Args: collection_name: Name of the collection (path parameter) body: Dropbox directory configuration with directory_path

Returns: { job_id, status: "pending" }

post/v2/collections/{collection_name}/index/dropbox/directory

Path parameters

collection_namestring required

Headers

authorizationstring nullable

Request body

custom_metadataobject nullable

Custom metadata to attach to all indexed chunks. Keys must be strings. Values: str, int, float, bool, or List[str].

directory_pathstring required

Path to a folder within the Dropbox account (e.g. '/Reports/2024'). All files within this folder and its subfolders are indexed recursively.

dropbox_access_tokenstring required

Dropbox access token with files.metadata.read and files.content.read scopes. Generate one from the Dropbox App Console (Settings tab -> Generated access token). Tokens are short-lived and scoped to the token owner's account, ideal for one-shot indexing jobs.

max_filesinteger nullable
overwrite_existingboolean

When true, files that already exist in the collection are re-indexed and replaced with zero downtime: the new version is built alongside the live one and atomically swapped in when complete, so the previous version keeps serving search results throughout the rebuild. The document keeps the same document_id across overwrites, and its status reads 'updating' in the document listing while the rebuild runs. Requires skip_existing=false. Setting both to true returns a 400 error.

parsing_scriptstring nullable

Relative path to a JS parsing script for JSON files (e.g. 'research/paper-parser'). When provided, .json files are processed through a sandboxed V8 isolate. Without this, .json files are indexed as raw text.

processing_type'advanced' | 'basic' required

Document processing type. 'advanced' uses agentic OCR with AI-enhanced extraction for complex layouts, tables, figures, charts, and documents containing images. 'basic' provides reliable OCR optimized for general document indexing and high-volume processing.

skip_existingboolean

When true, files already indexed in the collection are skipped and will not be re-indexed with incoming changes. When false, all incoming files are indexed regardless of whether they already exist.

mask_piiboolean

When true, detected PII (emails, phone numbers, SSNs, credit cards, names, and locations) is masked in the parsed content before it is embedded and stored — replaced with entity tags like <PERSON> and <EMAIL_ADDRESS>. For images (including images embedded in PDFs), PII text visible in the image is also pixel-redacted. Opt-in; defaults to false, which leaves content unchanged.

transcription_languagestring nullable

AWS Transcribe language code for the spoken audio (e.g. 'es-US', 'pt-BR'). Omit to auto-detect per file. Video and audio files only. Supported codes: https://docs.aws.amazon.com/transcribe/latest/dg/supported-languages.html
