Amazon connection
Whether this account's connection to Amazon is actually working, region by region, and when it was last proven good — separately from whether the credentials were merely entered.
Region
Which of Amazon's three SP-API regions (North America, Europe, Far East) this row's credential authorises against.
Good: Not a figure — one row per region this account has connected. A marketplace not appearing here yet needs its own authorisation even if others already work, because a token issued for one region is rejected by another.
From: tenant_credentials.region, queried in public/connect.php and filtered to exclude the "ads:" prefix reserved for advertising credentials.
Seller
Amazon's own seller id for the account connected in this region.
Good: Not a figure to judge — useful for confirming this connection points at the Seller Central account you meant, especially where more than one exists.
From: tenant_credentials.selling_partner_id, filled in the first time a token from that region is verified — see try_token() in public/connect.php.
Status
Whether Amazon is still honouring this region's refresh token.
Good: "active" needs nothing. Anything else means the token has started failing — read the error line beneath the row, which carries Amazon's own message, and reconnect that region from the form above.
From: tenant_credentials.status, set to "active" on a successful check and read back in the credentials table in public/connect.php.
Last verified
The last time Amazon actually accepted this region's token — not when it was first entered.
Good: A connection not verified in a while, with no failed status yet, is not necessarily wrong — it simply has not been asked again recently. A row carrying an error message beneath it is the one that needs attention, not this date on its own.
From: tenant_credentials.last_ok_at, formatted by rel_time() in public/connect.php.
