It's just optional in the case that you fetch all timeseries definitions with a HTTP GET. If you want data points you have to specify it.</P> Fri, 22 Jun 2018 13:15:30 GMT wolfgang_beer 2018-06-22T13:15:30Z https://community.dynatrace.com/t5/Dynatrace-API/API-Aggregation-Settings/m-p/32020#M56 <P>Is it possible to call more than one aggregation dataset in one Timeseries API call. Basically the "aggregationType " parameter having more than one value. I noticed that this parameter is optional, if you leave it out does it bring back all the values or just the average. The manual doesn't make this clear.</P> <P>Thank you.</P> Tue, 25 May 2021 14:44:24 GMT https://community.dynatrace.com/t5/Dynatrace-API/API-Aggregation-Settings/m-p/32020#M56 rb0c70091 2021-05-25T14:44:24Z https://community.dynatrace.com/t5/Dynatrace-API/API-Aggregation-Settings/m-p/32021#M57 <P>No that's not possible.
