I have a REST API to callout from Salesforce.
The authorization of the API is through access token.
I am able to get the access token through POST request in Salesforce. Also tested from Postman through that token and able to get a successful response.
I am using the below code to callout the API using the access token:
String endpoint_x = '*****';//Putting my endpoint here
Http httpObject;
HttpResponse response;
String accessToken;
accessToken = MyUtilityClass.getAccessToken();
jsonBody = json.serializePretty('', true);//Yes, My JSON is empty
HttpRequest request = new HttpRequest();
request.setEndpoint(endpoint_x);
request.setHeader('Authorization', 'Bearer '+accessToken);
request.setMethod('POST');
request.setBody(jsonBody);
httpObject = new Http();
response = httpObject.send(request);
System.debug('Response=' + response);
Getting Response value as below:
System.HttpResponse[Status=Internal Server Error, StatusCode=500]
I have tried putting '{}' in the Jsonbody. Added 'Content-Type' in header but nothing worked.
Where should I lookout for this?
In the Postman, I was not putting anything in the body, and getting a successful response.
To get the same behaviour, I was using empty string in Apex, like this:
jsonBody = json.serializePretty('', true);
But the parser was not working correctly.
To solve this, I created a class without any field:
class ClassForEmptyBody{
}
And used object of that class in the serializer:
ClassForEmptyBody classForEmptyBodyObject = new ClassForEmptyBody();
jsonBody = json.serializePretty(classForEmptyBodyObject , true);
Why are you passing json body if nothing is in there. Just skip setbody code and try.

I've written multiple REST Endpoints in my Controller [GET, POST and PUT].
GET and POST calls are working fine. But when I try to hit PUT request from Postman, my java controller is not able to receive that request. There is no error message. Response body is empty. Response code in Postman is 200, OK.
Here is my PUT Endpoint which is not able to get request from Postman:
#PutMapping(value = "/devRegistration")
public Object deviceRegistration(HttpServletRequest httpRequest,
#RequestBody(required = false) Map<String, Object> jsonBody ){
ResponseEntity<Object> response = null;
System.out.println("jsonBody = "+jsonBody);
devService.deviceRegistration(httpRequest, jsonBody);
return response;
}
Here is my GET Endpoint which is working fine:
#GetMapping(value = "/checkRegistration")
public void checkRegistration(HttpServletRequest httpRequest,
#RequestParam("appId") String appId, #RequestParam("offset") String offset ){
Map<String, Object> jsonBody = new HashMap<String, Object>();
jsonBody.put("appId", appId);
jsonBody.put("offset", offset);
service.checkRegistration(httpRequest, jsonBody);
}
Postman URL with Headers and Body for PUT request is :
https://localhost:8443/api/device/devRegistration
In Body:
app_Id : some value
offset : some value
Headers are:
RequestHeader
Content-Type
Authorization
MobileHeader
SessionToken
But, System.out.println() is not being executed in PUT Endpoint.
Let me know, if any other info. is required.
I found the answer.
Actually, I need to pass the params in the Body as raw form instead of form-data in Postman.
It worked now.
Am getting the response of a request like this:
var response = command.PostCommand(testCommand);
I will like to validate that the response is in a json format so am doing it like this:
Assert.AreEqual("application/json", response.ContentType);
Is this way correctly or do i need to specifically validate it from the content-type header response?
You can use the IRestRequest.OnBeforeDeserialization callback to check the response content type before it gets deserialised:
var request = new RestRequest(url)
.AddQueryParameter(x, y); // whatever you need to configure
request.OnBeforeDeserialization =
response => CheckContentType(response.ContentType);
await client.PostAsync<MyResponse>(request);
I've been fiddling a POST request that isn't working. What I've found is that the content of the request is empty even though I believe I'm adding it correctly (even though there aren't any docs available that I can find).
