  "account" : "xrb_1e5aqegc1jb7qe964u4adzmcezyo6o146zb8hm6dft8tkp79za3sxwjym5rx"  
}

Account history

Reports send/receive information for an account. Change blocks are skipped, open blocks will appear as receive (unless raw is set to true - see optional parameters below). Response will start with the latest block for the account (the frontier), and will list all blocks back to the open block of this account when "count" is set to "-1".

Request:

{  
  "action": "account_history",  
  "account": "xrb_1ipx847tk8o46pwxt5qjdbncjqcbwcc1rrmqnkztrfjy5k7z4imsrata9est",  
  "count": "1"
}

Response:

{  
    "account": "xrb_1ipx847tk8o46pwxt5qjdbncjqcbwcc1rrmqnkztrfjy5k7z4imsrata9est",   
    "history": [   
        {   
            "type": "send",   
            "account": "xrb_38ztgpejb7yrm7rr586nenkn597s3a1sqiy3m3uyqjicht7kzuhnihdk6zpz",   
            "amount": "80000000000000000000000000000000000",   
            "local_timestamp": "1551532723",   
            "hash": "80392607E85E73CC3E94B4126F24488EBDFEB174944B890C97E8F36D89591DC5"   
        }   
    ],   
    "previous": "8D3AB98B301224253750D448B4BD997132400CEDD0A8432F775724F2D9821C72"   
}   

If the count limit results in stopping before the end of the account chain, then the response will also contain a previous field (outside of the history field) which contains the block hash that would be next to process if count was larger.

Optional parameters:

• raw: if set to true instead of the default false, instead of outputting a simplified send or receive explanation of blocks (intended for wallets), output all parameters of the block itself as seen in block_create or other APIs returning blocks. It still includes the "account" and "amount" properties you'd see without this option. State/universal blocks in the raw history will also have a subtype field indicating their equivalent "old" block. Unfortunately, the "account" parameter for open blocks is the account of the source block, not the account of the open block, to preserve similarity with the non-raw history.
• head: instead of using the latest block for a specified account, use this block as the head of the account instead. Useful for pagination.

Account list

}

Parameters for send block:

• wallet (optional): The wallet ID that the account account the block is being created for is in.
• key (optional): Instead of using "wallet" parameter, you can directly pass in a private key.
• account: The account the block is being created for (xrb_youraccount)
• destination: The account that the sent funds should be accessible to
• balance: The current balance of the account that the send is originating from, formatted in 'raw' units using a decimal integer.
• amount: The amount being sent (must be less than or equal to balance), formatted in 'raw' units using a decimal integer.
• previous: The block hash of the previous block on this account's block chain.

Warning: It is critical that balance is the balance of the account at the previous block. If this is not the case, then the amount sent will be different than the amount parameter. This is because send blocks contain the balance after the send, so nano_node uses balance - amount. If balance is 1 Nano less than it should be, then 1 Nano more will be sent than should be.

}

Proof of Work is precomputed for one transaction in the background. If it has been a while since your last transaction it will send instantly, the next one will need to wait for Proof of Work to be generated.

If the request times out, then the send may or may not have gone through. Most exchange "double withdraw" bugs are caused because a request was incorrectly retried. If you want to the ability to retry a failed send, all send calls must specify the id parameter as follows

Highly recommended "id"

version 10.0+

You can (and should) specify a unique id for each spend to provide idempotency. That means that if you call send two times with the same id, the second request won't send any additional Nano, and will return the first block instead. The id can be any string. This may be a required parameter in the future.

If you accidentally reuse an id, the send will not go through (it will be seen as a duplicate request), so make sure your ids are unique! They must be unique per node, and are not segregated per wallet.

Using the same id for requests with different parameters (wallet, source, destination, and amount) is undefined behavior and may result in an error in the future.

Request:

{  
  "action": "send",  
  "wallet": "000D1BAEC8EC208142C99059B393051BAC8380F9B5A2E6B2489A277D81789F3F",

}

Sending the request again will yield the same block, and will not affect the ledger.

In the future, the response may also indicate if the block is new. However, that has not yet been implemented.
