Simple asynchronous wrapper for the Sell.App API, using the reqwest crate under the hood.
use sellapp;
use serde_json::{self, Value};
use tokio;
#[tokio::main]
async fn main() {
let api = sellapp::init("your_api_key", "");
let res = api.invoices_list_all("?limit=25").await.unwrap();
let text = res.text().await;
let data: Value = serde_json::from_str(&text.unwrap()).unwrap();
println!("The ID of the 4th invoice is: {}", data["data"][3]["id"]);
}
