Dexcom
Dexcom is a leading medical device company that develops, manufactures, and distributes continuous glucose monitoring (CGM) systems for people with diabetes. The company's wearable sensors stream real-time glucose data to mobile apps, dedicated receivers, and connected health platforms. Dexcom exposes a public developer program that lets approved third parties retrieve CGM data (estimated glucose values, events, calibrations, alerts, devices, and data range) through an OAuth 2.0 secured REST API, with a sandbox for development and a production environment for live patient data.
Dexcom publishes 7 APIs on the APIs.io network, including Alerts API, Authentication API, Calibrations API, and 4 more. Tagged areas include Continuous Glucose Monitoring, Diabetes, Digital Health, Glucose, and Healthcare.
The Dexcom catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Dexcom’s developer surface includes authentication, documentation, getting-started guide, sandbox, support, and 15 more developer resources.
