Setup Guide
Follow these steps to connect Zernio to your instances.1. Create a Zernio account
Sign up at zernio.com. The free plan includes 20 posts per month and supports all 14 platforms.2. Connect your social accounts
In the Zernio dashboard, create a profile and connect your social media accounts via OAuth. Each account gets a unique ID you will use when creating posts. Social account connections require browser-based OAuth and must be done in the Zernio dashboard directly. The agent cannot connect accounts programmatically.3. Generate an API key
Go to Settings → API Keys in the Zernio dashboard and create a new key. Copy it immediately as it is only shown once. Key format:sk_ followed by 64 hex characters.
4. Store the API key in Environment
Go to Environment and create a new variable:- Name:
ZERNIO_API_KEY - Value: Paste your
sk_...API key
5. Grant access to instances
Choose how instances should access this key:- Option A: Global Secret (All instances) — Toggle “Make globally accessible” when creating the secret.
- Option B: Instance-Specific (Selective access) — In Environment, open the secret and grant the specific instance access.
