To "delete" an invoice you need to void the invoice.  In src/Journal.php you'll see the implementation of delete which voids a transaction.  This is on the endpoint '/modules/api/journal/'.

The tests are in tests/Journal_Tets.php which demonstrates a full Create Read Update Delete test cycle.

You'll need to do a little research on the $type parameter.  I think "10" is for invoice from memory - not sure.

BTW, I was a contributor to the api back in 2018.

Or hopefully any other developer used it before. They will help you here.

I was trying to delete or cancel the invoice from api.

But i found out that the sample code has disabled the function for demonstrating how to delete with a message that it isn't implemented or tested fully.

        /* Delete is currently untested, and not implemented with standard FA
        // Delete
        $response = $client->delete('/modules/api/sales/' . $id, array(
            'headers' => TestEnvironment::headers()
        ));
        $this->assertEquals('200', $response->getStatusCode());
        $result = $response->getBody();
        $result = json_decode($result);

        // List again
        $response = $client->get('/modules/api/sales/', array(
            'headers' => TestEnvironment::headers()
        ));

        $this->assertEquals('200', $response->getStatusCode());
        $result = $response->getBody();
        $result = json_decode($result);

        $count2 = count($result);
        $this->assertEquals($count0, $count2);
        */

I did further study. i tried to enable the code , It gave me error for loading the class AutoFacturaCore.php.inc .. Which isn't there int he project.

I need to know if there is any update on this
