If Apps are not enabled on your account, please contact our support team ( https://zingfithelp.zendesk.com/hc/en-us ) so we can get that setup for you. Apps will only be enabled for users in the Admin role.
Once Apps are enabled, you can find them by going to Admin > Configuration > Apps.
There you will see which App Integrations are available to you. If you do not see an App Integration you are looking for, or it isn't possible for you to Enable it, please contact our support team so we can discuss it with you.
You can Enable an available App Integration by clicking on the grey Enable button. This will then show a date in the Date Added column, as well as a blue avatar next to the App Integration you enabled.
By clicking on the blue avatar, you will be shown the credentials for that App Integration: a Client ID, a Secret Key, and a Tenant ID. You will need to share these with the 3rd party you are integrating with via this app integration.
When you are ready to disable a particular app integration, simple click on the red Remove button.
