Try It on every API reference endpoint

API

Every endpoint page in the API reference now has an Example / Try it tab strip in the right pane. Pick the verb you care about, paste an API key, fill in the path/query/body, and hit Send — the request runs from your browser straight against the live API and the response renders inline. The Example tab (the static curl snippet) is unchanged and stays the default view.

PATs accepted on product endpoints and store updates

API

/v1/products* and PATCH /v1/stores/{storeId} now accept Personal Access Tokens in addition to API keys. PATs use the user's role in the bound store — Owner/Admin can write, Viewer is read-only — so the documented "read-only on store resources" caveat is gone. When using a PAT against a route that doesn't carry a store id in the path (like /v1/products), pass the store you want via the Mercel-Store-Id: str_… header; the Try it panel now exposes a Store ID input for this.
