integration in days

Immediate sandbox access

Sage Active does not provide a free sandbox directly. Maesn provides one at no additional cost, so you can start building and testing your Sage Active integration from day one.

X-OrganizationId setup handled for you

Every Sage Active integration requires a mandatory post-authentication step to fetch and store the correct company identifier per tenant. Maesn handles this entirely during onboarding. No extra setup required on your side.

No GraphQL expertise needed

Building directly on Sage Active means learning GraphQL, Hot Chocolate conventions and complexity limits before writing a single line of business logic. With Maesn, you start with a clean REST API from day one.
