Create an IONOS API key

This article walks you through generating an API key in IONOS so you can connect it to InfraNest for managing DNS, domains, and certificates.

Overview

• InfraNest uses a single IONOS API key to handle DNS, domains, and certificates for your account.
• You'll generate this key directly in the IONOS console, then bring it back to InfraNest to finish the connection.

Create the key

1. Go to developer.hosting.ionos.com and sign in.
2. Create an API key.

3. Your key has two parts — a prefix and a secret — shown together as prefix.secret.
4. Copy the whole value, including the part before the dot.

WarningCopy the full prefix.secret value. Leaving off the prefix (the part before the dot) is the most common cause of an "authentication failed" error.

Next step

Go back to InfraNest and follow Connect IONOS to paste your key.
