asyncapi_published: false
description: >-
  G2 publishes no AsyncAPI document and no event catalog. It does operate one real outbound
  webhook surface — G2 lead delivery — configured per customer in my.G2 and documented only
  through two destination-specific integration guides.
webhooks:
  - name: G2 lead webhook
    direction: outbound
    trigger: >-
      A buyer submits the lead form on the customer's G2 product profile page (including via
      Contact and other CTAs).
    delivery: HTTP POST to a customer-configured endpoint
    configuration: my.G2 — lead form setup, then webhook setup
    docs: https://documentation.g2.com/docs/leads
    destinations_documented:
      - name: HubSpot
        docs: https://documentation.g2.com/docs/hubspot-webhook
        mechanism: >-
          Delivered into a HubSpot embedded form; G2 lead fields are mapped one by one onto
          HubSpot form fields.
      - name: Salesforce CRM
        docs: https://documentation.g2.com/docs/salesforce-crm-webhook
    payload:
      schema_published: false
      note: >-
        No payload schema, no field list with types, and no example body are published. The
        docs describe field mapping as a manual, per-customer exercise ("dozens of fields that
        need to be matched"), because the field set is determined by the customer's own lead
        form.
      standard_fields:
        note: >-
          The lead form's standard fields are enumerated in the Leads documentation (including
          Phone Number, Message, and Company/Company Size/Industry which G2 may auto-populate
          from IP-based firmographic matching rather than from buyer input). Field API names
          are auto-generated from the label when a custom field is added.
      custom_fields:
        supported: true
        types: [Text Field, Menu, Hidden]
        note: >-
          Hidden fields are the documented mechanism for carrying customer tracking values
          through to the receiving system.
    security:
      signing: not documented
      retries: not documented
      note: >-
        No signature header, secret, replay protection or retry/backoff policy is published.
        A receiver cannot verify that a delivery came from G2.
    reliability: not documented
gaps:
  - No AsyncAPI or event-catalog document.
  - No webhook payload schema or example body.
  - No delivery signing or verification mechanism documented.
  - No subscription API — webhooks are configured through the my.G2 UI only, with no endpoint in the OpenAPI to register or list them.
  - No event types beyond lead delivery (no review-published, badge-awarded or intent-signal events).
polling_alternative:
  note: >-
    In the absence of events, incremental change is retrieved by polling with
    filter[updated_at_gt] / filter[created_at_gt], available on 14 and 13 operations
    respectively. See conventions/g2-conventions.yml.
