Error code 415 : Unsupported Media Type' - occures when: using API to cancel Paypal subscription

[PeterKhaled]

Dear Community,

I have spent the whole day trying to cancel a Paypal subscription by code. All the time I keep geting the response: Error 415 Unsupported Media Type. I have turned google up and down to find a solution, uselessly. I am using the follwoing C#.Net code:

string url = "https://api-m.paypal.com/v1/billing/subscriptions/" + subscription_ID + "/cancel";

var client = new HttpClient();
var msg = new HttpRequestMessage(HttpMethod.Post, url);
msg.Headers.Authorization = new AuthenticationHeaderValue("Bearer", txt.Text);
msg.Content = new StringContent(JsonConvert.SerializeObject("reason: Item out of stock"));// I have tried either the not using of this convert uselessly
var response = client.SendAsync(msg).Result;

---

Kindly, what to do ?

Thanks,

Peter

Hi @PeterKhaled 

Thank you for posting to the PayPal Community.

I noticed in your request new AuthenticationHeaderValue("Bearer", txt.Text);

This file type: txt.Text is most likely causing the 415 error message. Our server will not recognize a .txt file, so if you are writing your bearer token to a .txt file, it will not be read by the PayPal server. Please pass your token in the request, not as a file. 

Thank you,

Jennifer

Dear Jennifer, Sorry i did not clarify this part. The txt.text, which I used, represents a string type (of a Textbox), not a file. Please note, it is successful when i apply my data directly by the postman. However, it fails by the .net code. Regards Peter
