Provider API

The Provider API defines the REST contract that every provider must implement. The Document Service Broker calls these endpoints to fetch documents and manage annotations on behalf of the viewer.

For the broker-side endpoints that consume this API, see Broker API - Provider operations.

Data model

The Provider API uses a polymorphic document model for composite document support. The rest-provider-api library provides the shared Java types.

ProviderDocument

Abstract base type for all document types. Uses a type property as a discriminator.

Field	Type	Description
`name`	`String`	Display name of the document or folder
`type`	`String`	Discriminator: `"file"` or `"folder"`

ProviderFile

Represents a single document.

Field	Type	Description
`name`	`String`	Document display name
`parameters`	`Map<String, String>`	Query parameters needed to fetch this document via `GET /documents`

{
  "type": "file",
  "name": "report.pdf",
  "parameters": {
    "id": "DOC123",
    "objectStoreName": "OS1"
  }
}

ProviderFolder

Represents a folder containing files and/or subfolders.

Field	Type	Description
`name`	`String`	Folder display name
`parameters`	`Map<String, String>`	Optional parameters for this folder
`contents`	`List<ProviderDocument>`	Child files and folders

{
  "type": "folder",
  "name": "Case Documents",
  "parameters": {},
  "contents": [
    {
      "type": "file",
      "name": "contract.pdf",
      "parameters": {
        "id": "DOC001",
        "objectStoreName": "OS1"
      }
    },
    {
      "type": "folder",
      "name": "Attachments",
      "parameters": {},
      "contents": [
        {
          "type": "file",
          "name": "annex.pdf",
          "parameters": {
            "id": "DOC002",
            "objectStoreName": "OS1"
          }
        }
      ]
    }
  ]
}

Endpoints

Retrieve a document

GET /documents

Fetches document content. Returns either a binary stream for a single document, or a JSON ProviderFolder for a composite document.

Parameters

Name	In	Type	Required	Description
`objectStoreName`	query	string	provider-specific	FileNet. The object store name.
`id`	query	string	provider-specific	FileNet. The document identifier.
`vsId`	query	string	provider-specific	FileNet. The version series identifier.
`objectType`	query	string	provider-specific	FileNet. The object type.
`contentElement`	query	string	provider-specific	FileNet. The content element index.
`nodeRef`	query	string	provider-specific	Alfresco. The node reference.
`alf_ticket`	query	string	provider-specific	Alfresco. The authentication ticket.
`user`	query	string	provider-specific	Alfresco. The user identifier.
`versionLabel`	query	string	provider-specific	Alfresco. The version label.

Query parameters are provider-specific. These are the whitelisted parameters forwarded by the broker from the original request.

Response

Single document -- The response body is a binary content stream.

Header	Value	Description
`Content-Type`	`application/octet-stream` or specific MIME type	Document MIME type
`Content-Disposition`	`attachment; filename*=UTF-8''<encoded-name>`	Optional. Document title displayed in ARender

Composite document -- The response body is a JSON ProviderFolder object. Each ProviderFile in the folder must include parameters with the values needed to fetch that file individually when the broker calls GET /documents again for each child.

Header	Value
`Content-Type`	`application/json`

Errors

Status	Description
`403`	Access denied. The authenticated user does not have permission to view this document.
`404`	Document not found. No document matches the provided parameters.

Example request

Single document:

curl -X GET "http://filenet-provider:8787/documents?objectStoreName=OS1&id=DOC123"

Composite document:

curl -X GET "http://filenet-provider:8787/documents?objectStoreName=OS1&id=FOLDER001"

Example response

Single document returns a binary stream with appropriate headers. Composite document returns JSON:

{
  "type": "folder",
  "name": "My Folder",
  "parameters": {},
  "contents": [
    {
      "type": "file",
      "name": "file1.pdf",

    },
    {
      "type": "file",
