Getting started

This guide takes you from zero to your first successful API call. The whole process usually takes less than 24 hours.

1. Request access​

Fill in the access request form with your name, business email and company. The NextUp team reviews the request and replies by email, usually within 24 business hours.

tip

Tell us briefly how you intend to use the API (e.g. "sync stock with our WooCommerce store"). It helps us prepare the right environment for you.

2. Receive credentials email​

If your request is approved, you receive an email with:

  • your login email;
  • a temporary password.

Keep these confidential — you use them once, on your first login.

3. Log in + change password​

Go to the login page and sign in with the credentials you received. On first login you are asked to set a new password (at least 10 characters). You are then redirected back to the Explorer.

4. First call in Explorer​

In the Explorer:

  1. Select the Sandbox environment (test data, no risk).
  2. Click Authenticate & set token — the token is filled in automatically.
  3. Expand the GetAuthenticationToken operation (or any other method) and click Try it out → Execute.

That's it — you've made your first call! From here you can explore all 107 operations in the API Reference.

Sandbox vs Live

The Sandbox environment runs on a Mock Server with test data — ideal for integration and experiments. The Live environment sends real calls to your production ERP; use it only when you're ready. See Authentication for details.
