Using Sendgrid API from C# throwing an error "UnAuthrized" and "Http verb GET does not support body"

[ops-mamdouh]

Hi There,

I am trying to get the Bounces from Sendgrid, I followed below two documentations:

• https://docs.sendgrid.com/api-reference/bounces-api/retrieve-all-bounces
• https://sendgrid.api-docs.io/v3.0/bounces-api/retrieve-all-bounces

Testing the API using "try it" on doc site works. but using the same code from your site doesn't

Not sure what I am missing, I spoke to support agent, he tried till reached his limit and advised to open ticket here.

Here is snippet of my code

Here are the errors form both code samples:

Here is the values from Debug mode:

Thanks,

It worked with me by removing this line: request.AddParameter("application/json", "{}", ParameterType.RequestBody);

Full working code: var client = new RestClient("https://api.sendgrid.com/v3/suppression/bounces"); var request = new RestRequest(Method.GET); request.AddHeader("content-type", "application/json"); request.AddHeader("accept", "application/json"); request.AddHeader("authorization", SendGridAPIKey); IRestResponse response = client.Execute(request);
