Email Parser Dropbox Integration for Attachment Governance

Use this email parser Dropbox integration guide when your team receives operational files by email and needs deterministic storage, retrieval, and auditability.

Quick answer: What should be standardized?

Standardize three layers:

1. document identity (external_key, sender, document class).
2. storage policy (folder path, naming convention, retention class).
3. evidence trail (trace_id, parse version, upload result).

Folder policy map

Parsed field	Dropbox rule	Validation
document_class	top-level folder selection	allowlisted classes only
customer_id	subfolder key	required for customer-scoped docs
statement_period	filename suffix	normalized YYYY-MM format
attachment_hash	duplicate detection	do not store duplicate hash in same lane
retention_tier	lifecycle label	must map to policy table

Implementation sequence

1. ingest inbound message and attachment metadata in MailSlurp.
2. parse fields into a strict file-ingestion schema.
3. compute deterministic path and filename rules.
4. upload attachment and metadata pointer to Dropbox.
5. persist parse + upload audit event for replay.

Failure policy

• missing policy fields: hold for review, skip upload.
• duplicate hash in same retention lane: treat as no-op or revision based on policy.
• Dropbox write failure: retry with backoff using same external key.
