Output

Each key shows its name, ID, masked prefix, mode, creation date, and last used timestamp: 
✓ Found 3 API keys

Full key values are never displayed after creation. The list only shows the prefix with the rest masked. This is a security measure — keys are hashed with SHA-256 and Argon2 on the server side and cannot be retrieved.

​
keys create

Create a new API key with an interactive wizard. 
zendfi keys create [options]

​
Options

FlagDescriptionDefault
--name <name>Key nameInteractive prompt
--mode <mode>Key mode: test or liveInteractive prompt

​
Interactive Flow

$ zendfi keys create

Create New API Key

? Key name: Production API
? Key mode: Live - For production use
? Create LIVE API key named "Production API"? Yes

✓ API key created successfully!

Key Details:
  Name:  Production API
  Mode:  LIVE
  ID:    key_abc123

  Save your API key - it won't be shown again!

  zfi_live_sk_8f3k9x2m4n7p...

? Save to .env file in current directory? Yes
  ✓ Saved to .env

​
.env File Handling

When you choose to save the key, the CLI writes it to .env in the current directory:
  • If the file already contains ZENDFI_API_KEY (for live keys) or ZENDFI_TEST_API_KEY (for test keys), it updates the existing value.
  • If the file does not exist, it creates one.
  • Live keys are stored as ZENDFI_API_KEY, test keys as ZENDFI_TEST_API_KEY.

​
Non-Interactive Mode

zendfi keys create --name "CI Pipeline" --mode test
You will still be prompted for final confirmation unless you pipe stdout (the safety confirmation cannot be skipped).

​
keys rotate

Rotate an existing API key. This generates a new key value and invalidates the old one. 
zendfi keys rotate <key-id>

​
Arguments

ArgumentDescriptionRequired
key-idThe key ID to rotate (e.g., key_abc123)Yes

​
Example

$ zendfi keys rotate key_abc123

Rotating API key key_abc123...

✓ Key rotated successfully!

  New key: zfi_live_sk_new_value_here...

  Update your environment variables with the new key.
  The old key is now invalid.
Rotation is immediate and irreversible. The old key stops working as soon as the new key is generated. Update all services using the old key before rotating, or prepare for a brief interruption.

​
Security Notes

  • Key values are shown once. When you create or rotate a key, the full value is displayed exactly once. After that, only the prefix is available through keys list.
  • Test vs. Live isolation. Test keys (zfi_test_) only work against Devnet. Live keys (zfi_live_) only work against Mainnet. They cannot be used interchangeably.
  • Rate limits apply. API key operations are rate-limited. See the API Keys reference for rate limit details.
  • Scoped keys. Keys can have scoped permissions (read-only, payments-only, etc.). Scoped key management is available through the dashboard or API. The CLI creates full-access keys by default.

​
Workflow Tips

​
Multiple environments

Keep separate keys for development, staging, and production: 
# Create a key for each environment
zendfi keys create --name "Development" --mode test
zendfi keys create --name "Staging" --mode test
zendfi keys create --name "Production" --mode live

​
Key rotation schedule

Rotate keys periodically as a security best practice. The CLI makes this straightforward: 
# List keys to find the ID
zendfi keys list

# Rotate the target key
zendfi keys rotate key_abc123

# Update your .env / secrets manager with the new value
