Answer 1

As the article you provided, you need to use _master key under Manage and Host key

Answer 2

I use the following class in my integration tests against service bus triggered Azure Functions.
class AzureFunctionCaller
{
private readonly HttpClient _httpClient;
private readonly string _functionUri;
public AzureFunctionCaller(string functionName)
{
_httpClient = new HttpClient();
_httpClient.DefaultRequestHeaders.Add("x-functions-key","<Key>");
_functionUri = $"<FUNCTION_ENDPOINT>/admin/functions/{functionName}";
}
public async Task CallViaAdminEndpoint(string content)
{
var httpContent = new StringContent(content, Encoding.UTF8, "application/json");
var response = await _httpClient.PostAsync(_functionUri, httpContent);
var responseContent = await response.Content.ReadAsStringAsync();
Console.WriteLine($"Response content: {responseContent}");
}
}
Then you must send the data in a format where you place the content in "input" object.
var azureFunctionCaller = new AzureFunctionCaller("<FunctionName>");
var obj = new
{
... // properties you want to send
};
var jsonContent = JsonConvert.SerializeObject(new
{
input = JsonConvert.SerializeObject(obj)
});
await azureFunctionCaller.CallViaAdminEndpoint(jsonContent);`
To explain the input property, here is how the same call looks like in postman:
