Problems sending post requests

[swoop]

Good day! I have an Angular app. I send a post request for

https://api.hubapi.com/deals/v1/deal?hapikey=MY_API_KEY

and get an error

OPTIONS https://api.hubapi.com/deals/v1/deal?hapikey=my-key 401

Access to XMLHttpRequest at 'https://api.hubapi.com/deals/v1/deal?hapikey=!!!!!!!!!!!' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Tell me what's wrong please. That is my code

export class CrmService {
  private readonly key = 'my api-key';
  private readonly API_URL = 'https://api.hubapi.com/';
  private readonly DEAL_URL = `${this.API_URL}deals/v1/deal?hapikey=${this.key}`;

  constructor(private http: HttpClient) {}

  private get headers() {
    return new HttpHeaders({'Content-Type': 'application/json'});
  }

  sendOrder(param) {
    const url = this.DEAL_URL;
    const params = {
      'properties': [
        {
          'value': `${param.name} ${param.surname}`,
          'name': 'dealname'
        },
        {
          'value': `${param.cost}`,
          'name': 'amount'
        },
        {
          'value': `${param.tel}`,
          'name': 'telnumber'
        },
        {
          'value': `${param.recipient}`,
          'name': 'email'
        },
        {
          'value': 'was deleted!!',
          'name': 'hubspot_owner_id'
        },
        {
          'value': `${param.model} ${param.memory} ${param.condition}`,
          'name': 'old'
        },
        {
          'value': `${param.tradeinModel} ${param.tradeinMemory} ${param.tradeinColor}`,
          'name': 'new'
        },
        {
          'value': `${param.comment}`,
          'name': 'comment'
        },
        {
          'value': `${param.address}`,
          'name': 'adress'
        },
        {
          'value': `${param.day} ${param.time}`,
          'name': 'time'
        }
      ]
    };
    return this.http.post(url, params, {headers: this.headers});
  }