var json = JsonConvert.SerializeObject(payload);
var client = new RestClient
{
Authority = "",
Credentials = OAuthCredentials.ForProtectedResource(Registration.ClientKey,
Registration.ClientSecret,
AuthorizationToken.Token,
AuthorizationToken.Secret),
Method = WebMethod.Post,
Path = url
};
var request = new RestRequest();
request.AddHeader("Accept", ContentType);
request.AddHeader("Content-Type", ContentType);
request.AddPostContent(Encoding.UTF8.GetBytes(json));
response = client.Request(request);
I'm not having any trouble with authorization. I just kept getting a 400 error. After capturing the request with Fiddler, I noticed that content-length was 0. What am I missing? Do I need to do something in addition to AddPostContent? When I check the request object right before executing, there is content in PostContent, but it's as if Hammock isn't adding it to the request. I am using the latest full nuget (not ClientProfile).
I am attempting to get eBay product IDs using the GetOffers request by sending it a product SKU.
My code is below, the problem I am currently having is that when I try to test this code is returns a 401 unauthorized. It's not returning any specific error code or anything descriptive.
I know my access token is valid I can't find any good examples on how to use this request.
public string getEbayOffers(string sku)
{
HttpResponseMessage response;
string accessToken = "tokenhere";
string param = Convert.ToBase64String(Encoding.ASCII.GetBytes(accessToken));
string url = $"sell/inventory/v1/offer?sku={sku}";
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://api.ebay.com/");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", param);
response = client.GetAsync(url).Result;
}
if (response.IsSuccessStatusCode)
{
return response.Content.ReadAsStringAsync().Result;
}
return null;
}
No need to convert your token to base64. The correct format should be "Bearer YOUR_USER_TOKEN". Replace YOUR_USER_TOKEN with your own token string.
Access token should be enough for getting offers but maybe you can try to use user token if above doesn't work.
I am trying to upload a video and encode it via azure rest service.
I have now hit the step of encoding the video but I am having difficulties with the request.
The following code shows my request:
var joburl = res.RequestMessage.RequestUri + "Jobs";
client = new HttpClient();
client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "Bearer " + token);
client.DefaultRequestHeaders.Add("x-ms-version", "2.8");
client.DefaultRequestHeaders.Add("DataServiceVersion", "3.0");
client.DefaultRequestHeaders.Add("MaxDataServiceVersion", "3.0");
client.DefaultRequestHeaders.Add("x-ms-date", date);
//accept
t = new NameValueHeaderValue("odata", "verbose");
type = new MediaTypeWithQualityHeaderValue("application/json");
type.Parameters.Add(t);
client.DefaultRequestHeaders.Accept.Add(type);
result = await client.PostAsync(joburl,json);
the url:https://wamsamsclus001rest-hs.cloudapp.net/api/Jobs
the json:
{"Name":"khgfiuydencodingjob","InputMediaAssets":[{"__metadata":{"Uri":"https://wamsamsclus001rest-hs.cloudapp.net/api/Assets('nb%3acid%3aUUID%3ad037b321-cd1c-43a9-9607-c4910fa7a85b')"}}],"Tasks":[{"Configuration":"H264 Adaptive Bitrate MP4 Set 720p","MediaProcessorId":"nb:mpid:UUID:1b1da727-93ae-4e46-a8a1-268828765609","TaskBody":"<?xml version=\"1.0\"encoding=\"utf-8\"?><taskBody><inputAsset>JobInputAsset(0)</inputAsset><outputAsset>JobOutputAsset(0)</outputAsset></taskBody>"}]}
The bearer token works as I use it for other request.
But I get a bad request 400 with the followin error message:
{"error":{"code":"","message":{"lang":"en-US","value":"Parsing request content failed due to: Make sure to only use property names that are defined by the type"}}}
Can anyone spot the error.
Thank you for the help
Okay I got it to work. Needed a odata=verbose in my json/string content - like this:
var jobInJson = JsonConvert.SerializeObject(job);
json = new StringContent(jobInJson, Encoding.UTF8);//,
json.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json;odata=verbose");
I tried this earlier however I got a error 500 but now it is working.
