Last updated 20 June 2026
API Key is wrong or user disabled
In short
This error means AutoTrader Web could not authenticate the user. It happens when the API key used is wrong, or when the user has been disabled. To fix it: log out and log back in if you just regenerated the key, set the correct key from Settings -> Security, or contact support if your user was disabled (usually after an API limits breach).
When this happens
- 1 The API key used by the user is wrong.
- 2 The user has been disabled by AutoTrader Web, usually after an API limits breach.
What is the API key?
The API key of AutoTrader Web is a unique secret key given to the user. AutoTrader Web APIs use it for authentication.
Users can call the AutoTrader Web APIs directly through various tools or libraries. The same key is also used by AutoTrader Web’s PMS web application.
