Sending data to my topic via Rest API


I’m trying to get data from my Topic via my API client, but I’m receiving an “Invalid Route” response.

Here is my “Get” verb request:

Please advise.

Thank you,

Hi there! I just want to confirm what you’re trying to do here. The title of your post says “sending data to the topic” which implies you want a producer. But the body of the post suggests you want to get data from the topic, which implies a consumer.

Please clarify so we can advise! Thanks!

Hi Danica,
Sorry for the confusion.

I actually want to do both. I want to first send the data in a Post request and then retreive the data in a Get request.


Okay, it seems like I’m getting closer to successfully Producing Data to my Topic, but now I’m getting error code 200:
“error_code”: 200,
“cluster_id”: “lkc-57rvon”,
“topic_name”: “ccc_topic_0”,
“partition_id”: 5,
“offset”: 0,
“timestamp”: “2022-10-15T12:40:03.949Z”,
“value”: {
“type”: “JSON”,
“size”: 12

Here’s my Rest Client:

var client = new RestClient(“”);

client.Timeout = -1;

var request = new RestRequest(Method.POST);

request.AddHeader(“Authorization”, “Basic NVYyVlE3R003N09TUE1WUzpqRmUzSmxEUmNJd0tuc052QS9KSGgrUzJDcE1uTk91alJzZVBJSStGL0VxRWl2RFMzYjJldUZWNjIzWVlZNmVm”);

request.AddHeader(“Content-Type”, “application/json”);

var body = @“{”“value”“: {”“type”“: ““JSON””, ““data””: ““Hello Ken!””}}”;

request.AddParameter(“application/json”, body, ParameterType.RequestBody);

IRestResponse response = client.Execute(request);


Okay, I’m able to successfully send data to the topic using my Rest API client.

Can you please provide me an example demonstrating how to retreive data from my topic using a Rest API client.

It appears you are using C#? Why not use KafkaConsumer directly?
