API Key has Stopped Working

An API key will stop working in the following situations:

• It was manually revoked by the key's owner
• The API access was turned off by a team administrator
• The password of the account it was linked to was changed

For security reasons, changing your password will require you to re-authenticate on other sessions. This includes mobiles apps such as the D4H Equipment Management app, the Personnel & Training app and third parties, as well as other connected services like ConnectRocket. 

If you need to (re) create an API key, see How do I obtain an API access key?
