Which permissions does Backlinker need?

That access is what lets the article match your store and lets a hosted post go live. You do not provide an API key in Settings.

Search Console is an optional extra on Home, used for the report, not for the placement itself.

The app has four pages: Home, Backlinks, Settings, and Plans. Home can show your Moz Domain Authority and Google Search Console. Backlinks lists each live link, the sentence that contains it, whether it is still verified, and an AI citation score. Settings keeps your shop name, notification email, and saved defaults.

Each backlink costs 20 credits, and the image is included. Free includes 30 credits, enough for one backlink. Starter is $29 a month or $290 a year for 150 credits. Professional is $59 or $590 for 300 credits. Enterprise is $119 or $1,190 for 600 credits, which is 30 backlinks. Yearly billing is 17% less and appears as -17% next to Yearly.

If another store's article is published on your blog, you earn credits once from your Moz Domain Authority, at least 10 and at most 100, plus 5 credits each month that post stays live. Those credits are already in your available balance. If you have fewer than 20 credits, Backlinker stops before any other work and emails you at most every three days. It also emails you when a backlink is published.
