WS2 therapytimeline is currently used to fetch CGM, IOB, bolus, and NON-ControlIQ basal data. The WS2 therapytimeline API endpoint is excruciatingly slow to respond to queries at times -- Tandem's API frontend sometimes returns http 500's since it times out querying its backend. It can sometimes take multiple minutes to get a response as it refuses to return results entirely. The end data also needs to be heavily processed.

Equivalent data should exist in the ControlIQ therapy_events endpoint, which contains at least Basal, Bolus, and CGM data.
