Building with Lerian

Follow these steps to go from zero to your first double-entry transaction. Choose the path that matches your deployment model.
1

Receive your credentials

Your Lerian onboarding team provides you with API credentials (client ID and secret) and the base URL for your environment.
2

Authenticate and get your token

Use the Access Manager Auth API to exchange your credentials for a JWT access token. This token contains your tenant context — you don’t need to manage a tenant ID explicitly.Learn how to authenticate →
3

Make your first API call

Include the token as a Bearer token in the Authorization header of every request. Your calls are automatically scoped to your tenant.Make your first API call →
4

Create your first organization

Follow the same API flow as any Midaz deployment — create an organization, a ledger, assets, and accounts. The platform handles tenant isolation transparently.Follow the recommended workflow →
The API is identical across all deployment models. The only difference is that SaaS requires authentication on every request, and your token automatically scopes all operations to your tenant. Learn more about multi-tenancy.
