Writing Points to a Measurement
This code writes data points to a measurement (my Swagger). It requires a CollectorUUID and MeasurementUUID to be filled in. The collector UUID can be retrieved by listing the collectorslisting the collectors. The measurement UUID can be retrieved from where it was created: Manage Measurementscreate measurements.
POST https://historian.mycompany.com:18000/api/collector/collectors/{collector_uuid}/points (replace {collector_uuid} with your collector UUID)

resp = session.post(url, json=points, timeout=60)
resp.raise_for_status()
return resp.json()
