Prerequisites for sending your first email with the Emailkick API

Before you can start using the API, you need to do the following:

Create a Emailkick account.
Create an API Key and Access ID.

Sending using API

Your API call must have the following components:

A host. The host for emailkick is https://api.emailkick.com/mail/send
Request method set to POST
A request payload. the email payload is a structured JSON which has data like to, from, templateId and the authorization keys.

A NodeJS function request using fetch looks like this


const fetch = require('node-fetch');

function sendEmail({ templateId, variables, to, from }) {
    const APIKEY = "<<YOUR EMAILKICK API KEY>>";
    const ACCESSID = "<<YOUR EMAILKICK ACCESS ID>>";

    var raw = JSON.stringify({
        "APIKEY": APIKEY,
        "ACCESSID": ACCESSID,
        "to": to,
        "from": from,
        "templateId": templateId,
        "variables": variables
    });

    var requestOptions = {
        method: 'POST',
        headers: {
            "Content-Type", "application/json"
        },
        body: raw,
    };

    fetch("https://api.emailkick.be/mail/send/", requestOptions)
    .then(response => response.json())
    .then(result => {
        //do some action
        console.log(result);
    })
    .catch(error => console.log('error', error));

}


sendEmail({
    to: 'elon@emailkick.com',
    from: 'yourname@yourdomain.com',
    templateId: '<<Emailkick Template Id>>'
});
