spec_type: Webhooks
summary: >-
  The GUARD underwriting API is asynchronous and delivers its result to a
  partner-hosted callback (webhook) endpoint. alt.bank does not publish an
  AsyncAPI document; this captures the documented webhook/callback surface.
transport: https
delivery: >-
  Partner registers a callback URL with alt.bank before using the API. When an
  underwriting request finishes, alt.bank POSTs the result to that URL.
events:
- name: underwriting.completed
  direction: alt.bank -> partner callback URL
  trigger: >-
    A credit-card underwriting request submitted to
    POST /api/partner/credit/cards/underwritings has finished processing.
  method: POST
  target: partner-registered callback URL
  payload_fields:
  - finished_datetime
  - score
  - risk_band
  - credit_limit
  note: >-
    Field list is derived from the documented underwriting response
    (finished datetime, score, risk band, credit-limit decision). Exact JSON
    property names are behind the portal's private OpenAPI document.
