Code snippets from the example app

    const handleCancel = async () => {
        try {
            await fetch(`${serverConfig.endpoint}/groups/AGENT/reservations/${reservationSid}/cancel`, {
                method: 'POST'
            });
            history.push(`/`);
        } catch (e) {
            console.log(e);
        }
    };

router.post('/:groupName/reservations/:reservationSid/cancel',
    async (req: Request, res: Response) => {
        const { groupName, reservationSid } = req.params;
        await streemApi.cancelReservation(streemConfig.companySid, groupName, reservationSid);
        res.json(await streemApi.getReservation(streemConfig.companySid, groupName, reservationSid));
    },
);

    async cancelReservation(
        companySid: string,
        groupName: string,
        reservationSid: string,
    ): Promise<void> {
        const url = `${this.baseUrl}/v1/companies/${companySid}/groups/${groupName}/reservations/${reservationSid}/cancel`;
        await axios.post<{ group_reservation: GroupReservation }>(url, {}, { ...this.config });
    }
