npm install coinpayments
Setup
- Create an account on www.coinpayments.net
- Go to My Account -> Coin Acceptance Settings
- Check the coins you wish to accept.
- You can setup your payment address, so you can use coinpayments as a pass thru service, rather then a cloud wallet (Payout mode ASAP/Nightly).
- Payout Made (To Balance/ASAP/Nightly)
- To Balance: Received payments are stored in your account for later withdrawal at your leisure.
- ASAP: Received payments are sent to the address you specify as soon as they are received and confirmed.
- Nightly: Received payments are grouped together and sent daily (at approx. midnight EST GMT -0500). The main benefit of this options is it will save you coin TX fees
- Discount (%)
- Positive Numbers: Gives buyers a discount for paying with a coin. Good promotional tool if you want to give extra support to a particular coin.
- Negative Numbers: Adds a certain percentage for paying with a coin. This could be used to cover your crypto/fiat conversation costs, make adjustments to match your local exchange, etc.
- Go to My Account -> API Keys , generate API key pair
- Edit permissions on the generated API KEY and enable all options
- Get some Litecoin testnet coins here

Local development
Payment notifications are not available for local development. However, there is a feature which is outside of scope of this module.
Most Coinpayment buttons (Frontend form submissions) have a bunch of handy parameters. Most handy would be: success_url
, cancel_url
.
Like most eCommerce systems, there are usually two endpoints, one for callback URL ( client triggered ) and POST notifications ( payment processor confirmations ). Preferably on local development, using forms requests should be enought, however staging/production environments should include notifications.
Instant payment notifications
This is a separate npm package. coinpayments-ipn
