How to send bitcoins to multiple recipients at once

Question

Hi.. I have gone through blockchain API documentation and understood how to send bitcoins to a recipient but now I want to send bitcoins to two recipients at once. I am using the following code:

recipes ={'1Pd9gXJ8EqyGrqMKVevQWNjjF4B4dcSykf':10000,'14gVMjoCbjaGU3s9EQghVxYTAJgkmqqtHV':10000}

url_multi = 'https://blockchain.info/nl/merchant/MYKEY/sendmany?password=MYPASSWORD&recipients='+recipes+'&fee=15000'

requests.get(url_multi)

but it doesn’t work. How can I do it?

Error log:

TypeError: cannot concatenate 'str' and 'dict' objects

Answer 1

To send bitcoins to multiple recipients, you need to send the recipients address as JSON object.

To convert it to JSON object, use the following code:

x = json.dumps(recipes)

Next, you can use your request as usual but by using the JSON object, like this:

url_multi = 'https://blockchain.info/nl/merchant/MYKEY/sendmany?password=MYPASSWORD&recipients='+x+'&fee=15000'

requests.get(url_multi)
