(JavaScript) Isabel Connect Create Access Token given Valid Refresh Token

See more Ibanity Examples

For more information, see https://documentation.ibanity.com/isabel-connect/api#create-access-token

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var http = new CkHttp();

// 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.)

    return;
}

// "valid_client_id", and "valid_client_secret".
// For the live app, you would replace these with actual values.

// Sample JSON response:
// (Sample code for parsing the JSON response is shown below)

// Notice that we don't get a new refresh token.  The original refresh token is used each time we

// until we need to refresh again.
