Why is my AI tool returning UNAUTHORIZED errors after using my 101domain API key?

If your AI integration suddenly stops working, start by checking your API key settings in your my101domain.com account. Your API Key may have expired.

API keys have a fixed lifespan of 7 days to one year, depending on the option you selected when you created the key. If your calls are now failing, the key may have:

  • Reached its expiration date, or

  • Been revoked by your Primary Account User.

You should also confirm that the API key stored in your AI platform or automation tool is still an exact match.

If even a few characters are changed or removed (for example, during a copy‑and‑paste or configuration edit), the key will stop working immediately and all requests will fail.

API Key Expiration Periods can be set to:

  • 7 days

  • 30 days

  • 90 days

  • 1 year


How to resolve

If your key has expired, you have two options:

  1. If you have less than 10 API Keys, create a new API Key.

  2. If you have 10 API Keys, you will need to revoke an existing key (even if it is expired) and then create a new API Key.

You can only create a maximum of 10 API Keys.

In all cases, update your environment. Replace the old key in your application’s .env file or configuration settings (for example, the Authorization: Bearer [YOUR_NEW_API_KEY] header), then restart your services so the new key takes effect.
