Step‑by‑Step Guide to Adding Crypto Payments with Cregis API

First, create a wallet on the Cregis platform, which acts as a Web3‑style aggregated payment service. The platform automatically adds a wide range of supported cryptocurrencies, and you can optionally select specific coins. Wallets can be single‑signature or multi‑signature.

1. Wallet Creation

Use the Cregis API to generate a new wallet. After creation, the system populates many mainstream token contracts, providing ready‑to‑use addresses for each supported coin.

2. Managing Payment Addresses

Each wallet can hold multiple addresses. Addresses are created via the backend UI or programmatically through the API. These addresses serve as virtual accounts for individual orders or customers, similar to a bank’s transaction‑identification product.

In the address book, you can assign addresses for inbound payments only, outbound payments only, or both, simplifying reconciliation.

3. Configuring the Payment Engine

The payment engine setup mirrors traditional WeChat/Alipay flows: create a merchant, then configure API credentials. Specify the merchant name and brand that appear on the checkout page.

Select the payment currency and the blockchain network; the UI indicates the minimum payable amount for the chosen chain.

Set the settlement currency separately for each payment currency.

Before invoking any API, add the caller’s IP address to the whitelist; otherwise the API will reject the request.

4. Launching the Checkout

Call Cregis’s order‑creation endpoint to obtain a standard checkout URL. The checkout lets users choose a cryptocurrency, select the network, and pick a wallet for payment. After a successful payment, the user is redirected to the success_url you provide, which typically returns to the merchant site after a short delay.

5. Funds Consolidation

Collected payments are scattered across many addresses. Cregis offers an automatic fund‑aggregation feature that moves balances into a designated master wallet. This can also be triggered manually via API.

6. Transaction Query

Use the platform’s query APIs to retrieve payment amounts, transaction details, and reconciliation data, enabling daily accounting and audit.

Overall, the guide demonstrates that integrating a crypto payment method can be as straightforward as traditional digital payments, with the added steps of selecting a coin and network.
