Overview
To authenticate with AltTextLab, you need:- API Key — an AltTextLab API key.
Prerequisites
- An AltTextLab account. You can start free with 25 credits. If you don’t have an account, sign up.
Step 1: Create an API key
- Sign in to the AltTextLab dashboard.
- In the left sidebar, under Connect, click API keys (direct link).

- Click Create API key.

- Enter a name for the key. You can also set a monthly usage limit, or leave it at No limit. Then click Create key.

- Click Copy to copy the key and save it right away. It is shown only once.

Step 2: Enter your API key in the Connect UI
- Open the form where you need to authenticate with AltTextLab.
- Enter your key in the API Key field.
- Submit the form. The connection is saved without checking the key: if the key is wrong, the first API request returns an authentication error.
