      **Endpoint Migration:** The `/v1/automations` endpoints have been renamed
      to `/v1/payment-routes`. The old `/v1/automations` paths remain available
      as deprecated aliases during migration. Update your integrations to use
      `/v1/payment-routes` as the deprecated endpoints will be removed in a
      future release.
  - name: simulate
    description: >-
      Transaction simulation endpoints for testing integration flows in
      non-production environments. These endpoints let you trigger transaction
      events programmatically to automate integration tests and verify webhook
      handling without depending on external systems or staging real deposits.
      **Sandbox only** — all simulation endpoints return `404 Not Found` in
      production.
  - name: raindrops
    description: >-
      Rewards and points management endpoints. Custom API keys need
      `raindrops:read`/`raindrops:write` for general rewards endpoints and
      `raindrops-travel:read`/`raindrops-travel:write` for travel redemption
      endpoints.
