Platform:

• Unleashed on Browser 

Answer: 

There is no way of changing or refreshing the API Key and ID for Unleashed accounts. 

Additional Information:

Our developers suggest that the best practice is always to create a trial/sandbox account and ask your 3rd party developer to work on them instead of your live account. 

Once the development work is done, you can then apply the live account API key for the integration ensuring it is never shared with the 3rd party developer.
