Invalid API key error in IntelliWP

May 21, 2025

The “Invalid API Key” error is common when setting up IntelliWP. First, verify that you\’ve copied the complete API key from OpenAI without extra spaces and that the format matches OpenAI\’s standard (starts with “sk-“). Navigate to WordPress Admin → IntelliWP → Settings, clear the existing API key field completely, paste the fresh API key, and save the plugin settings.

Also confirm that your OpenAI account is active and verified, with a valid payment method and sufficient credits. If the problem persists, check if your hosting provider blocks OpenAI API requests, update the plugin to the latest version, and review WordPress error logs. For enterprise implementations, consider setting up connectivity monitoring and regular key rotation for enhanced security.
