Get Native Balances

There is an option getNativeBalances when creating or editing a Stream. It is a list of native balances calls for specific addresses.

You can get Native Balances (ETH/BNB/MATIC and many more) of addresses that appear in your Webhook. They are very similar to Triggers.

Native Balance Trigger

"getNativeBalances": [
selectors: ["$fromAddress", "$toAddress"],
type: 'tx'
  • selectors is a list of valid Selectors, for each selector you will get the native balance in the Webhook.
  • type for which part of the Webhook you want to select the addresses. Valid Types and also internalTxis allowed!


The Webhook introduces a new field nativeBalances that has the balances uniquely ordered by the triggers:
