(Xojo Plugin) Isabel Connect Create First Access Token and Refresh Token

See more Ibanity Examples

Creates your first access token and refresh token. Once created, the refresh token can be used to get a new access token after it expires, or before it expires.

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

Dim http As New 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: af621a8f-f74b-41a2-b011-336997633df4"  \
// -d grant_type=authorization_code \
// -d code=valid_authorization_code \
// -d client_id=valid_client_id \
// -d client_secret=valid_client_secret \
// -d redirect_uri=https://fake-tpp.com 

// 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.)
