This page walks through one member's full session to show how the transfer wallet integration works. Before you start, complete [Before you start](https://doc.va777.net/en/v2.md#before-you-start) on the overview page to get the API domain `{host}`, the token and the API key. ## Flow ```mermaid theme={null} sequenceDiagram participant M as Member participant S as Your server participant V as VA API S->>V: 1.

Before the member plays, you transfer balance in from your own wallet (deposit). When the member leaves, you transfer it back (withdraw). ## About the examples * Every example computes `sign` with the API key `a188va`. Use the API key we give you, and follow [Signature](https://doc.va777.net/en/v2/guides/signature.md). * `POST` requests are sent as `multipart/form-data` (curl `-F`). `GET` requests are sent as a query string (curl `-G --data-urlencode`). * Check `status.code` in every response. `0` means success; see [Response codes](https://doc.va777.net/en/v2/reference/response-codes.md) for the rest. ## 1. Create a member Before a member plays for the first time, call [Create member](https://doc.va777.net/en/v2/api-reference/member/create.md). The same account in different channels is treated as different members, and accounts are case-sensitive. ```bash theme={null} curl -X POST "{host}/vendor/v2.0/member/create" \ -H "Authorization: {token}" \ -F channelID=1 \ -F account=player001 \ -F currency=CNY \ -F sign=999d2836a05da3baa7f951d12954c23a ``` If the account already exists, the response code is `202` and you can keep using that account. ## 2. Deposit Call [Deposit](https://doc.va777.net/en/v2/api-reference/transaction/deposit.md) to move balance into the member's wallet. `transactionID` must be unique and start with `deposit-`. ```bash theme={null} curl -X POST "{host}/vendor/v2.0/transaction/deposit" \ -H "Authorization: {token}" \ -F transactionID=deposit-20250101000001 \ -F channelID=1 \ -F account=player001 \ -F currency=CNY \ -F amount=10.00 \ -F sign=4899d19dd28e49b04e1656afb1f7dc4f ``` The response `data` includes the balance before and after, `balanceBefore` and `balanceAfter`. Keep the `transactionID` and the response so you can reconcile later with [Get transaction detail](https://doc.va777.net/en/v2/api-reference/transaction/detail.md). ## 3. Get a game link Call [Get game link](https://doc.va777.net/en/v2/api-reference/game/link.md) and redirect the member to the `url` in the response. Set `gameID` to `0` to open the game lobby; to open a specific game, look up its ID with [Get game list](https://doc.va777.net/en/v2/api-reference/game/list.md). ```bash theme={null} curl -G "{host}/vendor/v2.0/game/link" \ -H "Authorization: {token}" \ --data-urlencode channelID=1 \ --data-urlencode account=player001 \ --data-urlencode currency=CNY \ --data-urlencode gameID=0 \ --data-urlencode gamePlat=web \ --data-urlencode app=N \ --data-urlencode lang=en-US \ --data-urlencode clientIP=203.0.113.10 \ --data-urlencode sign=72f94e26ece298e78d08b4ffedf99f63 ``` A game link is valid for 300 seconds, so redirect the member right away. `clientIP` is the member's IP and is not signed. See [Languages](https://doc.va777.net/en/v2/reference/languages.md) for supported language codes. ## 4. Fetch bet records While members play, call [List bet records](https://doc.va777.net/en/v2/api-reference/betlog/list-by-time.md) periodically. On the first query, send `nextToken` as an empty string; the empty value is still included in the signature. ```bash theme={null} curl -G "{host}/vendor/v2.0/betlog/listByTime" \ -H "Authorization: {token}" \ --data-urlencode channelID=1 \ --data-urlencode startTime=2025-12-01T00:00:00.000+08:00 \ --data-urlencode endTime=2025-12-01T00:01:00.000+08:00 \ --data-urlencode nextToken= \ --data-urlencode maxResults=5000 \ --data-urlencode sign=d1afe83cb4e05a496cc2311cc0cbc2f6 ``` When there is more than one page, pass the `nextToken` from the previous response as described in [Pagination](https://doc.va777.net/en/v2/guides/pagination.md). For continuous fetching, make each query's start time equal to the previous query's end time so no bets are missed. ## 5. Withdraw When the member finishes, call [Withdraw](https://doc.va777.net/en/v2/api-reference/transaction/withdraw.md) to move the balance back to your wallet. `transactionID` must be unique and start with `withdraw-`. You can check the amount first with [Get member balance](https://doc.va777.net/en/v2/api-reference/member/balance.md). ```bash theme={null} curl -X POST "{host}/vendor/v2.0/transaction/withdraw" \ -H "Authorization: {token}" \ -F transactionID=withdraw-20250101000001 \ -F channelID=1 \ -F account=player001 \ -F currency=CNY \ -F amount=10.00 \ -F sign=67628704041cb512f64c16540262d788 ``` ## Reconciliation | Purpose | API | | - | - | | Transaction records | [List transactions](https://doc.va777.net/en/v2/api-reference/transaction/list.md), [Get transaction detail](https://doc.va777.net/en/v2/api-reference/transaction/detail.md) | | Balance changes | [List balance changes](https://doc.va777.net/en/v2/api-reference/transaction/change-list.md) | | Win/loss summaries | [Get currency report](https://doc.va777.net/en/v2/api-reference/report/currency.md), [Get member report](https://doc.va777.net/en/v2/api-reference/report/member.md) | This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
