The Plugin Integration API v1 is now available in private beta for partner plugins on Saleor, Shoper, PrestaShop, Shopify, and other e-commerce platforms.
The new surface lets a plugin authenticate with a scoped API key, submit single jobs or batches, poll status, mint presigned URLs for uploads and outputs, and receive HMAC-signed webhooks when jobs complete. Idempotency keys, per-installation rate limits, dual-signing rotation grace, automatic retries, and a circuit breaker that pauses unhealthy callbacks are all built in.
Documentation, the OpenAPI 3.1 contract, copy-paste curl examples, and the sub-processor list are available at /docs/plugin-api. Plugin developers can request beta access through their account manager.
