Validate Token Before Use + +```python +def validate_token(token): + try: + # Decode token (without verification for structure check) + import jwt + decoded = jwt.decode(token, options={"verify_signature": False}) + exp = decoded.get('exp') + + if exp and datetime.fromtimestamp(exp) < datetime.now(): + return False + return True + except: + return False +``` + +--- + +## Error Handling + +### Authentication Errors + +**401 Unauthorized**: +```json +{ + "success": false, + "error": "Authentication required", + "request_id": "550e8400-e29b-41d4-a716-446655440000" +} +``` + +**Solution**: Include valid `Authorization: Bearer ` header. + +**403 Forbidden**: +```json +{ + "success": false, + "error": "Permission denied", + "request_id": "550e8400-e29b-41d4-a716-446655440000" +} +``` + +**Solution**: User lacks required permissions.

Implement Token Refresh + +```php +function ensure_valid_token($api) { + // Check if token is about to expire (refresh 1 minute before) + // Token expires in 15 minutes, refresh at 14 minutes + $last_refresh = get_option('igny8_token_refreshed_at', 0); + + if (time() - $last_refresh > 14 * 60) { + if ($api->refresh_token()) { + update_option('igny8_token_refreshed_at', time()); + } + } +} +``` + +### 3. Cache Responses + +```php +function get_cached_keywords($api, $cache_key = 'igny8_keywords', $ttl = 300) { + $cached = get_transient($cache_key); + + if ($cached !== false) { + return $cached; + } + + $response = $api->get('/planner/keywords/'); + + if ($response['success']) { + $keywords = $response['results']; + set_transient($cache_key, $keywords, $ttl); + return $keywords; + } + + return false; +} +``` + +### 4. Handle Rate Limits + +```php +function check_rate_limit($response) { + // Note: WordPress wp_remote_* doesn't expose all headers easily + // Consider using cURL or checking response for 429 status + + if (isset($response['error']) && strpos($response['error'], 'Rate limit') !== false) { + // Wait and retry + sleep(60); + return true; // Should retry + } + + return false; +} +``` + +--- + +## WordPress Admin Integration + +### Settings Page + +```php +function igny8_settings_page() { + ?> +
