Create function secret

Create a secret for this function. Secrets are injected as environment variables when your function executes.

Use secrets to store sensitive data without hardcoding in function code:

• API keys (Stripe, OpenAI, Twilio, etc.)
• External service connection strings
• OAuth credentials
• Service account tokens

Requirements:

• Function must be in 'deployed' status (422 if not)
• Secret name must be uppercase alphanumeric with underscores (e.g., STRIPE_API_KEY)
• Secret name must be unique within the function

Secret types are automatically detected:

• String values → text type
• Object/array values → json type

Important: The secret value is only returned in the creation response. It cannot be retrieved later. Store the value securely after creation if needed.

After creating a secret, it's immediately available in your function as an environment variable with the specified name.
