Sends browser-collected conversion events through Scalev using the Meta pixels configured on the store's hosted storefront analytics setup. The store path selects the storefront; do not send a custom domain to identify the store. A `204` means the payload was accepted for asynchronous delivery. ## OpenAPI ````yaml https://api-openapi.scalev.com/specs/v3/openapi.json post /v3/stores/{store_id}/public/analytics/meta/events openapi: 3.0.3 info: title: Nexus Commerce API version: 3.0.0 description: > Public v3 commerce contract for storefront, customer, and authenticated business commerce flows. This specification intentionally documents only the `/v3` namespace. Store-derived public storefront routes under `/v3/stores/{store_id}/public/*` require `X-Scalev-Storefront-Api-Key`. HTML Mode public page runtime routes under `/v3/pages/{page_unique_id}/*` require `X-Scalev-Page-Api-Key` and do not accept storefront public API keys. Storefront API requests made with `X-Scalev-Storefront-Api-Key`, page runtime requests made with `X-Scalev-Page-Api-Key`, and guest-cart requests made with `X-Scalev-Guest-Token` are browser client requests and use the direct client/IP rate limiter. Machine-authenticated business requests are rate-limited per API key or OAuth installation. Rate-limit metadata is returned in `X-Ratelimit-*` headers, and `429` responses may be plain text. license: name: Proprietary servers: - url: https://api.scalev.com description: Production security: [] tags: - name: Orders description: Authenticated business order management endpoints. - name: Storefront description: >- Public storefront catalog, guest cart, and guest checkout flows.
