Connect Cybersource to Hypamoon

Yes, with one catch. Cybersource has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.

Open

The check

Three questions about the API of Cybersource, answered from its own docs.

Public API docs
Yes. Read the docs
A key you create yourself
Yes. In the Business Center under Payment Configuration > Key Management, generate a REST certificate key. developer.cybersource.com
Versions or a changelog
Yes. Release notes for the official SDKs list the API changes per release. github.com
How it signs in
A JSON Web Token signed with the private key from a P12 certificate you generate in the Business Center; HTTP signature with a shared secret is being phased out.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
Production access comes with a Cybersource merchant account, usually through your acquirer or Visa.

Your own payments overview on Cybersource, for support and finance.

  • Payments, captures, refunds and reports, from the Cybersource REST API.
  • AI that groups declines by reason each morning, with you deciding what to follow up.
  • A screen for support and a daily email for finance.

Ask your chat

Answers straight from your Cybersource data, in Claude or another chat with the full Hypamoon connection.

  • Which payments for this order reference were declined, and why?
  • Which authorisations from last week were never captured?

On a schedule

Cybersource has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next.

  1. Every 15 minutes

    Every morning, the declines of the previous day.

    AI decides

    AI groups them by reason and spots unusual patterns.

    Then

    Your team gets one email with the summary.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Cybersource data.

  • For your team

    Support looks up a payment by order number and sees whether it was captured or refunded.

Cybersource stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Cybersource waits for your approval, one call at a time. How adapters work

Good to know

  • Cybersource signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Cybersource takes more work: ask your chat to check this first.
  • The P12 certificate expires after 1 to 36 months (12 by default), so plan a new key in time.
