Change HTML Tag of a Block Element landing.block.changeNodeName
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:
landingWho can execute the method: a user with "edit" access permission for the site containing the page.
The method landing.block.changeNodeName changes the HTML tag of a block element in the draft of a page.
If the page is already published, changes will be visible to visitors after re-publishing through the interface or using the method landing.landing.publication.
Method Parameters
Required parameters are marked with *
|
Name |
Description |
|
scope |
Internal scope of landings. It is not related to the REST scope The value of |
|
lid* |
Identifier of the page The page identifier can be obtained using the method landing.landing.getList |
|
block* |
Identifier of the block in the draft of the page The block identifier can be obtained using the method landing.block.getlist with the parameter Use the identifier specifically from the draft of the page. If you pass the identifier of a block from the published version or another version of the page, the changes will not be applied |
|
data* |
Set of changes for block elements (detailed description) |
|
preventHistory |
If By default, it is |
Parameter data
The data parameter is passed in the format:
{
selector_1: tag_1,
selector_2: tag_2,
...,
selector_n: tag_n
}
where:
selector_n— selector of the element from the block manifesttag_n— new name of the HTML tag
|
Key |
Description |
|
New name of the HTML tag for the element specified in the key The key must match the selector of the element from the block manifest. For repeating elements, you can specify the position after the selector using If the position is not specified, the method will change the first found element, which means it will work the same as If you pass a selector that does not exist in the block manifest or specify a position that does not exist in the block, the method will complete without an error but will not change anything. |
Allowed Tag Values
The tag value is passed as a string. Leading and trailing spaces in the value are removed, and case is ignored.
|

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 |
Description |
|
|
|
An internal server error has occurred. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support |
|
|
|
The server returned an unexpected response. Retry the call, and if the error persists, contact the server administrator or Bitrix24 technical support |
|
|
|
The request intensity limit has been exceeded |
|
|
|
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 |
|
|
|
The request contains no authorization data: neither an access token nor a webhook code was passed |
|
|
|
Methods are called over the HTTPS protocol only |
|
|
|
The REST API is blocked due to overload. This is a manual individual block. To have it lifted, contact Bitrix24 technical support |
|
|
|
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 — |
|
|
|
No active webhook with the specified user identifier and secret code was 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 |
|
|
|
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 |
|
|
|
The access token has expired |
|
|
|
The application is installed, but the Bitrix24 administrator has granted access to it only to specific users |
