Fluz API Overview

  1. GET SET UP

Prepare Your Accounts

This is the first step in getting up and running with the Fluz API. Before you can authenticate or make your first call, you need three things: a Fluz account, access to the Developers area, and a registered application that issues your API credentials.

Everything below takes just a few minutes.

📘

Start in the sandbox

All setup happens in Fluz's sandbox (staging) environment first, at uni.staging.fluzapp.com. Sandbox lets you build and test with sandbox keys, test bank accounts, and test card offers — no real money moves. When you're ready to go live, see Staging vs. Live Environment.

Step 1 — Create your Fluz account

The Developers section is where your applications and API credentials live.

Step 2 — Create a new application

Registering an application is what generates the API key and credentials you'll authenticate with. From the Developers section:

  1. Click Create new Application.
  2. Fill in App name and logo, Subtitle, and What is the main purpose of this app?
  3. Click Create new app.
Creating a new application in the Developers section

What you'll have when you're done

  • A Fluz sandbox account with access to the Developers area
  • A registered application
  • Everything you need to retrieve your API credentials

Next steps

With your account and application in place, you're ready to authenticate:

  1. Obtain Your API Credentials — retrieve the API key tied to your application.
  2. Generate a User Access Token — exchange your API key for a scoped token to authorize requests.

See the full Authentication & Authorization Guide for the complete flow.

What you'll set up

  1. A Fluz account — sign up in the sandbox, or log in if you already have one.
  2. Developer access — the Developers section of your account, where applications are managed.
  3. An application — registering an app is what generates the API key and credentials you'll authenticate with.

Step 1 — Create your Fluz account

Sign up for a sandbox account, or log in to an existing one and open the Developers section.

Step 2 — Create a new application

From the Developers section, create an application by giving it a name, logo, subtitle, and a short description of its purpose. Once created, the app holds the credentials you'll use for every API request.

➡️ Create New Application

What you'll have when you're done

  • A Fluz sandbox account with access to the Developers area
  • A registered application
  • Everything you need to retrieve your API credentials
