Your Tenant ID is the unique identifier for your AEvent account. It is the subdomain on every link AEvent hosts for you, the part right before .aevent.online, and it tells AEvent which account a request belongs to. You will need it any time you work with AEvent at the link or API level.
Where to find your Tenant ID
In your AEvent dashboard, open the account menu in the upper-right corner.
Click Account Settings.
Copy the Tenant ID value.
Your Tenant ID is also the subdomain of your registration links, the part right before .aevent.online.
What your Tenant ID is used for
You use your Tenant ID any time you build an AEvent link or make an API call by hand. For example:
Registering people through the API. The endpoint is
https://TENANT_ID.aevent.online/api-registration. See API Registration for AEvent.Building a registration link by hand, such as adding
show=allto reach a hidden date. See Register Into a Hidden or In-Progress Webinar Date.Unsubscribing a registrant through the hosted page or the Unsubscribe API at
https://TENANT_ID.aevent.online/unsubscribe-registrant. See Unsubscribe Registrant.
Most of the time AEvent fills your Tenant ID in for you inside the app. You only need to copy it when a setup step or tutorial asks for it directly.
