where can find the 'post ID' ??

Hello,

Go to Posts in your WordPress admin, and click the post you need the ID of. Then, if you look in the address bar of your browser, you’ll see something like this:

https://example.com/wp-admin/post.php?post=1280&action=edit

The number, in this case 1280, is the post ID.

this is very simple login ti your worpress site than go to the post copy the lijnk of post than open it in new tob in podt linkj u will find a numbers which loks like this

post=1234

in this 1234 is your post id.

How do I find an id?

Thanks a lot ! thats really helpful !
