Niccolò automated test coverage, stabilized polling and error handling, and enabled robust producer keychain workflows. The depth of his contributions reduced architectural debt and improved security, reliability, and onboarding efficiency.

Feb 1, 2026February 2026 (pagopa/pn-b2b-client) — Key outcomes: Feature delivery, bug fixes, and business impact. Key features delivered: - PROBING_COMPLETE_PROCESS Scenario added for QA-11072. - M2M Keys and Keychains: KeysClient, ProducerKeychainsClient, M2MProducerKeychainsClient, and related BFF components. - Tenant Context: creation and use in M2M flows. - M2M Users Client and retrieval: UsersClient, M2M_V3_GET_USERS, M2M_V3_GET_USER scenarios. - Core client refactor: performOperation via ResponseEntity; rename UserClient -> M2MUsersClient and KeysClient -> M2MKeysClient. - M2M V3: Producer Keychains Users Associations (create/get/verify/delete) with polling. - Producer Keychains M2MV3 Client Integration (QA-12314): new client methods, resolver support, polling/config, tests scaffolding; property base path updates; renamed to M2MV3ProducerKeychainsClient and M2MV3UsersClient; added DPoP support and Interop integration. - Testing and resilience: test syntax fixes, polling fixes, header removal steps, and HTTP status alignment (400/401/404). Major bugs fixed: - Producer Keychains M2MV3 Client Integration Bug Fix: remove integrated KeysClient/Step/feature from M2MProducerKeychainsClient to align with M2MV3 structure. - Polling logic and polling response support improvements. - Test syntax and header-related fixes: And->When in users.feature, M2MV3UsersClient scope, id values, and IllegalStateException messaging. - Token/header handling: 400/401/404 status adjustments across QA-12314 scenarios. Overall impact: - Accelerated multi-tenant M2M capabilities with a coherent M2MV3 architecture; improved reliability through polling, snapshot handling, and header control; enhanced test coverage and automation; reduced architectural debt via consistent naming and ResponseEntity-based operations. Technologies/skills demonstrated: - Java/Spring, ResponseEntity-based REST client, multi-tenant TenantContext, DPoP, RSA-based key generation, Cucumber-based test automation, Maven-based CI/CD, refactoring for maintainability. Business value: - Faster onboarding of B2B clients with robust M2M credential and producer keychain support; improved security posture and reliability; lower maintenance costs due to architecture alignment and test automation.

Jan 1, 2026January 2026 (2026-01) – pagopa/pn-b2b-client: Delivered end-to-end probing data access enhancements, introduced secure authentication groundwork, and improved testing quality and reliability. Key features include expanded probing data retrieval for producers, e-services catalog, service profiles, and telemetry data, with enhanced scenario state management and interval controls. Implemented token-based authentication for probing clients using AWS Cognito and KMS groundwork, including bearer token handling. Fixed client-side error handling in probing scenarios and stabilized tests by updating status codes (e.g., UPDATE_PROBING_STATE and UPDATE_OPERATIONAL_STATE from 404 to 400). Result: higher observability, stronger security posture, and more reliable validation of e-service configurations, enabling faster business decisions and smoother onboarding of new services.
