Bitcoin Forum

Hi. Not sure if this is the right topic, but whatever :P

I am trying to make something where i need to send many microtransactions. (<10000 satoshi)

The thing is, when i send any sort of transaction using an APi, i can't send any others unless the previous one is confirmed.

I get this error: {"error":"Insufficient Funds Available: 0 Needed: 10010"}

Anyone knows a way how to send money, and be able to send more without waiting the first one to get confirmed?

P.S: I sent it with a good fee: 0.0001 BTC

If the API does not allow to use unconfirmed inputs to be used there is nothing you can do but switch do a different API or use bitcoin core directly. It might be risky to use unconfirmed inputs though.

Are you using blockcypher API ?

I am not receiving the payments.

When i try sending money from a wallet it sends it successfully, but i cant send another transaction unless the first one is confirmed. I want to be able to use the remaining money to send another transaction without waiting first one to confirm.

Yes, you want to spend unconfirmed inputs. You "receive" change the same way you receive payments from someone else. You can somewhat mitigate this if you have several inputs available, but that might make your transactions bigger (in byte) and thus more expensive (in fees) over time.

how about blockhain api V2?

Haven't tried it yet. But i guess i'll have to.
