Data Classification & Storage

Antei classifies all incoming data across integrations, uploads, and APIs into structured categories. This enables consistent handling, secure storage, and proper routing across internal services.

​
Data Classification Model

Each field in the platform is tagged with metadata to guide its treatment across ingestion, mapping, validation, and downstream usage.

ClassificationDescription
Core IdentifierFields required to uniquely identify entities (e.g. contact_id, txn_id)
JurisdictionalFields that impact region-specific logic (e.g. country, state, tax_id)
FinancialMonetary fields like amount, tax, currency, exchange_rate
DerivedComputed or post-processed fields (e.g. reverse_charge_applied)
SensitivePersonally identifiable or regulatory-sensitive (e.g. email, ip_address)
Audit MetadataSync metadata such as source, sync_time, extracted_id, mapping_tag

Each record (invoice, transaction, product, contact) is processed using these classifications.

​
Storage Architecture

Antei uses a layered storage model based on data sensitivity and processing stage:

LayerDescription
Ingestion LayerTemporary staging of raw integration payloads (used during transformation)
Validation LayerIntermediate storage for normalized and enriched records
Primary DatabaseSystem-of-record for validated data, powered by Xano
Document StoreFile storage (e.g. invoices, registrations) managed via Cloudflare R2
Logs & MetadataProcess logs and metadata maintained through Railway and Render

📌 Sensitive documents (e.g. tax notices) are never stored in plaintext. Access is scoped and logged.

​
Encryption & Access Control

  • At Rest: Data is encrypted using native encryption mechanisms (Xano, R2)
  • In Transit: All communication uses HTTPS (TLS 1.2+)
  • Scoped Access: Token-based access to file URLs with expiration
  • Field-Level Protection: Sensitive fields like emails and tax IDs are excluded from logs by default

​
Field Metadata Example

Every mapped field carries classification and sync metadata. For example:

{
  "field": "invoice_total_amount",
  "source": "stripe_invoice.total",
  "extracted_id": "abc123",
  "isSensitive": false,
  "classification": "financial",
  "mappingVersion": "v1.3"
}
