Visit the links below to understand how each process works:

• API user creation
• API user authentication

Overview

The API communication between the customer backend and the Fireblocks platform takes place over HTTP (REST). The authentication mechanism is done by creating an API user and signing a JSON Web Token (JWT) for each request made by the customer.

API roles

The Fireblocks NCW feature comes with two new API roles: NCW Admin and NCW Signer.

NCW Admin

This role is used for general workspace operations, such as creating a new NCW.

NCW Signer

This role is used for specific wallet operations, such as creating a transaction from a specific NCW.

Role permissions

The table below lists the different operations that can be executed by the NCW Admin & NCW Signer API users.
