How can I add "withCredentials:true" for HTTP requests generated by Swagger UI?

One way to solve this without customizing the Swagger UI is to deal with it on the server side. The following assumes that the swagger docs is served at /swagger relative path.

Middleware

/// <summary>
/// Middleware to protect API Swagger docs
/// </summary>
public class SwaggerAuthorizationMiddleware
{
    private readonly RequestDelegate _next;
    private readonly ILogger _logger;

    public SwaggerAuthorizationMiddleware(RequestDelegate next, ILogger<SwaggerAuthorizationMiddleware> logger)
    {
        _next = next;
        _logger = logger;
    }

    public async Task Invoke(HttpContext context)
    {
        // If API documentation route and user isn't authenticated or doesn't have the appropriate authorization, then block
        if (context.Request.Path.StartsWithSegments("/swagger") && !context.User.Identity.IsAuthenticated)
        {
            _logger.LogWarning($"API documentation endpoint unauthorized access attempt by [{context.Connection.RemoteIpAddress}]");
            context.Response.StatusCode = StatusCodes.Status401Unauthorized;
            return;
        }

        await _next.Invoke(context);
    }

Startup (in Configure method)

 app.UseAuthentication();
 app.UseAuthorization();

 app.UseMiddleware<SwaggerAuthorizationMiddleware>();
