➕ Create a Contract

In SPACE, contracts represent the legal and technical agreements between the SaaS provider (who manages SPACE) and the end users of the SaaS application.
They define who the customer is, what are they subscribed to, and how billing is managed.

Unlike services or pricings, contracts can only be created programmatically via the SPACE API. It is an action that is expected to be performed by the managed service programmatically.

📖 Example Scenario​

Suppose a customer has purchased the GOLD plan of PetClinic.
After verifying their payment in your billing system, you must register the contract in SPACE so that:

  • The subscription state can be tracked.
  • Feature access can be enforced.

🧾 Required Fields​

To create a contract, you need to provide:

  • User Information: at least userId and username of the subscriber.
  • Billing Period: renewal policy (autoRenew) and cycle length (renewalDays).
  • Contracted Service(s): the service(s) and pricing version(s) the contract refers to.
  • Subscription Plans: which plan the user has subscribed to for each service.
  • Subscription Add-ons (optional): any additional features the user purchased.

For more details on the contract schema, see the API Reference.

0. Prerequisites​

  • A valid API key with at least the MANAGER role. See SPACE Roles for details.
  • The userId of the subscriber. This depends on the identification system the managed service employs.

Notes
  • usageLevels are automatically initialized and tracked by SPACE.
  • history will contain the lifecycle events of the contract (e.g., upgrades, downgrades, cancellations).
  • Contracts are immutable in principle: any change creates a new version in the history log.
