Edge

extport publishes to Edge Add-ons using Partner Center’s Submission API.

Credential fields

Under Settings → Store credentials → Edge, extport asks for:

Field	Where it comes from
Client ID	Partner Center → Edge → Publish API → Client ID
API Key	Same page → New API key

A single Client ID/API key pair covers every extension on that Partner Center account — you don’t need one per extension.

Product id and crx id

Edge is the one store with two different ids for the same listing:

Field	Used for	Where it comes from
Product ID	Required — the Submission API’s internal GUID	Partner Center → your extension → Extension identity
CRX ID	Optional	The store-facing id shown on the extension’s public Edge Add-ons page

Product ID is what actually publishes; CRX ID only helps extport detect the live version between reconcile ticks when the Submission API itself can’t report status.

For example, Redirector’s Edge listing has Product ID fc0018c2-ecb8-4305-8ccf-b700cc62aba7 and CRX ID jhdjcofnjfeljeekjklhgfmfocfgibmm — the CRX ID is also the trailing segment of its public listing URL, microsoftedge.microsoft.com/addons/detail/redirector/jhdjcofnjfeljeekjklhgfmfocfgibmm.
