Is there an API call where you can get all achievements and all unread achievements?

Like this:

Update

Thanks to the answer of Glorfindel, I use the following methods to calculate the unread achievements.

Note: I'm using angular 8

notification.service.ts

public getAchievements(options?: IQuestionOptions): Observable<IResponse> {   
  const headers = new HttpHeaders()
    .set('Accept', '*/*');

  const params = new HttpParams()
    .set('key', {{APP_KEY}})
    .set('access_token', {{TOKEN}})
    .set('pageSize', '30')
    .set('page', '1')
    .set('filter', 'O5lYbEN2lExNfdp2Q');

  return this.http
    .get<IResponse>(
      'https://api.stackexchange.com/2.3/', 
      { headers, params }
    );
}

Counting unread items

public countUnread(items: any): number {
  if (!items) {
    return 0;
  }

  return items
    .map(item => item.is_unread ?
      item.reputation_change ?
        item.reputation_change
        : 1
      : 0)
    .reduce((accumulator, currentValue) => accumulator + currentValue);
}

Also to be mentioned is that this method is used for counting unread messages and unread achievements, depending on what was handed over.

  • I also came across this question but this has not been answered for over 5 years. And is there a way to figure out how / where the 'Stack Exchange mobile apps' get the value for changed reputations? – Norbert Bartko Nov 22 at 14:39
  • I found the API method and from my tests you should be able to make it work. More details are in the linked question. – Glorfindel Nov 22 at 18:31
