summary: >-
  Keap ships one client-side embeddable surface: a hosted payment web component
  (`<keap-payment-method>`) delivered as a JavaScript bundle from payments.keap.page.
  It is not optional — Keap states that "in order to use any of Keap's payment
  processors the API developer will be REQUIRED to use Keap's hosted Payment
  component", so the card-data path is deliberately kept out of the REST API and
  inside the component. It brokers Stripe, PayPal and Authorize.Net behind one tag.

            The distribution URL is UNPINNED — it carries no version segment and no
            content hash, and the served bundle exposes no version string. A consumer
            cannot tell which build they are loading, and neither can we; recorded as
            null after checking, not left unchecked. Bundle is 7,679 bytes,
            text/javascript, HTTP 200 on 2026-08-13.

            POST https://api.infusionsoft.com/crm/rest/v2/paymentMethodConfigs with
            {"contact_id": ...} to mint a session key.
          step_2: Load the bundle, then render <keap-payment-method data-key="SESSION_KEY">.
          session_ttl: 1 hour
          note: Session keys expire after one hour; repeat step 1 to mint a new one.
