Using tokensLink to this anchor

To use the token, you have to add the generated token to an X-Auth-Token header.

To execute a private function by providing a token using curl, run the following command:

curl -H "X-Auth-Token: <YOUR_FUNCTION_TOKEN>" <YOUR_FUNCTION_ENDPOINT>

A private function observes this behavior:

• If a call is made without the X-Auth-Token header, the call is rejected (status code 403).
• If a call is made with the X-Auth-Token header, the token is validated using a public key attached to the namespace.
