# Upgrading an API Key Tier

1. Sign in and create your API key in the [developer portal -> API Keys tab](https://bitbadges.io/developer).

2. Once you've created it and copied it somewhere safe, select "Update Tier".

3. This will take you to the billing page. Select your desired tier. Note that if you have a coupon code, it will typically only apply to a specific tier.

4. Lastly, complete the form, selecting your newly created API key. Enter your email, enter promo code (if applicable), and complete the rest of the form.

5. Once that form is submitted, you're ready to start building! See the [BitBadges API documentation](https://docs.bitbadges.io) for more information on how to use the BitBadges API. The new tier may take 5-10 minutes to register, so please allow some time for the changes to take effect.
