API enabled but not working

Hello, I’ve already installed beeweb module to magento, attributed reading Guest roles in system config, and installed mag-integration to wp, htaccess is just fine as the rewrite rule for /api/rest/ is uncommented and directly under ‘#RewriteBase /magento/’, yet I can’t connect to magento api. And both api modules are enabled in configurations.

Server is Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips PHP/5.6.40, has mod.rewrite enabled, and Magento is 1.9.3.2, Portuguese translated (no idea if that makes any difference).

/api/rest returns:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/">
  <SOAP-ENV:Body>
    <SOAP-ENV:Fault>
      <faultcode>Sender</faultcode>
      <faultstring>Invalid XML</faultstring>
    </SOAP-ENV:Fault>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

but /api.php?type=rest returns:

<magento_api>
<messages>
  <error>
    <data_item>
      <code>404</code>
      <message>Request does not match type route.</message>
    </data_item>
  </error>
</messages>
</magento_api>
