Google reCAPTCHA (Invisible v2) can prevent bots from entering your giveaway forms without adding friction for real users.

1) Create your reCAPTCHA keys in Google

1. Open the reCAPTCHA Admin / Google Cloud reCAPTCHA console and create a new key.
2. Type: choose reCAPTCHA v2 → Invisible reCAPTCHA badge (this is the one supported by the "Enable Invisible reCaptcha" toggle you see in Giveaway Ninja).
3. Domains: add every domain where your giveaway/entry form can appear (e.g., yourstore.myshopify.com and your custom storefront domain). If you are using our Direct URL feature, also add giveaway.ninja in the list.
4. Save to get your Site key and Secret key.

2) Paste keys into Giveaway Ninja

1. In your Giveaway Ninja dashboard, open Edit Giveaway → Security → reCaptcha.
2. Toggle Enable Invisible reCaptcha ON.
3. Paste your Site key and Secret key into the matching fields.
4. Save.

That's all—Giveaway Ninja will call Google behind the scenes; legitimate users usually won't see any puzzle, while suspicious traffic may be challenged.

PLEASE NOTE: Test it live before publishing the giveaway; if you can't enter there is a problem with the keys. In that case, check your browser's console log to see the exact error.
