Close the Call Card from the Application CallCardClose
If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.
Scope:
placement— registration of the placement,telephony— registration of the call that raises the cardWho can execute the command: any user
The CallCardClose command closes the call card.
The command operates within the application context in the PAGE_BACKGROUND_WORKER placement. This is a JS interface command, not a REST method: it cannot be invoked with a request to /rest/.
How to Call the Command
The command is invoked from the widget with the BX24.placement.call method. The third argument is the callback function, which receives the result of the command.
BX24.placement.call('CallCardClose', {}, function (result) {
console.log(result);
});
Command Parameters
The command takes no parameters. Pass an empty object {} as the second argument.
Warning
After CallCardClose is invoked, the card can no longer be managed.
Code Examples
How to Use Examples in Documentation
It is recommended to call the command after the BackgroundCallCard::initialized event
BX24.ready(function () {
BX24.init(function () {
BX24.placement.call('CallCardClose', {}, function (result) {
console.log(result);
});
});
});
// $b24 is an already-initialized SDK instance (see the SDK "Get started" guide)
import type { B24Frame } from '@bitrix24/b24jssdk'
declare const $b24: B24Frame
await $b24.placement.call('CallCardClose')
<!-- Load the SDK (UMD build); it is exposed as the global B24Js -->
<script src="https://unpkg.com/@bitrix24/b24jssdk@1/dist/umd/index.min.js"></script>
<script>
document.addEventListener('DOMContentLoaded', async () => {
const $b24 = await B24Js.initializeB24Frame()
const result = await $b24.placement.call('CallCardClose')
console.log(result)
})
</script>
Command Result
[]
Returned Data
An empty array on a successful call.
Errors
The command error arrives in the same callback function: instead of the usual result, it receives an array with an object whose result equals error.
[
{
"result": "error",
"errorCode": "Call card is undefined"
}
]

If the command is invoked in another placement, the callback function will not be invoked at all: the placement interface ignores an unknown command. To check that the CallCardClose command is available, use the BX24.placement.getInterface method.
