Interhyp

Interhyp AG is Germany's leading platform for residential mortgage financing (Baufinanzierung), connecting homebuyers and partners with the best financing options by comparing offers from more than 500 loan partners. Through its Developer Studio (developer.ehyphome.de) Interhyp publishes a partner-facing REST API surface — most notably the Submission API — that lets brokers, referrers and platforms integrate mortgage submission workflows, financing applications, documents, logbooks and pre-submission checks directly into their own applications. The API is designed "API First" and "Mobile First", secured with OAuth 2.0 JWT bearer tokens plus an Api-Key header, uses cursor-based pagination, RFC 7807 problem+json error responses and traceId request tracing. Interhyp is part of the ING Group and operates the broker brand Prohyp.

Interhyp publishes 8 APIs on the APIs.io network, including commands API, documents API, financing-application API, and 5 more. Tagged areas include Company, Fintech, Mortgage, Lending, and Baufinanzierung.

Interhyp’s developer surface includes documentation, getting-started guide, changelog, signup flow, support, authentication, sandbox, and 16 more developer resources.
