(Visual FoxPro) 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.

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

* 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 CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('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.)
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Cert')
loCert = CreateObject('Chilkat.Cert')
lnSuccess = loCert.LoadPfxFile("qa_data/pfx/my_ibanity_certificate.pfx","my_pfx_password")
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loHttp
    RELEASE loCert
    CANCEL
ENDIF

lnSuccess = loHttp.SetSslClientCert(loCert)
IF (lnSuccess = 0) THEN

ENDIF

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.HttpRequest')

loReq.Path = "/isabel-connect/oauth2/token"
loReq.ContentType = "application/x-www-form-urlencoded"
loReq.AddParam("grant_type","authorization_code")

* Note: For sandbox testing, we literally want to use the strings
* "valid_authorization_code", "valid_client_id", and "valid_client_secret".
* For the live app, you would replace these with actual values.
loReq.AddParam("code","valid_authorization_code")
loReq.AddParam("client_id","valid_client_id")
loReq.AddParam("client_secret","valid_client_secret")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponseBody = CreateObject('Chilkat.StringBuilder')
loResp.GetBodySb(loSbResponseBody)
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')

* {
*   "token_type": "Bearer",

*   "expires_in": 1799,
*   "access_token": "access_token_1617371230"

lcToken_type = loJResp.StringOf("token_type")

lnExpires_in = loJResp.IntOf("expires_in")
lcAccess_token = loJResp.StringOf("access_token")

* Save to a file for future use in refreshing the access token.
* The refresh token is the same each time we refresh to get a new access token.
lnSuccess = loJResp.WriteFile("qa_data/tokens/isabel_refresh_token.json")

* Also save to a file to be used as the current access token.
