The connector variables tab displays any instance-level, shared variables that you defined in Step 2: connector variables - for example:
If you want to use any of these variables in this authentication method, click the use button:
This copies the variable into the auth variables tab - for example:
From here, the variable is treated like any other auth variable - you will need to set options to determine if/how this variable is displayed to users, and how any values for it should be passed in API requests for authentication.
If you choose to use a connector variable- i.e. to copy it to the auth variables tab - but later change your mind - you can remove it by clicking the associated trash icon on the auth variables tab - for example:
This clears the connector variable from the auth variables tab but the original 'shared' connector variable remains available for future use.
