retrieve all the transaction between two addresses

Question

I've used this query to try to get all the transaction between two addresses:

https://blockchain.info/multiaddr?active=1EipJdYVJbqsTSQhj1icK424AkMbyjvgBm|1LWwLvKWbcpiZYqCcwfuQ3gjjNJkxftmEJ

but the thing is- according to my wallet there are many more transactions that aren't appearing in the json result here.

Why is that?

How can I see actually all of the transactions?

I though maybe blockexplorer would be better than blockchain.info, but actually- not so.

They have it as this:

https://blockexplorer.com/api/addrs/1EipJdYVJbqsTSQhj1icK424AkMbyjvgBm,1LWwLvKWbcpiZYqCcwfuQ3gjjNJkxftmEJ/txs?from=0&to=50

perhaps it would be better to just query by txid?

Answer 1

I don't believe you can do this with just a single API call. I'd return all the transactions from one of the addresses, and cycle through all the inputs and outputs and if they match the other address then show the tx data.

Not sure which language you're using but the logic should be the same.

<?php
$addr1 = "1EipJdYVJbqsTSQhj1icK424AkMbyjvgBm";
$addr2 = "1LWwLvKWbcpiZYqCcwfuQ3gjjNJkxftmEJ";

$url = "https://blockchain.info/address/".$addr1."?format=json";
$fgc = json_decode(file_get_contents($url), true);

//num of txs
$txs = count($fgc["txs"]);

//loop through all txs
for($i=0;$i<$txs;$i++){
    //check all inputs & outputs for the other address
    //inputs
    $numinputs = count($fgc["txs"][$i]["inputs"]);
    for($ii=0;$ii<$numinputs;$ii++){
        if($fgc["txs"][$i]["inputs"][$ii]["prev_out"]["addr"] == $addr2){
            //found a corresponding tx
            print_r($fgc["txs"][$i]);
        }
    }//end inputs loop

    $numoutputs = count($fgc["txs"][$i]["out"]);
    for($iii=0;$iii<$numoutputs;$iii++){
        if($fgc["txs"][$i]["out"][$iii]["addr"] == $addr2){
            //found a corresponding tx
            print_r($fgc["txs"][$i]);
        }
    }//end outputs loop
}

?>

I had trouble too. Documentation is unclear. This link works by way of browser: https://blockchain.info/multiaddr?address=641ad5051edd97029a003fe9efb29359fcee409d&address=1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq
