Sending json data to WebAPI .Net Core

🌱 Just Getting Started
1

I’ve created a request as follows:

2019-04-17_14-36-50
2019-04-17_14-36-501096×632 51.7 KB

You can see the error:

“{”“:[“Unexpected character encountered while parsing value: {. Path ‘’, line 1, position 1.”]}”.

The API is not being called.

I can’t see where I am going wrong. I’ve tested a separate method using form data without a problem.

GET /api/paypal/getorder HTTP/1.1
Host: localhost:52519
Content-Type: application/json
cache-control: no-cache
Postman-Token: 2eaf198a-c69c-4146-92e3-98ddc94892c1
{
  "orderID" : "123456789"

Hey @glenh,

Would you be able to explain a bit more about the implementation of the API?

It’s tricky to know what’s going on when you can only see one side of the problem :slight_smile:

It looks like you’re sending a JSON body with a GET request, is this how that endpoint accepts incoming requests?

Do you have any logging within the API code to see what’s happening when the request is made from Postman?

Your assumption that its Get then you are correct.

The request itself never gets to the method so logging is not called.

I will post the api method/code as soon as I can.

I really appreciate your reply and assistance.

The formatting of the request body was incorrect.
