Returns changes for each access key in a given block. Multiple accounts can be queried by passing an array of account_ids.


Supported on NEAR (mainnet) only.


  • changes_type- string - The type of changes
  • account_ids- array - An array of account ids
  • finality- string - The assurance that the transaction cannot be altered, reversed, or canceled after they are completed. For finality=final, it means that it has been validated on at least 66% of the nodes in the network and for finality=optimistic, it uses the latest block recorded on the node that responded to the query passed
  • block_id- int/string - The block id which could be either a block number or block hash

Note: You can only use one parameter, either finality or block_id. The block_id param can take either the block number or the block hash as an argument.


  • block_hash - The hash of the block this transaction was associated with
  • changes - An array of changes that occurred in the account during the transaction
    • cause - The reason behind the account changes
      • type - The change causing factor in an account. It could be transaction_processing or receipt_processing
      • tx_hash/receipt_hash - There can be two values returned dependent on the change-causing factor. For transaction_processing, the returned value is tx_hash, which represents the hash of the transaction. For receipt_processing, the returned value is receipt_hash, which represents the hash of the receipt.
    • type - The type of changes occurred in the account
    • change - The changes occurred in the account during the transaction
      • account_id - The identifier for the account
      • public_key- The public key of the signer
      • access_key- The access key for authenticating the account
        • nonce- The number of transactions made by the sender prior to this one encoded as hexadecimal
        • permission- The type of permission
