Remove a card by index

DELETE /v1/pages/:pageId/blocks/:blockId/cards/:index

The required path index starts at zero; pass selector in query without @N. Bitrix24 without an index would remove the last card. Removal is permanent outside block history; removing the last card is allowed. A missing card returns 404 ENTITY_NOT_FOUND.

Requires the landing scope; READONLY keys receive 403 before mutation. Page-scoped actions check that the block belongs to the page.

Optional query scope: KNOWLEDGE, GROUP or MAINPAGE for that page context; omit for a regular site. IDs must be positive safe integers.

JavaScript — personal key

javascript

const response = await fetch("https://vibecode.bitrix24.com/v1/pages/42/blocks/50/cards/1?selector=.landing-block-card", {
  method: "DELETE",
  headers: {"X-Api-Key": "YOUR_API_KEY"},
})
const result = await response.json()
if (!response.ok) throw new Error(result.error.message)
console.log(result.data)

Response

JSON

{
  "success": true,
  "data": {
    "cards": {
      ".landing-block-card": [
        {
          "index": 0,
          "content": "<div class=\"landing-block-card\">Example</div>"
        }
      ]
    }
  }
}

A refusal after mutation does not undo the Bitrix24 action. On 422/502 after dispatch, read the block first; retrying clone/add can create another card.
