TypeScript SDK — Account Services: Banking & Payments

Link bank accounts and manage payment methods. All methods are on client.account.

See the API specifications for full request/response schemas and the authentication guide for setup.

Methods

addBank

POST /v1/payments/addbank · Authenticated

Links a US bank account for fiat deposits and withdrawals. The request body is validated client-side. The SDK enforces:

• accountnumber — required string
• routing — required string
• name — required string (account holder name)
• type — required enum: "checking" or "savings"

Code
const result = await client.account.addBank({
  accountnumber: "123456789",
  routing: "021000021",
  name: "Jane Doe",
  type: "checking",
});

This is a POST mutation — never automatically retried. Double-check account details before submitting; linking an incorrect account requires manual correction.

addBankCAD

POST /v1/payments/addbank/cad · Authenticated

Links a Canadian bank account for CAD deposits and withdrawals. The request body is validated client-side. The SDK enforces:

• swiftcode — required string
• accountNumber — required string
• name — required string
• type — required enum: "checking" or "savings"
• institutionNumber, branchnnumber — optional strings

Code
const result = await client.account.addBankCAD({
  swiftcode: "ROYCCAT2",
  accountNumber: "1234567",
  name: "Jane Doe",
  type: "checking",
  institutionNumber: "003",
  branchnnumber: "00012",
});

Note: The field name branchnnumber (with double "n") matches the API specification exactly.

listPaymentMethods

POST /v1/payments/methods · Authenticated

Returns all payment methods linked to the account. The response is a wrapper object with balances and banks arrays — not a bare array.

Code
const methods = await client.account.listPaymentMethods({});

// Fiat balances available for trading
for (const balance of methods.balances ?? []) {
  console.log(`${balance.currency}: ${balance.available} available`);
}

// Linked bank accounts
for (const bank of methods.banks ?? []) {
  console.log(`${bank.bank} (${bank.bankId})`);
}

This is a POST mutation — never automatically retried.
