note: >-
  Marketo ships client-side embeddable surfaces that are distinct from its REST
  API and from the SDKs in packages/. These are the pieces a developer drops onto
  a customer's own web page, and they are how most Marketo data actually gets
  created — a form embed and a tracking script, not an API call.
families:
  - family: Forms 2.0
    kind: embeddable form
    loader: null
    loader_note: >-
      Adobe does not publish the embed snippet in the developer docs. Its
      Javascript API page states that "the embed code is unique to your Marketo
      instance because it contains an account identifier" and that it must be
      copied from the Marketo user interface, so there is no canonical script URL
      to record. .loadForm() takes baseUrl + munchkinId explicitly, which is the
      documented evidence that the loader is per-subscription.
    namespaces:
      - name: MktoForms2
        role: Top-level public namespace — creates, loads and retrieves Form objects.
        methods:
          - signature: .loadForm(baseUrl, munchkinId, formId, callback)
            description: Loads a form descriptor from Marketo servers and creates a new Form object.
          - signature: .lightbox(form, opts)
            description: Renders a lightbox modal containing a Form object. Returns an object with .show() and .hide().
            options: [onSuccess, closeBtn]
          - signature: .newForm(formData, callback)
            description: Creates a Form object from a Form Descriptor object produced by the Forms V2 editor.
          - signature: .getForm(formId)
            description: Retrieves a previously created Form object by form Vid.
          - signature: .allForms()
            description: Returns an array of every Form object constructed on the page.
          - signature: .getPageFields()
            description: Returns URL and referrer data useful for tracking.
          - signature: .whenReady(callback)
            description: >-
              Fires once per form on the page when the form exists, has rendered,
              and has run its initial callbacks. Fires immediately for forms
              already ready.
      - name: Form
        role: An individual embedded form instance.
    identifier: form Vid (form version id)
    docs: https://experienceleague.adobe.com/en/docs/marketo-developer/marketo/javascriptapi/forms-api-reference
    authoring_api: >-
      The server-side counterpart is the Asset API form surface —
      browseForms2UsingGET, createLpFormsUsingPOST, updateFormsUsingPOST,
      addFieldToAFormUsingPOST and the form-field operations in
      openapi/marketo-asset-openapi-original.json.
  - family: Munchkin
    kind: web tracking script
    role: >-
      Lead tracking / anonymous-visitor identification. Sets the Marketo tracking
      cookie whose value is the `cookie` parameter accepted by
      associateLeadUsingPOST, which is how an anonymous web session is bound to a
      known person record.
    api_link:
      operation: associateLeadUsingPOST
      spec: openapi/marketo-lead-database-openapi-original.json
      error: Error 1012 "Invalid cookie value '%s'" when the cookie value is malformed.

      getLpFormByIdUsingGET, the landing-page, landing-page-content,
      landing-page-template and landing-page-redirect-rule operations in

  - family: Email Script / Velocity tokens
    kind: server-side templating
    role: >-
      Email scripting and token substitution inside Marketo-authored emails and

      webhook payload templates.
