Azure function to LoginWithServerCustomId fails with bad request

I'm calling a custom Azure Function from Unity via UnityWebRequest that validates the player with Meta then logs in to PlayFab LoginWithServerCustomId API.

     [FunctionName("LogInViaOculus")]
     public static async Task<IActionResult> Run(
         [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
         ILogger log)
     {
         string reqBody = await req.ReadAsStringAsync();
         LoginArgs args = JsonConvert.DeserializeObject<LoginArgs>(reqBody);

         var client = new HttpClient();
    
         // Meta validation code redacted
    
         // bool createNew and string customId from form
    
     client.DefaultRequestHeaders.Add("X-SecretKey", "MYACTUALAPPSECRETCODEGOESHERE");
    
             var loginReqCont = new FormUrlEncodedContent(new[] {
                 new KeyValuePair&lt;string, string&gt;("CreateAccount", args.createNew.ToString()),
                 new KeyValuePair&lt;string, string&gt;("ServerCustomId", args.customId),
             });
    
             string loginUri = $"https://APPID.playfabapi.com/Server/LoginWithServerCustomId";
             HttpResponseMessage loginResponse = await client.PostAsync(
                 loginUri, loginReqCont);
    
             if (!loginResponse.IsSuccessStatusCode)
             {
                 log.LogError($"PlayFab Login Error {loginResponse.StatusCode}: {loginResponse.ReasonPhrase}");
                 return new BadRequestObjectResult($"PlayFab Login Error {loginResponse.StatusCode}: {loginResponse.ReasonPhrase}");
             }
    
             string loginResult = null;
             using (var reader = new StreamReader(await loginResponse.Content.ReadAsStreamAsync()))
             {
                 loginResult = await reader.ReadToEndAsync();
             }
    
             return new OkObjectResult(loginResult);

}

But this returns 400 Bad Request and no other data. Did I miss an authentication? Is there a wait to get more data out of this error?

PlayFab API accepts data in JSON format as the request body, so you may use the StringContent class to create a request body containing JSON data. Here is the code example:

 var client = new HttpClient();
        
             client.DefaultRequestHeaders.Add("X-SecretKey", "SecretKey");
                 
              var requestBody = new JObject
             {
                 ["ServerCustomId"] = "servercustomIdTest",
                 ["CreateAccount"] = true
             };
        
              var loginReqCont = new StringContent(requestBody.ToString(),Encoding.UTF8,"application/json");
        
              string loginUri = $https://TitleId.playfabapi.com/Server/LoginWithServerCustomId;
                 
              HttpResponseMessage loginResponse = await client.PostAsync(loginUri, loginReqCont);
        
              if (!loginResponse.IsSuccessStatusCode)
              {
                  log.LogError($"PlayFab Login Error {loginResponse.StatusCode}: {loginResponse.ReasonPhrase}");
                  return new BadRequestObjectResult($"PlayFab Login Error {loginResponse.StatusCode}: {loginResponse.ReasonPhrase}");
              }
        
              string loginResult = null;
              using (var reader = new StreamReader(await loginResponse.Content.ReadAsStreamAsync()))
              {
                  loginResult = await reader.ReadToEndAsync();
              }
        
              return new OkObjectResult(loginResult);

In addition, you may run “dotnet add package PlayFabAllSDK” to install the package to your AzureFunction project and call Login With Server CustomId API directly instead of make http request manually.

Thanks, I already had PlayFabAllSDK installed, I just forgot about checking it. Going that route is much cleaner and got me up and running.

I should note that I had very similar JavaScript code working on the Unity Gaming Services Cloudscript, the only difference is that I don’t have the Bearer authentication, but that was provided via UGS as far as I know. Do I need to (and how do I) get/pass the token from the client?
