Async/Await in Vue/Laravel

Im doing a CRUD for my Vue-Laravel aplication Im getting to the "/create" route and im creating a new "despesa" in my browser but when i press F5 doesnt save in my backend only in my frontend, how can i do that?

FRONTEND:

async addDespesa() {
  let uri = "api/despesas/create";
  const response = await axios.get(uri, this.despesa).then((response) => {
      this.despesas.push({
        des: this.despesa.des,
        valr: this.despesa.valr,
        stt: this.despesa.stt,
        vencc: this.despesa.vencc,
        emiss:this.despesa.emiss,
      });
       this.despesa.des = '';
      this.despesa.valr = '';
      this.despesa.vencc = '';
      this.despesa.stt = '';
      this.despesa.emiss = '';
      })

},

BACKEND:

public function create() {
//
}
