Service accounts let you programmatically access and alter the building blocks, such as listing all users, creating products or deleting webhooks. Each building block has a section specifying the actions you can do with the admin role.
To get started with a service account, go to settings in your dashboard and generate a new service account. You will also need an API key. Add these to your header in your requests and you are ready to go:
X-Builton-Api-Key: <builton-api-key>Authorization: Bearer <service-account-key>
