If the Search Atlas WordPress plugin displays "The API key could not be verified," follow the fixes below to identify the cause and restore your connection — most cases are resolved in under five minutes.

⚠️ Common Causes of This Error

Verification fails when the plugin cannot authenticate your API key with Search Atlas. The most frequent causes are:

  • Incorrect or incomplete API key — a typo, extra space, or truncated string.
  • Expired or rotated key — the key was regenerated in the dashboard but the plugin still holds the old one.
  • Server blocking outbound HTTPS requests — a firewall, security plugin, or hosting restriction prevents your site from reaching api.searchatlas.com.
  • Invalid SSL certificate — the plugin communicates over HTTPS; a broken certificate blocks the verification request.
  • Outdated plugin or stale cache — an older plugin build or cached response interferes with authentication.

🔑 Fix 1 — Confirm and Re-enter Your API Key

A typo or extra whitespace is the most common cause. Copy the key directly from your dashboard to eliminate manual-entry errors.

  1. Log in to your Search Atlas dashboard.
  2. Go to Settings → API Keys and click the copy icon next to your key — paste the value rather than typing it.
  3. In WordPress admin, go to Search Atlas → Settings and clear the current value from the API Key field.
  4. Paste the copied key and click Save Settings.

You'll see a green "API key verified" confirmation when the key is accepted. If the error persists, continue to Fix 2.

🔄 Fix 2 — Regenerate Your API Key

If the key looks correct but still fails, it may have been invalidated — for example, after a recent rotation or an account plan change.

  1. In your Search Atlas dashboard, go to Settings → API Keys.
  2. Click Regenerate Key to issue a new API key.
  3. Copy the new key immediately — it is displayed only once.
  4. In WordPress admin, go to Search Atlas → Settings, replace the old key with the new one, and click Save Settings.

The plugin confirms a successful connection once the regenerated key is accepted.

🛡️ Fix 3 — Check Server Connectivity and Outbound Access

Your WordPress server must be able to make outbound HTTPS requests to api.searchatlas.com. Firewalls, security plugins, or restrictive hosting environments can silently block these requests.

Disable security plugins temporarily

  1. Deactivate security plugins such as Wordfence or iThemes Security.
  2. Retry the API key verification in Search Atlas → Settings.
  3. If the key verifies, add api.searchatlas.com to that plugin's allowlist, then re-enable it.

Confirm outbound HTTPS with your hosting provider

  • Contact your host and ask whether outbound connections to external APIs on port 443 (HTTPS) are permitted from your server.
  • Request that they whitelist api.searchatlas.com if outbound traffic is restricted at the server level.

Verify that PHP cURL is enabled

cURL is the PHP extension the plugin uses to make API requests. Confirm it is active before retrying verification.

  1. In WordPress admin, go to Tools → Site Health → Info → Server.
  2. Confirm cURL appears in the extensions list with a status of enabled.
  3. If cURL is missing or disabled, contact your hosting provider to enable it.

Once connectivity is restored, retry saving your API key in Search Atlas → Settings. The plugin will connect as soon as your server can reach Search Atlas.

🔁 Fix 4 — Clear Caches and Update the Plugin

Stale cached responses or an outdated plugin build can prevent the verification request from completing correctly.

  1. In WordPress admin, go to Plugins → Installed Plugins and check for a pending update to the Search Atlas plugin. Install any available update.
  2. Deactivate your caching plugin (e.g., WP Rocket, W3 Total Cache, LiteSpeed Cache) and purge all cached files.
  3. Go to Search Atlas → Settings, re-enter your API key, and click Save Settings.
  4. Re-enable your caching plugin only after the key is successfully verified.

Running the latest plugin version with a clean cache ensures the verification request reaches Search Atlas without interference.

⚙️ Fix 5 — Resolve SSL Certificate Issues

The Search Atlas plugin sends all API requests over HTTPS. If your site's SSL certificate is invalid, expired, or missing, the verification handshake will fail before it reaches Search Atlas.

  • Open your site in a browser and confirm the padlock icon appears in the address bar. A warning triangle means the certificate is broken or untrusted.
  • If your certificate is expired or misconfigured, contact your hosting provider to renew or reinstall it.
  • If your WordPress site still runs on HTTP, update both URL fields to HTTPS at Settings → General → WordPress Address (URL) and Site Address (URL).

Once your site has a valid SSL certificate, the plugin can establish a secure connection to Search Atlas and complete verification.
