Async: 202. `jobId` is an opaque orchestration reference and is NOT pollable — poll `GET /business/lists/{listId}` until `completionStatus` leaves `processing`. Errors: - `404` `IMPORT_NOT_FOUND` — importId does not decode to an upload of the token owner. - `404` `LIST_NOT_FOUND` — The destination listId is unknown or not owned. - `409` `LIST_NAME_AMBIGUOUS` — More than one list carries listName — reference the destination by id. - `422` `LIST_NAME_RESERVED` — listName is a system/dynamic list title and cannot be a destination. - `422` `VALIDATION_FAILED` — Neither or both of listId/listName, an unknown body key, an invalid enrich mode, or a malformed mapping. - `429` `RATE_LIMITED` — The lists rate bucket (120 requests/minute, 10,000/day per token owner) is exhausted.

Each key is a column header spelled exactly as it appears in the file (the `headers` of the import preview). Each value is one of exactly these 21 target labels, spelled and cased exactly like this: Full Name, First Name, Last Name, LinkedIn URL, Company, Company Domain, Job Title, Job Level, Department, Industry, Country, State, City, Email, Phone — plus six aliases, each read only when the label it follows is missing or empty: Company Name (after Company), Mobile Phone (after Phone), Seniority then Level (after Job Level), and linkedinUrl then linkedin (after LinkedIn URL). Map to the primary label where you can. A label outside those 21 is ACCEPTED and then silently drops that column — no error, no custom column. Headers that already match a label case-insensitively (email, first_name, title, domain) need no entry, a header with no target carries null and is ignored — so the suggestedMapping from POST /business/imports can be sent back unchanged — and when two headers name the same target only the last one is used. enrich: type: string enum: - none - email - phone - phone_and_email - demographics description: >- Enrichment to run on the imported rows: none (default, rows saved exactly as uploaded), email, phone or phone_and_email (the enrichment waterfall, billed per contact processed) or demographics (resolve rows to canonical contacts, 2 credits per resolved contact). responses: '202': description: Success headers: RateLimit-Limit: schema: type: integer description: Requests permitted in the current window.
