We are using .NET to access the batch screening api.
The below code returns Access Denied.
var batchesResponse = await batchWebServiceClient.createInitialAsync(batchRequest);
assigneeIdentifier = "cnu_so_162",
batchNames = batchNames, // - array of batchName
groupIdentifier = “cng_so_120”,
name = "",
ownerIdentifier = "cnu_so_162"
You are using the incorrect userIndentifier and groupIdentifier for your login account.
Your login account (firstname.lastname@example.org) has your userIdentifier - cnu_so_1xx and the group your userIndentifier has permissions to is groupIdentifier - cng_so_2xx
Note the difference between group vs user identifiers, (i.e. cng vs cnu)
Hope this helps,
