/external/api/data/get?token={token}&period={PERIOD}&granularityType={TYPE}&sourceType={SOURCE_TYPE}&tzName={tzName}&format={FORMAT}&output=FILE&pin={pin}
Use case example:
You live in Sydney and have garage door opener and want to get an exact time you departed today in one file. The accuracy you need is up to 1 minute and it should be in "YYYY-MM-DD HH:MM:SS" format.
Garage door opener is Blynked and it uses Datastream with ID 20 and virtual pin 6 for open/close commands. Also you want to get the list of all the events occured during this period. So API request for this case looks like:
https://blynk.cloud/external/api/data/get?token=HjKjfij84050fege&period=DAY&granularityType=MINUTE&sourceType=AVG&tzName=America/New_York&format=ISO_SIMPLE&sendEvents=true&output=FILE&dataStreamId=20
JSON Output example:
{
    "meta":
    [
        {
            "name": "data_stream_name",
            "type": "String"
        },
        {
            "name": "ts",
            "type": "UInt32"
        },
        {
            "name": "value",
            "type": "Float64"
        }
    ],
​
    "data":
    [
        {
            "data_stream_name": "",
            "ts": 2021-05-14 12:25:00,
            "value": 1.6100000000000003
        }
