Integrations and source ownership

• Public league website. Publish the fixture schedule and the standings from confirmed results.
• Email and messaging. Send fixture changes, official assignments and training reminders.
• Live scoring app. Send final scores as submitted results for confirmation.
• Registration payments. Record team fees through your payment provider before approval.
• Calendar. Share fixtures and training sessions with coaches and officials.

Each connection needs an agreed source of truth, a field mapping, a stable identifier and a retry policy. A repeated score message must not create a second result, and the public table must show confirmed results only. Keep credentials in the approved secret store and grant the smallest scope the connection needs.

Test a timeout, a duplicate message and a revoked credential before turning on schedules. Availability depends on each provider’s API, commercial access and configuration.

Use the implementation plan to agree acceptance criteria for each connection.
