Attachments Rewrite API
We are transforming our legacy SOAP/XML attachment process into a modern REST-based API called Document Processing—a redesigned solution that streamlines real-time exchange of supporting documentation between firms. This upgrade enables clients to reduce operational risk, enhance efficiency across their workflows, and offers:
- Simplified integration through a modern JSON-based design
- Enhanced transparency with clear status updates
- Compliance assurance with industry-leading security standards
