Update Multiple Datastreams Simultaneously

Update multiple Datastreams of a single device with one GET request. It can help with saving the data volume for cellular devices.

Use such update for Map Widget in Blynk.Console so that all datapoints have same timestamp for data and coordinates.

Batch update

GET https://{server_address}/external/api/batch/update?token={token}&{pin1}={value1}&{pin2}={value2}

This operation updates multiple Datastreams of a single device with one GET request. Example: https://blynk.cloud/external/api/batch/update?token=bFFtSHNCZZDWQ__Zs96cP5jLMhLoJofg&v1=33&v2=44

Path Parameters

Name	Type	Description
token	string	Device AuthToken
pin	string	Virtual Pin
value	string	The desired value of the Datastream. Will be parsed based on the Datastream data type (int, double, string) and bounded with min / max values of datastream settings. In case value doesn't match the Datastream type error will be returned.

200 Success

OK

400 Could not find a device token or Wrong pin format or Value doesn't match the Datastream data type

{"error":{"message":"Invalid token."}}

or

{"error":{"message":"Wrong pin format."}}

or

{"error":{"message":"Value doesn't match the Datastream data type"}}

You can get the Device auth token in Device info.

You can also use Blynk.Edgent API to send data with the same timestamp.
