Hello Stephen,
Really thanks for your quick reply!
Couple things to highlight
1) The cURL example seems not correct, '-X POST' is not included which in think by default is GET?
2) The command I ran has syntax issue, after '--insecure' it is missing '--form'
3) MyInputTextKey is mandatory
4) The command below works for me:
curl -X POST --user admin:password --insecure --form "file=@/c/Users/naichun/Downloads/layer7/OAuthSolutionKit-4.0.00-2339.sskar" https://10.10.1.251:9443/restman/1.0/solutionKitManagers --form MyInputTextKey=Hello
Regards,
Naichun
