spec_type: null
summary: >-
  LendKey publishes NO AsyncAPI document and NO consumer-subscribable event surface.
  The only webhook interface in the four published specs is an INBOUND receiver:
  the E-Sign API exposes POST /webhooks/docusign so DocuSign Connect can notify
  LendKey of envelope events, plus a health check DocuSign Connect uses to verify
  reachability. Integrators cannot register a callback URL with LendKey and receive
  events; they must poll (getApplicationStatuses for envelope progress, POST
  /v1/application/status for loan/application status).

rating_note: >-
  No Webhooks or AsyncAPI pointer is wired in apis.yml. The webhooks_advertised and
  asyncapi_events checks are about a provider advertising events that consumers can
  subscribe to; LendKey advertises none. Recording the inbound receiver here rather
  than claiming an event surface it does not have.
