1. Identify the API and version relevant to your integration in the API catalog.
2. Review its linked OpenAPI reference for endpoint paths, required schemas, and responses.
3. Obtain the appropriate API credentials and permissions through your Sysone contact.
4. Configure your application for the assigned environment and follow the API's own authentication requirements.
5. Test with approved non-production data before requesting production access.
