"The Public Key is required."

[DovahBrownies]

Hi.

I'm trying to use the API endpoint to send a request and keep receiving a 400 with the message:

The Public Key is required. To find this ID, visit https://dashboard.emailjs.com/admin/account

I am providing a valid user_id in the body, as outlined in the docs. Could I be missing something?

I'm currently testing this in Postman.

Any help would be greatly appreciated!

Fetch Request Sample Code

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");

var requestOptions = {
    method: 'POST',
    headers: myHeaders,
    redirect: 'follow'
};

fetch("https://api.emailjs.com/api/v1.0/email/send?service_id=gmail_service&template_id=default_template&user_id=XXXXXX&template_params[to_name]=Jane Doe&template_params[from_name]=John Doe&template_params[from_email][email protected]&template_params[reply_to][email protected]&template_params[from_message]=Hello. I am John Doe.", requestOptions)
    .then(response => response.text())
    .then(result => console.log(result))
    .catch(error => console.log('error', error));

The params have to be in the body in JSON format instead of query params.

Still same error:

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");

var formdata = new FormData();
formdata.append("service_id", "gmail_service");
formdata.append("template_id", "default_template");
formdata.append("user_id", "XXXXX");
formdata.append("template_params[to_name]", "Jane Doe");
formdata.append("template_params[from_name]", "John Doe");
formdata.append("template_params[from_email]", "[email protected]");
formdata.append("template_params[reply_to]", "[email protected]");
formdata.append("template_params[from_message]", "Hello. I am John Doe.");

var requestOptions = {
		method: 'POST',
		headers: myHeaders,
		body: formdata,
		redirect: 'follow'
};

fetch("https://api.emailjs.com/api/v1.0/email/send", requestOptions)
		.then(response => response.text())
		.then(result => console.log(result))
		.catch(error => console.log('error', error));

But I have resolved the issue.
I was making the call on the app's server side. This required me to do the following:

• Enable "Allow EmailJS API for non-browser applications"
• Pass the account private key in an accessToken parameter.

Thank you very much!
