Authorisation error with sparkpost when sending mails with their api

I'm trying to send emails from netlify functions with the api from sparkpost. But when I'm testing the function with functions:invoke verify-email --no-identity I get only a 401 error

I have this simple function

const SparkPost = require('sparkpost')
const client = new SparkPost(process.env.SPARKPOST)
const key = process.env.SPARKPOST
const handler = async(event, context, callback) => {
  console.log(key) //outputs the key, so this is not the problem
  return client.transmissions.send({
    options: {
      sandbox: true
    },
    content: {
      from: 'testing@sparkpostbox.com',
      subject: 'Hello, World!',
      html:'<html><body><p>Testing SparkPost - the world\'s most awesomest email service!</p></body></html>'
    },
    recipients: [
      {address: 'email@gmail.com'}
    ]
  })
  .then(data => {
    console.log('Woohoo! You just sent your first mailing!');
    console.log(data);
    return data
  })
  .catch(err => {
    console.log('Whoops! Something went wrong');
    console.log(err);
    return err
  });
}

and this is the error message I get. I have already recreated the api-key but with the same result

Request from ::1: GET /.netlify/functions/verify-email

Solution

  • There is likely one of two problems going on here.

    1. Make sure your API key has transmission read/write enabled here https://app.sparkpost.com/account/api-keys

    2. You are in the EU and trying to use the US server. In that case, you can do something like this:

    'host' => 'api.eu.sparkpost.com',

    or

    $httpClient = new GuzzleAdapter(new Client()); $sparky = new SparkPost($httpClient, ['key'=>'**********', 'host' => 'api.eu.sparkpost.com']);

    See some details here https://github.com/SparkPost/php-sparkpost/issues/180
