A credential is a connected account or API key. You connect a service once, then reuse that credential across every workflow and node that needs it.

Connect from a node

1

Open the node's Credentials tab

Click the node, then open the Credentials tab (K) in the config panel.
2

Pick or create a credential

Choose an existing account from Select credential…, or create one in place. The dropdown’s footer offers Connect new for OAuth services and Create new for API-key services.
3

Complete the connection

For OAuth, a provider sign-in window opens; approve access and the window closes. For API keys, paste your key into the form. Either way the new credential is selected on the node automatically.

OAuth services

Around 25 services (Google, Slack, GitHub, Notion, X, and more) connect with a browser consent flow: click Connect [Service] Account, sign in, approve the requested permissions, done. NoClick stores the resulting tokens and refreshes them automatically, so you don’t need to reconnect when they expire. A few providers ask for one extra detail before the sign-in window opens, like your Shopify store name or your Jira site.

API-key services

Other services use a key you paste in. The form lists exactly the fields the service needs, and most include a Get your API key here link that takes you to the provider page where the key is issued.
WhatsApp is the exception to both patterns: it connects by scanning a QR code with your phone.

Manage credentials in Settings

Settings → Credentials lists every credential you can use, grouped into Personal, Shared With Me, and (when you’re in an organization) Organization tabs. From here you can search, create credentials with New credential, share a credential, or delete one.

To rename a credential or replace its key, select it on a node and use the Edit credential button next to the picker. Existing secret values are never shown back; you re-enter them when updating.

Per-plan limits

Each plan caps how many credentials you can hold per service:

Plus3
ProUnlimited
EnterpriseUnlimited
Hitting the cap shows an upgrade prompt when you try to connect another account of the same type.
