Gainsight API access key is a unique access key used for authentication of Gainsight REST API requests. Gainsight Admins generate this access key from the Connectors 2.0 page and is consumed by developers to pass this in the request header “Accesskey” for all the API requests into Gainsight. To generate an access key, navigate to Administration > Integrations Connectors 2.0 > Connectors tab > Gainsight API Widget. 

Admins can create only one Access Key per org and it does not expire. Gainsight authenticates REST API requests by verifying this access key and if the authentication succeeds, access to Gainsight platform is granted to developers. You can reset the existing access key anytime, but the new access key should be replaced in headers of all the future API requests.
