Codeigniter 4 redirecting POST request to "/" when call made from cURL

I found the issue! It was the CSRF protection. I just had to update it to exclude API calls:

public $globals = [
'before' => [
// 'honeypot',
'csrf' => ['except' => ['api/*]],
// 'invalidchars',
],
'after' => [
'toolbar',
// 'honeypot',
// 'secureheaders',
],
];
