Update Cards in landing.block.updateCards

Choose a tool for developing with an AI agent:

use Alaio Vibecode to build an app for Bitrix24 from a task description without knowing any programming language. The agent writes the code and deploys the app to a server, with no manual hosting setup
use the MCP server to develop a REST API integration in your own project. The agent refers to the official REST documentation

Scope: landing

Who can execute the method: a user with "edit" access permission for the site

The method landing.block.updateCards updates a set of cards in a block and the nodes within those cards in the draft of the page.

This method works with cards described in the cards key of the block manifest. If the page is already published, changes will be visible to visitors after publication through the interface or by using the landing.landing.publication method.

Method Parameters

Required parameters are marked with *

Name `type`	Description
scope `string`	Internal scope of landings. It is not related to the REST scope `landing` in the method name. The value of `scope` must correspond to the type of site (detailed description)
lid* `integer`	Identifier of the page. The page identifier can be obtained using the landing.landing.getlist method
block* `integer`	Identifier of the block in the draft of the page. The block identifier can be obtained using the landing.block.getlist method with the parameter `params.edit_mode = 1`
data* `object`	Set of changes for the block cards (detailed description)

Parameter data

Key
type

Description

object

Card selector from the cards section of the block manifest.

The value describes the final set of cards for this selector and the changes to their nodes (detailed description).

To find available card selectors and presets for a specific block, retrieve the manifest using the landing.block.getmanifest method

Object

Name `type`	Description
source `array`	Defines the final order and number of cards (detailed description)
values `array`	Updates nodes within cards after applying `source` (detailed description)

Element of the source array

Name
type

Description

type
string

Type of the card source.

Possible values:
card - take the current card by index,
preset - create a card from a preset in manifest.cards.<selector>.presets.

Default - card

value
integer | string

Value of the card source.

For card, this is the index of the current card by selector, starting from 0.

For preset, this is the preset code from the block manifest

If the source element does not contain type, the method uses the value card. If value is not provided, the method uses index 0.

To create a new card from a preset, specify type with the value preset and pass the preset code from the block manifest in value. For example:

"source": [
          {
            "type": "card",
            "value": 0
          },
          {
            "type": "preset",
            "value": "preset_code"
          }
        ]

Element of the values array

Each element of the values array must be an object that contains one or more node changes.

Key
type

Description

@
string | object | array

Node selector within the card with position indicated by @.

The position is numbered from 0 and indicates which card to modify the node in after applying source.

The format of the value is the same as the data parameter in the landing.block.updatenodes method.

One object in the values array can contain multiple keys for different nodes and positions

If an element of the values array is not an object, the method will skip it without error. For example, in one element of the array, you can change multiple cards at once:

"values": [
          {
            ".landing-block-node-title@0": "First Card",
            ".landing-block-node-title@1": "Card from Preset"
          }
        ]

For detailed information on value formats for different node types, refer to the article landing.block.updatenodes and the overview Node Types.

Returned Data

Name `type`	Description

time `time`	Information about the execution time of the request

Error Handling

HTTP Status: 400

{
            "error": "MISSING_PARAMS",
            "error_description": "Not enough call parameters, missing: data"
        }

Name `type`	Description
error `string`	String error code. It consists of digits, Latin letters, and underscores. It may arrive empty — in that case only `error_description` shows the reason
error_description `string`	Error message for the developer. Do not show it to the end user without processing

Possible Error Codes

Code	Description
`MISSING_PARAMS`	Required parameter `lid`, `block`, or `data` is missing
`LANDING_NOT_EXIST`	Page with identifier `lid` not found or not accessible to the current user
`BLOCK_NOT_FOUND`	Block with identifier `block` not found on page `lid` or not accessible in the draft of the page
`ACCESS_DENIED`	User does not have permission to edit the site
`INCORRECT_AFFECTED`	The server could not confirm that the changes were applied correctly. The error depends on server settings and is not related to the request parameters

Statuses and System Error Codes

HTTP Status: 4xx, 5xx

The errors described below are returned by the REST API itself, not by the logic of a specific method. They can arrive in response to any method.

Status	Code Error Message	Description
`500`	`INTERNAL_SERVER_ERROR` Internal server error	An internal server error has occurred. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support
`500`	`ERROR_UNEXPECTED_ANSWER` Server returned an unexpected response	The server returned an unexpected response. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support
`503`	`QUERY_LIMIT_EXCEEDED` Too many requests	The request intensity limit has been exceeded
`429`	`OPERATION_TIME_LIMIT` Method is blocked due to operation time limit	The method is blocked because the request resource intensity limit has been exceeded. The block is lifted automatically once the accumulated execution time of the method no longer exceeds the limit
`401`	`NO_AUTH_FOUND` Wrong authorization data	The request contains no authorization data: neither an access token nor a webhook code was passed
`401`	`INVALID_REQUEST` Https required	Methods are called over the HTTPS protocol only
`401`	`OVERLOAD_LIMIT` REST API is blocked due to overload	The REST API is blocked due to overload. This is a manual individual block. To have it lifted, contact Bitrix24 technical support
`401`	`ACCESS_DENIED` REST is available only on commercial plans	REST API access is not active for this account. In Bitrix24 Cloud, check the current plan or trial status: Vibe+ plans include REST API access, while Essentials plans do not. A webhook receives a different error message — `REST is available only by subscription`
`401`	`INVALID_CREDENTIALS` Invalid request credentials	No active webhook with the specified user identifier and secret code was found
`404`	`ERROR_METHOD_NOT_FOUND` Method not found!	No method with this name was found. The name is misspelled, the method does not exist in the REST API, or it is unavailable without the required scope
`401`	`insufficient_scope` The request requires higher privileges than provided by the webhook token	The request requires broader permissions than the token has: for a webhook these are the permissions granted to it, for an application it is the scope. For an application, the error message ends with `provided by the access token`
`401`	`expired_token` The access token provided has expired	The access token has expired
`401`	`user_access_error` The user does not have access to the application	The application is installed, but the Bitrix24 administrator has granted access to it only to specific users
`403`	`PORTAL_DELETED` Portal was deleted	The public part of the site is closed. To open it on an on-premise installation, disable the "Temporary closure of the public part of the site" option. Path to the setting: Desktop > Settings > Product Settings > Module Settings > Main Module > Temporary closure of the public part of the site
