Returns a single bank account by ID. The number field contains the full account number — use this endpoint when you need the complete value for payment processing or verification. For reconciliation use cases where only the last four digits are sufficient, prefer GET /v2/bank-accounts which returns all accounts with numbers masked to ****<last4>.

Returns 404 if the bank account does not exist or is not visible to the authenticated customer. A 403 is returned only when the caller’s token lacks the required scope; cross-customer access returns 404, not 403.

Permanently deletes a bank account. Returns 404 if the bank account does not exist or is not accessible to the caller.

Updates an existing bank account scoped to the authenticated customer. Returns the updated record with the account number masked.

Returns every bank account (person-owned or firm-owned) visible to the authenticated customer, paginated by opaque continuation token. Use this endpoint to reconcile bank accounts across all producers in a customer’s account without iterating known producer IDs. Account numbers are masked to ****; the unmasked value is reachable only via GET /v2/bank-accounts/{id} behind an elevated scope.
