asyncapi_note: >-
  Nexla publishes NO AsyncAPI document. Searched the docs host, the sitemap (1,220 URLs), both GitHub
  orgs and /asyncapi.yaml on every host — nothing. Nothing is fabricated here. What Nexla DOES publish is
  an event surface described two ways: OpenAPI 3.1 `webhooks` for inbound record ingestion, and a
  notification/alerting catalog for outbound platform events.
surfaces:
- kind: inbound-webhook
  direction: 'external system -> Nexla'
  description: >-
    Nexla's webhook CONNECTOR gives a data source an HTTPS ingestion URL. Callers POST records to it and
    Nexla treats each object as a record, auto-detecting schema. This is declared natively as an OpenAPI
    3.1 webhooks block, which is why the surface is machine-readable even without AsyncAPI.

  auth:
  - 'api_key query parameter (NexlaApiKeyQuery)'
  - 'Basic <api-key> Authorization header (NexlaApiKeyHeader)'
  operations:
  - operationId: send_one_record
    method: POST
    summary: Send one record to Webhook
    content_types: [application/json, application/xml]
    responses: [200, 403, 500]
    options:
    - name: include_headers
      default: false
      description: >-
        'Set this to `true` if you wish to send any custom headers to be included in the ingested records
        as part of the request. The platform will ignore standard headers like Authorization and
        Content-Type. Any custom headers will be added as a header_<header_name> attribute in the record.'
    - name: include_url_params
      default: false
      description: >-
        'Set this to `true` if you wish to send any custom query parameters to be included in the ingested
        records. The platform will ignore standard query parameters like api_key. Any custom query
        parameters will be added as a url_param_<param_name> attribute in the record.'
    - name: force_schema_detection
      description: Force Nexla to re-detect the record schema on this request.
  - operationId: send_many_records
    method: POST
    summary: Send many records to Webhook
    content_types: [application/json]
    responses: [200, 403, 500]
    description: 'Send an array of JSON objects. Nexla will treat each object as a unique record for the webhook.'
- kind: outbound-notification
  direction: 'Nexla -> subscriber'
  description: >-
    Nexla raises typed notifications against flow resources. They are read and managed over REST
    (21 operations under the Notifications tag) and routed by notification_settings and
    notification_channel_settings. The docs publish the event catalog but not per-event payload schemas
    or delivery-channel guarantees, so no schema is asserted here.

  - 'No delivery-channel list (email / Slack / outbound HTTP) is published on the notification-types page.'
  - 'No payload schema is published for any notification event.'
streaming:
  note: >-
    Nexla also runs CDC and streaming ingestion (Kafka, Confluent Kafka, Google Pub/Sub, JMS, Tibco
    credential types are all declared in the REST contract). Those are DATA-PLANE connectors Nexla
    consumes, not an event API Nexla publishes to its own consumers, so they are not modelled as an
    AsyncAPI channel here.
