Change the Anchor of the Block landing.block.changeAnchor
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
The method landing.block.changeAnchor modifies or removes a custom anchor of a block in the draft of a page.
If the page is already published, changes will be visible to visitors after publishing the updates through the interface or using the method landing.landing.publication.

Information about the execution time of the request |
Error Handling
HTTP Status: 400
{
"error": "BAD_ANCHOR",
"error_description": "The anchor must start with a character from a-z and may only contain characters from \"a-z\", \"0-9\", \"-\", \"_\", \".\", \":\""
}
|
Name |
Description |
|
error |
String error code. It consists of digits, Latin letters, and underscores. It may arrive empty — in that case only |
|
error_description |
Error message for the developer. Do not show it to the end user without processing |
Possible Error Codes
|
Code |
Description |
|
|
Required parameter |
|
|
The page with identifier |
|
|
The block with identifier |
|
|
Insufficient rights to edit the site |
|
|
An invalid anchor was provided: it does not start with a letter, contains forbidden characters, or consists of a single character |
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 |
|
|
|
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 |
