FAQ — Frequently Asked Questions

Do I need a web page for the redirect URI with a desktop application?

No, and you do not need to choose the URI either. Sigabill configures it in the Azure AD B2C tenant when registering your application. You receive the exact value along with your integration credentials, and you simply set it in your MSAL configuration. No web server is required.

Are there API versions?

No. APIs evolve continuously. We are committed to maintaining backward compatibility as much as possible and to communicating changes in advance.

How will I be notified of API changes?

You will receive an email for each change. For more reliable coverage, it is recommended to monitor the Swagger of the environment you consume and to automatically validate your critical scenarios before each release.

How much notice will I get before an API change?

At least 2 weeks before production deployment. Changes are generally available on devtest well before that. To avoid surprises, test your integration regularly against devtest and schedule a validation window on staging before each production release.

An environment seems unavailable — what should I do?

devtest and staging are shared environments used by the Sigabill development team. Brief outages may occur during internal deployments. If the unavailability is prolonged, contact the Sigabill team.
