App Script - Alternative to using UrlFetchApp

Question

Good afternoon

Trying to access API

https://developer-portal.driver-vehicle-licensing.api.gov.uk/apis/vehicle-enquiry-service/code-examples.html#ves-api-code-examples

from App Script

Have accessed other API's in the past & used UrlFetchApp, but does not seem to be supported by this API

Not sure how to use one of the other options

Thanks Simon

I believe your goal is as follows.

• From your provided official document, you want to convert the following curl command to Google Apps Script.

  curl --location --request POST 'https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles' \
  --header 'x-api-key: REPLACE WITH YOUR API KEY' \
  --header 'Content-Type: application/json' \
  --data '{"registrationNumber": "AA19AAA"}'
  

• You have already confirmed that the above curl command worked fine.

In this case, how about the following sample script?

Sample script:

function myFunction() {
  const url = "https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles";
  const data = { "registrationNumber": "AA19AAA" };
  const res = UrlFetchApp.fetch(url, {
    method: "post",
    headers: { "x-api-key": "REPLACE WITH YOUR API KEY" },
    contentType: "application/json",
    payload: JSON.stringify(data)
  });
  console.log(res.getContentText());
}

Note:

• In this sample, it supposes that you have already confirmed that the sample curl command works fine with your values. Please be careful about this.

Reference:

• fetch(url, params)
