Virtual Try-On API

Build Virtual Try-On integrations with HeadSwap. Review authentication, request parameters, task creation, status, and result endpoints.

Overview

Generate a realistic preview of a person wearing a specific garment from a product image - no physical samples required.

Primary Endpoint

POST/api/v1/virtualTryOn/start

Start a virtual try-on task with clothing images on person photos. ### Request - Send a valid bearer token. The server evaluates the operation in the authenticated caller's access context. - Send an `application/json` body. Required fields: `image_urls`. - API-token callers may include `webhook_url` and `webhook_token` for best-effort terminal-state notifications; ordinary JWT/cookie calls ignore these fields. ### Behavior - This is an asynchronous operation: a successful submission creates a task and returns before processing finishes. - Persist the returned task identifier and use the corresponding detail or list operation to observe progress. - Treat the detail endpoint as the source of truth even when webhook delivery is enabled. ### Response - A `200` response confirms task acceptance; it does not by itself mean media generation has completed. - Retain the returned identifier and wait for a documented terminal status before using output URLs. - JSON object responses, including error responses, normally carry a top-level `trace_id` string for this request; include it when contacting support. It is not a task identifier. - Do not infer undocumented fields or statuses; clients should tolerate additional response properties. ### Errors - `400` — Bad Request - Invalid parameters. - `401` — Unauthorized - Invalid or missing JWT token. ### Related Operations - `GET /api/v1/virtualTryOn/allRecords` — Get all virtual try-on records. - `GET /api/v1/virtualTryOn/{_id}` — Get virtual try-on task detail. - `DELETE /api/v1/virtualTryOn/{_id}` — Delete virtual try-on task. Authentication: set header Authorization: Bearer <token> (supports user JWT or sk_ API token).
