Stored API Keys let you save your API keys once and reuse them across all your flows. Instead of pasting a key into every node, you select a stored key from a dropdown.

​
Adding a Key

1

Open Keys & Connectors

Go to Settings > Keys & Connectors. The Stored API Keys section lists all your saved keys.
2

Click Add API Key

Click the Add API Key button in the top-right corner of the section.
3

Fill in the details

  • Name: A label you’ll recognize later (e.g. “Production OpenAI Key”).
  • Key Type: Select the provider from the dropdown.
  • API Key: Paste your key. The field is masked by default.
4

Store the key

Click Store Key. The key is encrypted and saved. Only the last four characters are shown for identification.

​
Deleting a Key

Hover over a key in the list and click the trash icon. Confirm deletion in the dialog. Any flows that reference the deleted key will need to be updated with a new key.

​
Using Stored Keys in Nodes

Nodes that require an API key, such as Agent, Email (Resend), and Stripe, include a key selector with two modes:
  • Stored: Pick a saved key from a dropdown. If you have stored keys matching the node’s provider, this mode is selected automatically.
  • Manual: Paste a key directly into the field, as usual.
You can switch between modes at any time. When you select a stored key, the node references it by ID so the actual secret is never embedded in your flow configuration.
When you have stored keys available, nodes default to Stored mode so you can get started faster.

​
Security

  • Keys are encrypted at rest and never exposed in the browser after storage.
  • Only the last four characters are displayed for identification.
  • Keys are resolved server-side at execution time. They are never sent to the client or included in exported flow data.
