# Create application

> Create a new underwriting application with business, stakeholder, and financial details using GraphQL.

The first step in the underwriting process is creating an application. This establishes a new record in the Tesouro platform, allowing you to progressively add business, stakeholder, and financial details before submission.

### Create application mutation

Use the [`createUnderwritingApplication`](/underwriting/reference/graphql/operations/createunderwritingapplication) mutation to create a new underwriting application.
