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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// Implements the following CURL command:

// 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" \
// -H "Accept: application/vnd.api+json" \
// -H "Ibanity-Idempotency-Key: 94c5586e-e15e-4bae-a1fe-fdbefe1f11d3"  \
// -d grant_type=refresh_token \
// -d refresh_token=valid_refresh_token \
// -d client_id=valid_client_id \
// -d client_secret=valid_client_secret

// Ibanity provides the certificate + private key in PFX format.  This example will use the .pfx instead of the pair of PEM files.
// (It is also possible to implement using Chilkat with the PEM files, but PFX is easier.)
