Diamond API v3

This example shows authentification flow and simple requests to Cutwise API. In the following piece of code you could see Promise chain resolved with cutShape of the first diamond in vendor inventory. You can get additional information here:

• Cutwise API Authentification
• Constants API
• Diamonds API V3

const USERNAME = ''; // Cutwise user login, requests will be authentificated as provided user
const PASSWORD = ''; // Cutwise user password
const CLIENT_ID = ''; // Client Application ID
const CLIENT_SECRET = ''; // Client Application Secret

(async () => {
  const authResp = await fetch(`https://cutwise.com/api/oauth/v2/token?grant_type=password&username=${USERNAME}&password=${PASSWORD}&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}`);
  const authRespAsJSON = await authResp.json();

  if (!authResp.ok) {
    console.error(authRespAsJSON.error);
    return;
  }

  const accessToken = authRespAsJSON.access_token;
  const requestParams = {
    headers: {
      Authorization: `Bearer ${accessToken}`,
      'Content-Type': 'application/json',
    },
  };

  const constantsPromise = fetch('https://api.cutwise.com/v2/constants/web', requestParams);
  const diamondsPromise = fetch('https://api.cutwise.com/v3/diamond?limit=8&offset=0', requestParams);

  const [constantsResp, diamondsResp] = await Promise.all([constantsPromise, diamondsPromise]);
  const constantsRespAsJSON = await constantsResp.json();
  const diamondsRespAsJSON = await diamondsResp.json();

  if (!constantsResp.ok) {
    console.error(constantsRespAsJSON.error);
    return;
  }

  if (!diamondsResp.ok) {
    console.error(diamondsRespAsJSON.error);
    return;
  }

  diamondsRespAsJSON.forEach((diamond) => {
    if (!diamond.cutShape) {
      return;
    }

    const cutShape = constantsRespAsJSON.dict.cutShape.find(cs => cs.id === diamond.cutShape);

    if (!cutShape) {
      return;
    }

    console.log(cutShape);
  });
})();

Diamond API v4

• Cutwise API Authentification
• Diamonds API V4
• Certifications API V4

const USERNAME = ''; // Cutwise user login, requests will be authentificated as provided user
const PASSWORD = ''; // Cutwise user password
const CLIENT_ID = ''; // Client Application ID
const CLIENT_SECRET = ''; // Client Application Secret

(async () => {
  const authRes = await fetch(`https://cutwise.com/api/oauth/v2/token?grant_type=password&username=${USERNAME}&password=${PASSWORD}&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}`);
  const authRespAsJSON = await authRes.json();

  if (!authRes.ok) {
    console.error(authRespAsJSON.error);
    return;
  }

  const accessToken = authRespAsJSON.access_token;
  const requestHeaders = {
    'Content-Type': 'application/json',
    Authorization: `Bearer ${accessToken}`,
  };

  const diamondResp = await fetch('https://api.cutwise.com/v4/diamond', {
    method: 'POST',
    body: JSON.stringify({
      sku: 'testqq',
      carat: 3.01,
      price: 300.0,
      isColored: false,
      isLabGrown: false,
      cutShape: 'Princess',
      clarity: 'IF',
      cutQuality: 'Fair',
    }),
    headers: requestHeaders,
  });

  const diamondAsJSON = await diamondResp.json();

  if (!diamondResp.ok) {
    console.error(diamondAsJSON.error[0]);
    return;
  }

  const certificationCreateResp = await fetch('https://api.cutwise.com/v4/certification', {
    method: 'POST',
    body: JSON.stringify({
      laboratory: 'GCAL',
      number: '33188',
      product: diamondResp.id,
    }),
    headers: requestHeaders,
  });

  const certificationCreateRespAsJSON = await certificationCreateResp.json();

  if (!certificationCreateResp.ok) {
    console.error(certificationCreateRespAsJSON.error[0]);
    return;
  }

  console.log(`Certification with id ${certificationCreateRespAsJSON.id} has been created and linked to the diamond`);
})();
