Send and receive transactions in bitcoin

How to send and receive a transaction using a bitcoin address.
I use this URL .
I only have bitcoin addresses to send and receive.
Also, I don’t have a My Wallet account.

I used below code.

$to = // Bitcoin address1 $from = // Bitcoin address2 $json_url = "https://blockchain.info/merchant/d15dea6639d24b81e5caefad8aa4b0c6831cdccf1c21f8c234fd568d40e4238d/payment?to=$to&amount=5000&from=$from";


I got the error below.

 "You must provide a recipient address"

Thanks to everyone.

Just fill out the information below ... You need an account at BlockChain to send payments. You do not need an account to receive, however. It is just a send, not a callback. If you are looking for a callback, read on in the documentation further.

https://blockchain.info/merchant/ $ Help / payment password = $ main_password & amp ;? Second_password = $ second_password & amp; k = $ address & amp; amount = $ amount & amp; from = $ from & amp; common = $ common and amplifier board = $ fee¬e = $ note

 <?php $guid="GUID_HERE"; $firstpassword="PASSWORD_HERE"; $secondpassword="PASSWORD_HERE"; $amounta = "10000000"; $amountb = "400000"; $addressa = "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq"; $addressb = "1ExD2je6UNxL5oSu6iPUhn9Ta7UrN8bjBy"; $recipients = urlencode(json_encode( array( $addressa => $amounta, $addressb => $amountb ) )); $json_url = "https://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients"; $json_data = file_get_contents($json_url); $json_feed = json_decode($json_data); $message = $json_feed->message; $txid = $json_feed->tx_hash; ?>

You need a wallet on blockchain.info to send / receive funds using the "My Wallet API": https://blockchain.info/api/blockchain_wallet_api

If you are going to use this API, I have a PHP class that I use to interact with my blockchain wallet: https://github.com/lukesims/Blockchain-API-PHP-Class You may find this useful.

If you just want to receive payments, use the "Payee API", which is different. I can't post more than two links, but the blockchain section of the blockchain makes a pretty obvious difference between the two.
