Check if the email template really exists in SendGrid before sending the email

I am trying to send emails using SendGrid email service using Dynamic Templates.

I am using SendGrid version 7.2.

"sendgrid/sendgrid": "^7.2",

Sending emails is working great and I am able to send emails successfully using the below code.

$this->mail->setTemplateId($templateId);
$response = $this->sendGrid->send($this->mail);

if ($response->statusCode() != 202) {
    throw new \Exception("Failed to Send Email.");
}

The problem is sometimes the $templateId can be an invalid or belong to a deleted template.

I looked through the internet for hours and searched the documentation but couldn't find anything.

Is there a way to check if the email template exists before trying to send the email? Or maybe to retrieve a list of active email template ids from SendGrid?

You can use the "Retrieve paged transactional templates" API to get all (dynamic) templates to check if there is one that matches your ID.

<?php
// Uncomment next line if you're not using a dependency loader (such as Composer)
// require_once '<PATH TO>/sendgrid-php.php';

$apiKey = getenv('SENDGRID_API_KEY');
$sg = new \SendGrid($apiKey);
$query_params = json_decode('{
    "generations": "legacy",
    "page_size": 18
}');

try {
    $response = $sg->client->templates()->get(null, $query_params);
    print $response->statusCode() . "\n";
    print_r($response->headers());
    print $response->body() . "\n";
} catch (Exception $ex) {
    echo 'Caught exception: '.  $ex->getMessage();
}

or via cURL

curl -G -X GET https://api.sendgrid.com/v3/templates \
--header "Authorization: Bearer <<YOUR_API_KEY_HERE>>" \
--data-urlencode "generations=dynamic" \
--data-urlencode "page_size=18"
