An integration aggregator is a vendor that sells one API which fans out to many EHRs behind the scenes — examples include Redox and Health Gorilla. Instead of negotiating and building a separate connection to each hospital's system, you integrate once and the aggregator normalizes authentication, data models, and the endless site-by-site quirks. The payoff is speed: integrations that would otherwise take quarters can come together in weeks, and you gain breadth across many health systems quickly.
The trade-offs are structural, not incidental. The aggregator becomes another business associate sitting in the protected health information (PHI) path, which means another BAA to execute and another vendor whose security posture you inherit under the HIPAA Security Rule (45 CFR §164.312). There is per-connection economics to model, and the depth of any given integration is bounded by what the aggregator chose to expose — if you need a field or workflow they have not surfaced, you are waiting on their roadmap, not your own.
For a telemedicine product, the practical decision is rarely all-or-nothing. A common pattern is to use an aggregator for breadth — connecting to the long tail of health systems efficiently — while building direct FHIR or HL7 integrations for the flagship accounts where you need maximum depth, control, and economics at scale. The common mistake is treating the aggregator as a way to forget about integration complexity entirely; the complexity is still there, just relocated to a partner whose limits and pricing you must understand before you commit your roadmap to them.
