New Confirmed Internal Transactions For Specific Amount

Through this endpoint customers can create callback subscriptions for a specific event and "amountHigherThan" value. In this case the event is when there are new confirmed internal transactions and the amount is equal or higher than a value, specified by the customer. By creating this subscription the user will be notified by Crypto APIs 2.0 when that event occurs, filtered for the specified amount. Being confirmed means that the transactions are verified by miners and added to the next block

Supports Callback Functionality Single Result - This endpoint returns only one single result. POST /blockchain-events/{blockchain}/{network}/subscriptions/internal-transactions-for-specific-amount

Path Parameters

Required
blockchain string

Represents the specific blockchain protocol name, e.g. Ethereum, Bitcoin, etc.

Example : ethereum

Possible Values : ethereum ethereum-classic binance-smart-chain tron
Required
network string

Represents the name of the blockchain network used; blockchain networks are usually identical as technology and software, but they differ in data, e.g. - "mainnet" is the live network with actual data while networks like "testnet", "ropsten" are test networks.

Example : ropsten

Possible Values : mainnet testnet mordor nile goerli
