$response = $client->post( $endpoint, [ 'json' => $content, 'headers' => $headers, 'connect_timeout' => 650, // add these 'cert' => '/path/to/openyes.crt.pem', 'ssl_key' => '/path/to/openyes.key.pem' ]);if they have a pass phrase, you can set them like this:
'cert' => ['/path/to/openyes.crt.pem', 'password'], 'ssl_key' => ['/path/to/openyes.key.pem', 'password']
