Package access

6MM provides the approved package coordinates and version during partner onboarding. Use the package source configured for your organization.

Before you start

• Confirm your production Agent API base URL with the 6MM team.
• Store apiSecret in backend secret management only.
• Prepare a stable mapping between platformUserId and agentUserId.
• Enable structured logs around bind, transfer, order, and webhook flows.

Initialize client

1
AgentClient client = new AgentClient(AgentClientConfig.builder()
2
        .baseUrl("https://api.6mm.com/agent")
3
        .agentCode("AGENT001")
4
        .apiSecret("your-api-secret")
5
        .defaultCurrency("USDT")
6
        .build());

Backend only

Do not initialize the Agent SDK from browser, mobile, or desktop client code. The SDK signs privileged Agent API requests.

Example: transfer funds in

1
TransferResponse resp = client.transfer(TransferRequest.fixed(
2
        "AGT-ORDER-1001",
3
        "agent-user-001",
4
        Direction.IN,
5
        "USDT",
6
        "10.00"));

Use a unique partner-side order number for each transfer request. If a request times out, query the original order before creating a new one.
