How it fits an integration
One key, sent from your server, covers sending, scheduling and reading statuses. There is nothing to install and no SDK you are forced to adopt.
Cost is the same as the interface
API traffic is priced exactly like traffic sent from the workspace: one published price per segment in EUR per destination, reserved before the job runs.
Security
Keys belong on your server, in a secret store. A key can be replaced at any time with no downtime if you deploy the new one before deleting the old.
