Hi guys. I am using Blockchain.info's API to send multiple payments. I believe I have everything how it should be however when I run the code I get the following Error: RuntimeError: ERROR: Invalid Recipients JSON. Please make sure it is url encoded and consult the docs. The docs can be found here:
https://blockchain.info/api/blockchain_wallet_apiThe Python library I am using can be found here:
https://github.com/p4u/blockchain.py/blob/master/blockchain.pyThe only other post on this issue is posted by the original creator of the library, he said the problem was that the amounts cannot be a decimal, mine are not however.Post can be found here:
