What is API Key?
The credential identifying your account to a translation API; you control quotas, billing and restrictions.
In more depth
Restrict keys to the Translation API and your server's referrer/IP to prevent abuse.
Why it matters for your website
Understanding API Key helps you make better decisions when taking a WordPress site multilingual — from choosing URL structures and engines to controlling costs. Transxlate handles the mechanics (language URLs, lang attributes, caching, hreflang on Pro) so terms like this become settings, not engineering projects.
