Hi BenCrowe, thank you very much for the reply. I'm using C# / console app, and I keep getting the same error you got "Could not match JWT signature to any of the bindings" when I try to get the access token after generating the JWT per the below and posting. I'm certain I have the right key. Below is what I have. Thanks again for any tips, much appreciated!
using Microsoft.IdentityModel.Tokens;
using RestSharp;
using System;
using System.IdentityModel.Tokens.Jwt;
using System.Linq;
using System.Text
string key = System.IO.File.ReadAllText(@"C:\[directory....]\private.key");
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
var credentials = new SigningCredentials
(securityKey, SecurityAlgorithms.HmacSha256Signature);
var header = new JwtHeader(credentials);
var payload = new JwtPayload
{ // payload stuff - double checked - values correct
{"exp",'....''},
{ "iss",",,,,,,"},
{"sub","......."},
{"https://.........",true},
{"aud","......."}
};
var secToken = new JwtSecurityToken(header, payload);
var handler = new JwtSecurityTokenHandler();
var tokenString = handler.WriteToken(secToken);
Console.WriteLine(tokenString);
Console.WriteLine("Consume Token");
var token = handler.ReadJwtToken(tokenString);
Console.WriteLine(token.Payload.First().Value);
