The catalog indicates only that an event name can be configured; it does not imply a delivery SLA for every event. Fields in callback `data` may also vary by event. The current catalog contains seven events: document recognition completed, document extraction completed, and human collaboration started, succeeded, failed, completed, or timed out. `collaboration_timeout` currently means only that the event is registered; actual delivery is not guaranteed. ## OpenAPI ````yaml en/api-reference/adp-api.yaml GET /open/agentic_doc_processor/{tenant_name}/v1/webhook/events openapi: 3.1.0 info: title: ADP API version: 1.0.0 description: >- Laiye ADP OpenAPI reference for document extraction, recognition, and conversion; extraction application management; webhooks; human collaboration; credit usage; workflow discovery, runs, exports, and file management. license: name: MIT identifier: MIT servers: - url: https://adp-global.laiye.com description: ADP global production endpoint security: [] tags: - name: Document extraction description: Extract structured fields from uploaded documents. - name: Document recognition description: Recognize text, layout blocks, and positions from uploaded documents. - name: Document conversion description: >- Convert PDFs, Office documents, OFD files, and images into page images or native spreadsheet structures. - name: Application management description: >- Create, update, delete, and query extraction applications and configurations. - name: Webhook description: List system events and manage event callbacks. - name: Account description: Query credit usage. - name: Workflow description: >- List business workflow templates, run workflow applications, and query run results. - name: Workflow files description: Upload and manage files used by workflow applications. - name: Human collaboration description: >- Configure review triggers, query collaboration tasks, and submit human corrections. paths: /open/agentic_doc_processor/{tenant_name}/v1/webhook/events: get: tags: - Webhook summary: List Webhook event catalog description: > Return the system event types currently registered for subscription.
