First, create a user and get an access token if you haven’t done that already. Then, you can record measurements for a user. The request should include the user’s access token in the Authorization header. There are examples of how to do this in any language in the measurement endpoint documentation. However, here is an example using javascript: 


async function postMeasurements(dfdaUser, measurements) {
  const response = await fetch(`https://safe.dfda.earth/api/v1/measurements`, {
    method: 'POST',
    headers: {
      'Content-type': 'application/json',
      'Authorization': `Bearer ${dfdaUser.accessToken}`
    },
    body: JSON.stringify({
      measurements
    })
  });
}
