Interhyp AG is Germany's leading platform for residential mortgage financing (Baufinanzierung), comparing offers from 500+ loan partners. It is part of ING Group and runs the broker brand Prohyp.
Through its Developer Studio (developer.ehyphome.de) Interhyp publishes partner-facing REST APIs — the Submission API (financing applications, applicants, estates, households, financial standings, offers, submissions, logbooks, commands, pre-submission checks) and the Submission Documents API — secured with OAuth 2.0 JWT bearer tokens plus an Api-Key header, using cursor pagination, RFC 7807 problem+json errors, and a traceId for support correlation.
