device_dataStreamId - send id of the datastream

device_dateCreated - send device creation date

device_pin - send current pin of datastream

device_pinValue - send current (last) pin value of datastream

device_clientType

device_country

device_state

device_zipCode

device_metadata_X where X is metadata identifier - value of device metadata. Example: {device_metadata_1}

device_tags - comma-separated device tag names.

timestamp_unix - timestamp of webhook triggered in epoch format

timestamp_iso8601 - timestamp of webhook triggered in ISO8601 format

user_id

Blynk support multiple values in a single pin

Type of datasream should be only string, method GET

Use in sketch Blynk.virtualWrite(V17, "7", "6", "5");

Custom JSON:

{
  "value0": "{device_pinValue[0]}",
  "value1": "{device_pinValue[1]}",
  "value2": "{device_pinValue[2]}"
}

Result after triggering webhook:

Trigger a webhook from the hardware

Request Type – select supported :

Value – select from (manual scroll or quick search by typing)

Value – select from (manual scroll or quick search by typing)

Placeholder – scroll and select the object(s) you want to add to your code

Placeholder – scroll and select the object(s) you want to add to your code
