Set Slots for Resource booking.v1.resource.slots.set

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: booking

Who can execute the method: any user

The method booking.v1.resource.slots.set sets time slots for the specified resource.

The method replaces the entire set of resource slots: slots absent from the request are removed. An empty slots array removes all resource slots, the same way booking.v1.resource.slots.unset does.

After a successful call, the onBookingResourceUpdate event is triggered: slots are retained within the resource itself.

Method Parameters

Required parameters are marked with *

Name
type

Description

resourceId*
integer

Resource identifier.
Can be obtained using the methods booking.v1.resource.add and booking.v1.resource.list

slots*
array

An array of objects containing field values for setting time slots (detailed description)

Parameter slots

Name
type

Description

from*
integer

Time in minutes from the start of the day from which booking is available. Value in the range from 0 to 1440. For example, 540 means booking is available from 9:00 AM

to*
integer

Time in minutes from the start of the day until which booking is available. Value in the range from 0 to 1440 and strictly greater than from. For example, 1080 means booking is available until 6:00 PM

timezone*
string

Time zone in the IANA format relative to which the slot time is set. For example, Europe/Berlin.

An unknown time zone is silently replaced with UTC by the method

weekDays*
array

An array of available weekdays for the slot. Possible values:

  • Mon — Monday
  • Tue — Tuesday
  • Wed — Wednesday
  • Thu — Thursday
  • Fri — Friday
  • Sat — Saturday
  • Sun — Sunday

slotSize*
integer

Booking duration in minutes. The value cannot be negative

All five slot fields are mandatory. The method ignores the id field: slot identifiers are assigned by Bitrix24.

Code Examples

How to Use Examples in Documentation

Example of setting time slots for a resource:

  • availability from Monday to Friday from 9:00 AM to 6:00 PM in the Europe/Berlin time zone

Possible Error Codes

Code

Description

Value

1009

Resource not found

Resource with the specified resourceId not found

0

Required fields: timezone, weekDays, slotSize

Required fields are missing in the slot object. The message lists only the missing ones

422

Invalid range fields

Invalid values in the slot object: from or to outside the 0–1440 range, from greater than or equal to to, an empty or unknown weekday, a negative slotSize. The method does not indicate which field or which slot caused the error

422

Array's element must be array, string given

An element of the slots array is not an object

100

Could not find value for parameter {resourceId}

The resourceId parameter is not provided

100

Could not find value for parameter {slots}

The slots parameter is not provided

0

Booking tool is disabled. Please contact your administrator.

The Booking tool is disabled in the Bitrix24 settings

1007

Failed updating resource

The resource could not be saved

0

Feature is not available

The Booking tool is not available on the current plan

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
