note: >-
  Centene publishes NO AsyncAPI document and no event-subscription surface for third-party
  developers - there is nothing to subscribe to, no event catalogue, and no outbound callback a
  developer can register for. What it does publish, and what is captured here, is the inverse:
  three catalogue entries Centene itself labels "Webhook", which are INBOUND receiver endpoints a
  named partner (Sinch, the SMS provider) posts into. Recording the direction matters - an
  integrator reading "webhook" on this portal will not get callbacks from Centene.

    content_types: [application/json, text/json, application/x-www-form-urlencoded]
    payload_schema: >-
      Untyped. The spec declares the body as a bare `{"type": "object"}` with no properties, so
      the event shape is not published.
    spec: openapi/centene-ccm-sms-userresponse-openapi.json
    purpose: >-
      Receives a member's SMS reply from Sinch and places it on the CCM (care/campaign management)
      queue.

    note: >-
      Host api-gateway-01.centene.com does not resolve from the public internet. Spelled "Synch"
      in three catalogue entries and "Sinch" in two, for the same vendor.

    catalogue_entries:
      - REST Admin API
      - External Kafka API - Test
      - External Kafka API - Dev
    contract: >-
      Confluent's Kafka REST Admin API v3 OpenAPI, republished verbatim (info.contact is
      kafka-clients-proxy-team@confluent.io and servers[] are templated
      {protocol}://{address}:{port}/v3). Centene points it at its own KaaS clusters -
      bootstrap.xkaf.dev.kaas.aws.centene.com, bootstrap.xkaf.tst.kaas.aws.centene.com,
      bootstrap.xka2.tst.kaas.aws.centene.com.
    note: >-
      Deliberately NOT saved to openapi/ as a Centene contract. It is Confluent's document, and
      all three registered clusters are dev/test hostnames that do not resolve publicly. Recorded
      here because it is the only event-streaming surface Centene lists, and because an
      integrator should know it exists and that it is not reachable.
gaps:
  - No AsyncAPI document for any surface.
  - >-
    No outbound webhooks for third-party developers. A CMS Patient Access app has no way to be
    notified that a member's claims or coverage changed; it must poll.
  - >-
    Every inbound webhook payload is declared as an untyped object, so even the named partner
    integrations have no published event schema.
