Use a HAWI developer sandbox

Sandboxes are separate, isolated spaces with sample data and test credit that has no monetary value.

A developer sandbox is a separate, isolated space, not a setting you add to a request. Development credentials cannot access production customer data. Seeded records are synthetic, payment flows use test or fake billing, and reset requires confirmation. Production personal data is excluded by default.
