// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// curl -X POST https://api.ibanity.com/isabel-connect/oauth2/token \
// --cert certificate.pem:qwertyuiop1 \
// --key private_key.pem  \
// -H "Content-Type: application/x-www-form-urlencoded" \
