Headers & Authentication

Learn how to add custom headers and authentication to your scheduled webhooks.

Adding Headers

When creating a webhook, add headers one at a time:

1. Enter header name (e.g., Authorization)
2. Enter header value (e.g., Bearer your-token)
3. Click Add
4. Repeat for additional headers

Common Authentication Patterns

Bearer Token

Authorization: Bearer eyJhbGciOiJIUzI1NiIs...

API Key

X-API-Key: your-api-key-here

Basic Auth

Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=

The value is base64(username:password)

Content Type

RunLater automatically sets Content-Type based on your selection:

• application/json (default)
• application/x-www-form-urlencoded
• text/plain
• text/xml

Security Best Practices

• Use HTTPS endpoints only
• Rotate API keys regularly
• Use the minimum required permissions
• Don't share webhook URLs publicly

Debugging Auth Issues

If you're getting 401/403 errors:

• Check the header name spelling (case-sensitive)
• Verify the token hasn't expired
• Ensure no extra spaces in values
• Check the API documentation for required format
