Wire Transfer

Send urgent and high-value payments with control and traceability

Enable partner applications to initiate wire transfers through KeyBank’s Wire Transfer API. This API helps organizations send urgent or high-value payments, validate payment details before initiation, support domestic and international payment scenarios, and maintain payment traceability through structured reference information.

Features

Wire payment initiation

• Initiate wire transfers using the Wire service capability.
• Support urgent, high-value, or large-volume payment workflows.
• Send payments to individuals, corporations, beneficiaries, or financial institutions in the payment chain.

Payment validation

• Validate wire payment details before creating a payment.
• Use validation checks to identify missing or invalid data before initiation.
• Support safer payment workflows by confirming required party, address, transfer, and routing information.

Domestic and international payment support

• Support domestic wire scenarios using routing information such as ABA numbers.
• Support international wire scenarios using BIC and foreign bank system identifiers when required.
• Provide structured party and address information based on payment type and scenario.

Traceability and reconciliation

• Use request, sender, receiver, and originator reference IDs to support traceability.
• Help reduce manual work and payment identification errors.
• Include custom data that stays with the transaction through its lifecycle.

Duplicate payment prevention

• Use request reference values to support idempotency and safe retries.
• Support duplicate checks based on key payment fields.
• Help reduce duplicate payment risk for similar or repeated wire transfers.
