Only 7% of hotel PMS vendors offer self-serve API docs
A new audit of 343 hotel PMS vendors lands with a number that should make every hotelier stop and think: only 7% publish fully self-serve API documentation. That is it. Seven in a hundred. The 2026 PMS API study scores 18 profiles and the spread is brutal, from 80.0 for Mews down to 26.3 for Oracle Opera 5.
What does this mean in practice? If your PMS hides its API behind a sales call, an NDA and a six-week integration project, every tool you want to plug in, from a revenue manager to an upsell engine to a payments layer, becomes a negotiation instead of a weekend. Self-serve docs are the difference between a hotel running its own stack and a hotel waiting for a vendor ticket.
My read: the 7% figure is not a scandal, it is a map of where the value is moving. Vendors that open their APIs attract builders, and builders bring hotels the tools they actually ask for. If you are choosing a PMS this year, put API openness on the shortlist next to price and support. It will matter more than either one by 2027.
