- 1.You obtain new address from CoinsPaid API (for some currencies it may be address and tag) and store it somewhere on your side. After that you show this address to your customer in order to make a deposit.
- 2.Customer sends some funds to this address.
- 3.When transaction is sent by a customer - CoinsPaid sends a callback to your callback url with transaction details. It contains status, address, currency, amount and fees. If status is successful, you should deposit respective amount to customer balance on your side.
- 1.You request to send amount of money to address.
- 2.Your request is validated on our side. If signature is correct, address is valid and you have enough balance - CoinsPaid responds you with the transaction object.
- 3.You will receive a callback when transaction status is updated.
Please note that the final status and all calculations on your side shall be applied only after receiving a final callback from Cryptoprocessing's side, hence in case a connection disruption takes place and you do not see a transaction on your side, kindly wait for a final callback or check a transaction in the back-office.
Deposit with exchange flow
You don't want to touch or store cryptocurrency, but only use it as a payment method. Your customer deposits BTC, Coinspaid instantly converts it to EUR so that you would receive EUR on your CoinsPaid account.
- 1.You obtain new address from CoinsPaid API same as in deposit flow, but additionally pass another parameter "convert_to" in your request specifying resulting currency.
- 2.When new deposit is arriving, CoinsPaid converts all arriving funds to destination funds, and sends notifications as in regular deposit
Withdrawal with exchange flow
You wish to send Cryptocurrency from your Fiat currency balance. For example you want to send EUR amount but your customer receives money in BTC.
- 1.You do exactly same as in withdrawals, but you specify 2 currencies. One is a currency of your sending balance and Second is a cryptocurrency your Customer wishes to receive.
- 2.Your request is validated on our side. If signature is correct, address is valid and you have enough balance - CoinsPaid responds you with the transaction object.
- 3.You will receive a callback when transaction status is updated.
Invoices allow to conduct deposits with a fixed rate within a limited period of time disregarding the exchange rate fluctuations. In case it’s necessary to convert funds in fiat currency or convert it to another crypto currency this option will allow to visualize the exact amount of a sender’s currency required to receive the exact amount in a receiver’s currency. When a deposit is processed through this flow, a user is being redirected to the respective Invoice page via the preset link and just needs to follow instructions specified on it. It also allows to conduct refunds in case a user fails to manage to deposit within an established timeframe or discovers non-sufficient balance. All is required in that case is to follow the link with the respective instructions sent to an e-mail of a customer.

Receive cryptocurrency
Business logic for using cryptocurrency as a deposit method:
You are willing to let your customer fund his EUR balance on your platform or website. You will have to generate an address in the desired cryptocurrency and specify EUR as a "convert_to" currency. This will allow you to let your Customer pay if his favorite currency and fund his balance in EUR. At the same time you will see respective EUR amount in your CoinsPaid merchant account.
Hint: you don't have to generate new address for this customer anymore, address can be reused unlimited amount of times.
Example of the customer facing interface for Deposits.
- Make sure to use Bitcoin URI format bitcoin: in QR. Works the same way as "mailto:".
- We do recommend making this QR clickable as customers may have a wallet set up on their computer or mobile phone.
- We recommend specifying approximate current exchange rate.
