我需要调用一个包含大量记录的api1，每个记录都有personId。 我需要在数据表中登记数据。根据personId，我必须从另一个api2中获取personName，并同时显示在同一数据表中。

here is my Service file contains two methods.

  return this.http.get(`${this.api1}`);
}
getcardStatus(id){
  return this.http.get(`${this.api2}/${id}`);
}


in the component ts file i need to implement method which can call both tha apis at same time to get required data.

i tried this but its not working.

listAllDisputes() {
  this.disputeService.getcardStatus().pipe(map( (res) =>{
    this.disputeslist = res;
    const id = this.disputeslist.card_id;
    return this.disputeService.listDisputes()
    }).subscribe( data =>{
      this.disputeslist = data;
    }));
}
