How to add Asklet to Drupal

Show Asklet under every Drupal article with a custom block - no module needed.

Steps

01
Copy your snippet

In Asklet, open your website and click Copy website snippet at the top.
02
Create a custom block

Add a basic block (Content → Blocks in Drupal 10.1 and later, Structure → Block layout → Custom block library before that). Set the body's text format to Full HTML, switch to Source and paste the snippet.
03
Place it below the content

In Structure → Block layout, place the block in the region under the main content. Under Visibility → Content type, tick Article so it only shows on articles.
04
Check it on your live site

Open a published article on a domain you listed in Asklet and answer the survey. To keep your own test answers out of the results, add the page in Asklet first: new pages start in test mode.

Your snippet looks like this

<iframe src="https://asklet.io/embed/s/<your-site>" title="Article feedback" width="100%" height="480" loading="lazy" referrerpolicy="unsafe-url" style="border:0"></iframe>

Keep referrerpolicy="unsafe-url" on the iframe - Asklet uses it to know which page the reader is on, so the right survey appears.
Basic HTML and Restricted HTML remove iframes. Use Full HTML, which only trusted roles should be allowed to use.
With Pathauto, articles get addresses such as /articles/my-article, so /articles/* covers them all.
