Data Events

We are using the FetchConnectedSiteInfo FluxC endpoint temporarily do a pre-check on the url entered in LoginSiteAddressFragment.

LOGIN_CONNECTED_SITE_INFO_REQUESTED(url)

• We sent a request to FluxC to validate the URL

LOGIN_CONNECTED_SITE_INFO_FAILED(url, error, message)

• The request to validate URL did not complete for some reason. This could be something like a network issue.

LOGIN_CONNECTED_SITE_INFO_SUCCEEDED(url, exists, hasJetpack, isJetpackActive, isJetpackConnected, isWordPress, isWPCom, jetpackVersion, skipRemoteInstall)

• The request to validate the url succeeded. This does not mean the URL is valid, it only means we were able to successfully validate it.

Site picker screen & Auto Login
