JPM Merchant API Integrations

Guide a merchant through integrating one of the supported J.P. Morgan Payments APIs. Authentication is assumed to be in place — if it isn't, point the user at jpm-integrations-get-started (which hands off to jpm-oauth) and exit. For inbound webhooks, hand off to jpm-notifications.

Step 1 — Confirm prerequisites

The merchant should already have:

• Validated credentials (clientId, cert path, private key path, SHA-1 thumbprint, resource_id)
• An auth module in their project that exposes a getAccessToken() function (or its language equivalent)

If you arrived here from jpm-oauth, both are already known — the auth module's path is in conversation context. Use it directly.

If invoked standalone, ask:

• Question: "Is JPM authentication already wired up in this project?"
• Header: "Auth ready?"
• Options:
  • "Yes — I already have a working getAccessToken() (or equivalent)"
  • "No — I haven't set up auth yet"
