How to build an API that deletes an entry in Craft CMS

A flower that represents Craft CMS, beneath it sits the text "Delete Entry DELETE endpoint."

A step by step walkthrough in creating a DELETE RESTful endpoint in Craft CMS that uses a controller action to delete an existing entry.

The following tutorial walks you through how to use a Controller action to delete an existing Subscriber entry through a DELETE Craft CMS endpoint. The tutorial forms part of our Open Source series that details how to create API endpoints that manage the subscribers to the delasign website.

This tutorial assumes that you have created a channel called subscribers and that there are users for you to delete but we would like to note that the knowledge shared in this tutorial can be adapted to suit your needs.

We recommend downloading and setting up our Open Source Craft CMS starter project and checking out the main branch and carrying out the steps below. The changes carried out can be found on tutorial/delete-subscriber.

Step One: Create your API endpoint base

Please follow the tutorials linked below to create your RESTful API with an API key. We recommend testing it in Postman before continuing.

Please note that you must run this line after creating the API base for the API to register:

composer dump-autoload -a

Step Two: Complete the API

To complete the API you must first make sure that all the body parameters are present, then make sure that an entry with the details exists and finally, delete the entry.

A | Check that all the body parameters are present

Gather the body using the following line

$body = Craft::$app->request->getBodyParams();

Subsequently make sure that all the parameters are present and set them to variables that you can use later, through code similar to:

if (isset($body['YOUR_VARIABLE'])) { $YOUR_VARIABLE = $body['YOUR_VARIABLE']; } else { return $this->sendResponse(400,'Body is missing YOUR_VARIABLE variable.', null); }

Please note that if the variable doesn't exist we return a standardized bad request with an error stating that the variable is missing.

B | Make sure that an entry exists

In order for any Entry related code to be written, we must import the follow statement above your controller class

use craft\elements\Entry;

Subsequently, you must check that the subscriber exists. If it does not exist, you must respond with an error that the subscriber does not exists.

In our case we did this by checking that the count for subscriber entries whose email field matches the email in the request body is equal to 1.

C | Delete the entry

Finally, you must get the entry and delete it, using code similar to the one below.

The deleteElement function produces a boolean result that informs you if the deletion of the entry succeeded or not. Use that to give a 200 or a 400 API response, depending on whether it succeeded or failed.

Here is a sample Controller that gathers all the subscriber and returns them as a JSON.

Step Three: Test

Confirm that the API functions as expected by making a Postman call to your endpoint.
