Thank you for contacting support.

You may delete a bookmark using its title, or all bookmarks as explained in Add and Delete a Bookmark. If you still need any assistance then please share your sample PDF document as well.

Thanks,
But if i want delete particular bookmark it’s only on Title based, but if pdf contains 2 bookmarks with same Title name, and if want to delete 2nd position bookmarks then How?
ex; A1 > Bookmark Title name
A2 > Bookmark Title name
A1 >Bookmark Title name [ if i want to delete this] How?
From front end they only send Json Format with index position which is to be delete?

Please Explain How?
