OAuth Security Enhancement

Beginning on May 1st, 2025, JH is enhancing jXchange SOAP API security by transitioning to OAuth 2.0 instead of username and password pair. This change ensures alignment with modern cloud security standards.

We have created a landing page with valuable information, dates, questions, and videos to help a consumer prepare for this rollout. Please visit: SOAP Authentication Update
