reCAPTCHA v3 Payment Issue

### Troubleshooting Steps:
1. **Check Payment Gateway Logs:**
– Review logs for specific IP-related errors.
– Confirm if the gateway is blocking requests due to reCAPTCHA.

2. **Test Payment Without reCAPTCHA:**
– Temporarily disable reCAPTCHA to see if payments work.
– If payments succeed, reCAPTCHA is interfering.

3. **Whitelist Payment Gateway IPs:**
– Some payment gateways (like Stripe, PayPal, etc.) validate requests against their whitelisted IPs.
– If your WordPress site sends additional data with reCAPTCHA, the gateway might see it as a security risk.
– Whitelist your **server IP** in the gateway settings.

4. **Verify reCAPTCHA Implementation:**
– Ensure reCAPTCHA is not blocking or modifying API calls made by the payment gateway.
– If using **Cloudflare**, disable "Bot Fight Mode" or "Super Bot Fight Mode," as it can interfere with payments.

5. **Disable reCAPTCHA for Payment Pages:**
– Some plugins allow excluding specific pages from reCAPTCHA.
– Try disabling reCAPTCHA for the **checkout page** and test again.

6. **Check reCAPTCHA Keys & Threshold:**
– If the reCAPTCHA v3 **score threshold** is too high, it might incorrectly flag transactions as bots.
– Lower the **threshold** (default is 0.5) in the reCAPTCHA plugin settings.

7. **Inspect Request Payload:**
– Open **Developer Tools (F12) → Network Tab**.
– Check if reCAPTCHA is adding parameters to payment requests.
– Ensure it’s not interfering with the **gateway’s expected request structure**.

8. **Plugin Conflict Check:**
– Disable all plugins **except WooCommerce and Payment Gateway**.
– Check if the payment works, then **reactivate plugins one by one** to identify conflicts.

### Possible Fix:
– **Exclude Checkout Page from reCAPTCHA v3** (Most reCAPTCHA plugins allow this).
– **Disable reCAPTCHA for API Calls** made by the payment gateway.
– **Contact Payment Gateway Support** to confirm whether they have IP restrictions.

### 🔍 **Troubleshooting Steps**
1. **Check reCAPTCHA v3 Score**
– Some forms require a **lower score threshold** (default is 0.5).
– If users are getting blocked, lower the threshold to **0.3 or 0.2**.
– Adjust this in your **reCAPTCHA plugin settings** (or Google reCAPTCHA admin panel).

2. **Verify Site & Secret Keys**
– Ensure you are using the **correct reCAPTCHA v3 keys** in your plugin.
– If you recently **switched domains** or **migrated** the site, reissue new keys from Google.

3. **Exclude Contact Page from reCAPTCHA**
– Some plugins allow **excluding specific forms** or pages.
– If using Contact Form 7, add this shortcode inside the form:

[recaptcha]

– If using another plugin (e.g., WPForms, Gravity Forms), check its settings for **reCAPTCHA exclusions**.

4. **Check for JavaScript Errors**
– Open **Developer Console (F12 → Console Tab)** in Chrome.
– If there’s a **Google reCAPTCHA error**, it might be failing to load.
– Ensure `www.google.com/recaptcha/` is **not blocked** by Cloudflare or security plugins.

5. **Disable reCAPTCHA v3 for Testing**
– Temporarily **disable reCAPTCHA** in your form plugin.
– Submit the form to see if it works.
– If it does, the issue is **definitely reCAPTCHA-related**.

6. **Use reCAPTCHA v2 ("I'm not a robot")**
– If reCAPTCHA v3 is too aggressive, switch to **reCAPTCHA v2 Checkbox**.
– Go to **Google reCAPTCHA settings**, generate v2 keys, and update them in your WordPress site.

7. **Plugin Conflicts**
– Disable other security plugins like **Wordfence, WP Super Cache, or Cloudflare Bot Protection**.
– If you’re using multiple CAPTCHA plugins, **keep only one**.

### ✅ **Possible Fixes**
✔ **Lower reCAPTCHA v3 score threshold** (e.g., from `0.5` to `0.3`).
✔ **Exclude the contact page from reCAPTCHA v3 checks** (in your plugin settings).
✔ **Use reCAPTCHA v2 instead of v3** if users are frequently blocked.
✔ **Disable Cloudflare’s “Bot Fight Mode”** (if enabled).
