Angular HTTPClient put and post wont work

I have multiple services in my Angular Ionic App all copys of each other with the slightest changes

I have a method like this (delete/update/get all work):

endpoint = 'https://localhost:7183/api/CheckinData';
httpOptions = {headers: new HttpHeaders({ 'content-Type': 'application/json' })};

clockIn(time, date)
  {
    const reply = new CheckinData();
    reply.userid = 2; //placeholder untill better authentication implementation
    reply.time = time;
    reply.date = date;
    this.create(reply);
  }

create(data: CheckinData): Observable<any>
  {
    console.log('clockin', this.endpoint, JSON.stringify(data));
    return this.http.post(this.endpoint, JSON.stringify(data), this.httpOptions)
      .pipe(catchError(this.handleError<CheckinData>('Error occured')));

  }

idk if its relevant but here is my CheckinData class

export class CheckinData
{
  id: number;
  time: Time;
  date: Date;
  userid: number;
}

Console log works with return (-> method gets called):
clockin https://localhost:7183/api/CheckinData {"userid":2,"time":"10 45 AM","date":"15 11 2022"}

There are no Errors

But when I call get/ check in SSMS there is no new Entry

For example this call works just fine (different service, different Api controller)

  create(todo: ToDo): Observable<any> {
    console.log('createToDo', this.endpoint, JSON.stringify(todo));
    return this.httpClient.post(this.endpoint, JSON.stringify(todo), this.httpOptions)
      .pipe(catchError(this.handleError<ToDo>('Error occured')));
  }

I can post with swagger/postman (-> api works)

I tried put instead of post and it doesn’t work either

-> there has to be another potential Mistake Iam Missing

If you have any Ideas what could be wrong/what else to check all Help is appreciated

>Solution :

From your code, I don’t see your front-end side will submit the request to API. You need to subscribe the Observable in order to submit the request.

clockIn(time, date) {
  ...

  this.create(reply)
    .subscribe(x => {
      // Action after receive response from API
    });
}
