Converting Postman generated Curl to XBasic

[glenschild]

I have an api call successfully working in Postman but when I use the XBasic Curl genie I am getting an error which I cannot figure out.

The error message that is returned in the debugger

"{"error":"unsupported_grant_type","message":"The authorization grant type is not supported by the authorization server.","hint":"Check the `grant_type` parameter"}"

Yet from what I can see the parameter is correctly set.

Does anyone have any experience with this?

Hi Glen,
I've been working on more API's recently, but each one seems to have it's own rules.
More often than not, I find myself ignoring curl, and actually converting the curl command to xbasic.
It would be helpful to know more about the API, simply because of all the intricacies (Square really does some strange things).

This is the curl statement generated by postman (with pw details etc redacted)

curl --location --request POST 'https://appliveapi.dev.xxxxxx.co.uk/api/v1/token' --form 'grant_type="password"' --form 'client_id="1"' --form 'client_secret="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"' --form 'username="xxxxxxxxxxxxxxxxxxxxxxxxxxx"' --form 'scope="integration"' --form 'password="xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"'

Let me try this again.
I need information about the API you're trying to use.
The curl statement does not provide the API definition.

Hi
Here is some code i use , adapted to your needs. Lately i'm not using curl anymore, but rather http_fetch which gives more control.

dim fff as extension::CurlFile
myURL = "https://appliveapi.dev.xxxxxx.co.uk/api/v1/token"
vGrant = "grant_type=\"yourpassword\""
vClient = "client_id=1"
vSecret = "client_secret=\"xxxxxxxxx\""
vUser = "username=\"xxxxxxxx\""
vScope = "scope=\"integration\""
vPassword = "password=\"xxxxxxxx\""

vPostFields = vGrant+"&"+vClient+"&"+vSecret+"&"+vUser+"&"+vScope+"&"+vPassword

cf = extension::Curl.Init()
cf.setOpt("URL", myURL)
cf.setOpt("POSTFIELDS",vPostFields)
cf.setOpt("MAXREDIRS",50)
cf.SetOpt("CAINFO","C:\\Program Files (x86)\\a5V12\\CARoot\\ca-cert.pem")
cf.setOpt("CAPATH","C:\\Program Files (x86)\\a5V12\\CARoot")
cf.setOpt("CUSTOMREQUEST","POST")
cf.setOpt("TCP_KEEPALIVE",1)
cf.SetOpt("FILE",fff)
flag = cf.Exec()
if flag then
else
showvar("error: " + cf.Error() )
end if
