API workflow

Create a deposit address for each customer reference

The API returns a generated address and QR-code URL for a supported asset and network. Your backend keeps the customer context and decides how each processed deposit updates its own account or order state.

01.

Request an address

Call the authenticated merchant endpoint with a supported network and asset, plus an optional label or address-specific webhook URL.

02.

Store the customer mapping

Associate the returned address with your internal customer or account ID. Your application remains the source of truth for that relationship.

03.

Process deposit events

Use signed webhook data to match the address and transaction, then update your own payment or account-funding state.

B2B payment acceptance

Reconcile repeat deposits from signed webhook events

Signed webhook payloads provide the deposit address context and transaction details your backend needs. Your merchant system remains the source of truth for customer balances, accounts and orders.

01.

Address context

Match the incoming event to the generated address and optional customer label stored by your backend.

02.

Transaction details

Use the signed payload details to identify the network, asset and transaction for reconciliation.

03.

Merchant-owned records

Apply each processed deposit to the balance, account or order records maintained by your own system.

Who is the deposit address API for?

It is designed for merchants and platforms that accept inbound crypto payments inside their own products. Your application keeps its customer and account records and decides how each processed deposit updates its ledger.

When should I use a deposit address instead of an invoice?

Use a reusable deposit address for repeat payments or account funding. Use an invoice when a single order needs a fixed amount, checkout state and expiration.

How are deposit events delivered?

CoinsSend sends signed webhook payloads to the address-specific callback URL when configured, or to the merchant callback URL. The payload includes address, network, asset, label and transaction details for backend reconciliation.
