3. Copy and store your **API Key** in a safe place. You will not be able to see it again after creation. If you lose it, create a new one.

<Tip>Currently, API keys are created in the context of your own user. Fine-grained permissions may be added by Tally in the future.</Tip>

#### Step 2: Enter credentials in the Connect UI

Once you have your **API Key**:

1. Open the form where you need to authenticate with Tally.
2. Enter your **API Key** in the respective field.
3. Submit the form; you should then be successfully authenticated.
