Hi,
I am currently trying to implement a new secure credit card payment system, YOCO
It's a 2 step process, initiated by a POST, with the bearer security, amount, currency and then on the success of the POST,
one of the return data fields is a redirect URL ,
which I must direct the user to.
This redirected URL is a page on the providor site, where the user will enter CC, Expiry etc,
on success/fail/cancel , one of my URL will be called
Question is how to handle the re-direct after the receipt of the successful POST?
TIA for any info

Hi,
Plan I'm going with, if I missing the obvious let me know.
Memory NetWebform
In the generate form , call a hidden NetWebClient procedure that handles the POST and return URL to NetWebForm
On the NetWebform, display fields for confirmation and a PAY button with the URL returned by the NetWebClient
If client clicks the button, then they will redirected to the CC Payment page
If there are other ways to handle this, please let me know

is the correct way, this is an example for the old Stripe API, the new API is a little more difficult, but the Yoco API is similar to the old Stripe API, you can convert this code to NT curl and avoid using NetWebClient. By the way, I never used nt curl but I think it's similar to Mike Duglas' curl
SendRequest ROUTINE
DATA
curl TCurlHttpClass
res CURLcode
qIndex LONG, AUTO
respBuffer STRING(65000) !big enuff to hold received response
CODE
curl.Init()
curl.FreeHttpHeaders()
SSLInfo:bUseSSL = TRUE
p_web.ssv('PaymentFrom','Afiliacion')
IF SSLInfo:bUseSSL
res = curl.SetSSLVerifyHost(SSLInfo:bVerifyHost)
IF res <> CURLE_OK
END
res = curl.SetSSLVerifyPeer(SSLInfo:bVerifyPeer)
IF res <> CURLE_OK
END
res = curl.SetSSLVersion(SSLInfo:Version)
IF res <> CURLE_OK
END
IF SSLInfo:Certificate
res = curl.SetCAInfo(SSLInfo:Certificate)
IF res <> CURLE_OK
END
END
END
curl.SetCustomRequest('POST')
!-H "Content-Type: application/json"
!-H "Authorization: Bearer Access-Token"
CASE p_Web.gsv('Com:PaymentEnviroment')
OF 'sandbox'
curl.AddHttpHeader('Authorization: Bearer '&p_web.gsv('Com:StripteSandBoxToken'))
OF 'production'
curl.AddHttpHeader('Authorization: Bearer '&p_web.gsv('Com:StripteProductionToken'))
END
!-- applies http headers added by AddHttpHeader calls
curl.SetHttpHeaders()
!----Create a Token --------!
Send:Url = 'https://api.stripe.com/v1/tokens'
Send:PostParams ='card[number]='&p_web.gsv('CardNumber')&'&card[exp_month]='&p_web.GSV('ExpMonth')&'&card[exp_year]='&p_web.GSV('ExpYear')&'&card[cvc]='&p_web.GSV('Cvv')
!----Create a Token -------!
CLEAR(TokenError)
CLEAR(Token)
res = curl.SendRequestStr(Send:Url, Send:PostParams, respBuffer)

JohanR,
I would call the NtWebClient before the memory form call, if you call it in the generate form it will be called many times.
And you can use a media field in the memory form to include the CC form (using its url) in your page.
Hope this helps

This is the approach I would adopt, and indeed the approach I think they recommend.
