Catalog schema

When you upload a catalog via the Dialog API, the JSON must match this schema. Dialog’s AI Assistant uses this structured data to understand your products and recommend accurately.

  • Understand product features, variants, and specifications.
  • Make intelligent product comparisons.
  • Provide contextual recommendations based on customer needs.
  • Answer detailed questions about your inventory.

The more complete and structured your catalog, the better the answers.

Paste this into your validator of choice (Ajv, jsonschema, Pydantic via model_json_schema, etc.) to validate your payloads before upload.
