Explore the SendBit API

An incredibly easy method for websites to receive bitcoin payments. This service is completely free and secure and is perfect for business or personal use.

The Sendbit API is the quickest and easiest way to begin accepting automated crypto payments. Consisting of just a simple HTTP Post request, you can be up and running in minutes.

To use the Receive Payments API, please generate an API key using your dashboard. You should always keep your secret key safe and it should not be enclosed at any point or this could result in loss of funds.

Call-backs are sent every one minute to your call-back address until you receive three confirmations on the transaction.

All API calls are implemented as a HTTP Post. Requests must be made to our API endpoint located at https://sendbit.io/api/[METHOD]

Sensitive data that would normally reside on our servers is disconnected entirely from the Internet. Wallets and private keys are stored using AES-256 encryption.


Our system generates a new address each time you wish to receive payments. This makes it difficult for anyone to trace your previous transactions on the blockchain.

Low fees

There are no hidden fees - we charge a flat fee of 0.3%, this is called a network fee. We allow users to decide their own miners fee; never pay high miner fees again with Sendbit.
