My Company Fields in REST 3.0

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

These fields belong to REST 3.0 methods. The call specifics and response format of the new API version are described in the REST 3.0 overview.

My company is a company from the "My companies" reference list on whose behalf you work with clients. It is selected in deals, invoices, estimates, and SPAs, for example, in the myCompanyId field of an invoice.

My company fields are returned by the crm.mycompany.get and crm.mycompany.list methods and accepted by the crm.mycompany.add and crm.mycompany.update methods. Values of multiple fields are added and removed one at a time by the crm.mycompany.addfieldvalue and crm.mycompany.deletefieldvalue methods. The list of fields with their attributes is returned by the crm.mycompany.field.list method.

My company is structured like a regular CRM company, but the crm.mycompany.* and crm.company.* methods do not overlap. crm.mycompany.get with the ID of a client company returns the error 'Entity with ID … was not found', and crm.mycompany.list does not show client companies. The fields of client companies are described in the Company Fields in REST 3.0 article.

My company has no custom field methods crm.mycompany.field.custom.* and no required field methods crm.mycompany.field.required.*. My companies share custom fields with client companies. For details, see the Custom Fields section.

Some fields exist in two forms: as an ID and as a related object, for example, assignedById and assignedBy. The ID can be passed when writing data, while the related object can only be requested in select.

Which Fields the Methods Accept and Return

Method	Accepts	Returns
crm.mycompany.add	Fields of the My Company Object table that can be edited, and custom fields. The `title` field is required, otherwise the method returns the error 'Required field "title" is empty'	ID of the created company `id`
crm.mycompany.update	Company `id` and the same fields as `add`. Fields not included in `fields` keep their current values	Success flag `true`
crm.mycompany.get	Company `id` and `select`	Without `select`, only `id`. With `select`, only the listed fields; `id` is not added automatically. A whole related object, for example, `assignedBy`, returns all of its fields, while a dot-notation path, for example, `assignedBy.firstName`, returns only the selected ones. For details, see the Related Objects section
crm.mycompany.list	`select`, `filter`, `order`, `pagination`	Without `select`, only the `id` of each company. Fields and related objects are requested in `select` the same way as in `get`
crm.mycompany.addfieldvalue, crm.mycompany.deletefieldvalue	Company `id`, the multiple field name `fieldName`, and the value `value`. Supported fields are `phone`, `email`, `web`, `im`, `contactsId`, `observersId`, and multiple custom fields. For other fields, the method returns the error 'The field is not supported.'	Success flag `true`
crm.mycompany.basic.get, crm.mycompany.basic.list	`basic.get` — `id` and `select`, `basic.list` — `select`, `filter`, `order`, `pagination`	A reduced set of data: `id`, `title`, `phone`, `email`, requisites `requisites`, and bank details `bankRequisites`. Without `select`, `id` and `title`. For details, see the method pages

The add and update methods do not accept fields marked "read-only" and return the BITRIX_REST_V3_EXCEPTION_VALIDATION_DTOVALIDATIONEXCEPTION error with the message 'Field "contactId" is read-only.' Related objects, for example, contacts and assignedBy, are also read-only: to write data, pass the ID — contactsId, assignedById.

The method validates fields with values from reference lists when writing data. If the value is not in the reference list, the method returns the error 'Field value is not one of the possible values'. For the company type, industry, number of employees, and currency, the error message lists the allowed values.

Boolean fields accept and return true or false. The values Y, N, 1, and 0 are not accepted: the method returns the error 'This request requires data type "bool" in field "opened"'.

Fields of the datetime type are returned in ISO 8601 format, for example, 2026-11-03T14:42:01+03:00. In a filter by a datetime field, also pass a date with time.

You can filter and sort only by the fields whose description says so. For other fields, the list method returns an error stating that the field 'requires attribute "Filterable"' or '"Sortable"'. Dot notation lets you filter by fields of linked CRM items, of phone, email, website, and messenger values, and of the utm and lastCommunication objects, for example, ["contact.name", "=", "Klaus"] or ["phone.value", "=", "+49300000001"]. Filtering by fields of employees and reference lists, for example, assignedBy.id or industry.name, is not supported: the method returns the BITRIX_REST_V3_EXCEPTION_INVALIDFILTEREXCEPTION error. The filter format is described on the crm.<type>.list page and in the REST API 3.0 Overview article.

The crm.mycompany.field.list response differs from the actual field format. For createdTime, updatedTime, and lastActivityTime, the type is object, but datetime strings are returned. For phone, email, web, and im, multiple: false is specified, but arrays are returned. For observersId and contactsId, the element type is object, but integers are passed and returned. The validationRules are returned as empty objects {}. Rely on the My Company Object table.

Phone Numbers, Email Addresses, Websites, and Messengers

The phone, email, web, and im fields are arrays of values. Each value is an object with these fields:

Name `type`	Description
id `integer`	Value ID. Assigned when the value is written and cannot be passed: the method returns the error 'Field "id" is read-only'
valueTypeId `string`	Value type, for example, `WORK` or `MOBILE`. Required when writing data. The allowed types for each field are returned by the crm.dictionary.phonetype.list, crm.dictionary.emailtype.list, crm.dictionary.webtype.list, and crm.dictionary.imtype.list methods
valueType `object`	Value type with its name: `id`, `name` — full name, for example, `Work Phone`, `nameShort` — short name, for example, `Work Phone`. Read-only
value `string`	Value: a phone number, email address, website address, or messenger ID. Required when writing data

When writing data, pass an array of objects with the valueTypeId and value fields:

{
            "phone": [
                {"valueTypeId": "WORK", "value": "+49300000001"},
                {"valueTypeId": "MOBILE", "value": "+49300000002"}
            ]
        }

In the response, each value is returned with id and the valueType object:

{
            "phone": [
                {
                    "id": 8861,
                    "valueTypeId": "WORK",
                    "valueType": {
                        "id": "WORK",
                        "name": "Work Phone",
                        "nameShort": "Work Phone"
                    },
                    "value": "+49300000001"
                }
            ]
        }

How writing works:

crm.mycompany.update replaces all values of the field with the passed array. Values not in the array are deleted. Other multiple fields not included in fields stay unchanged
an empty array, for example, "phone": [], deletes all values of the field
a single value is added by the crm.mycompany.addfieldvalue method and removed by crm.mycompany.deletefieldvalue. In value, pass the object {"valueTypeId": "WORK", "value": "+49300000001"}. If such a value already exists, addfieldvalue returns the error 'The field value already exists.'
one field can hold up to 50 values, and all four fields together up to 100. If the limit is exceeded, the method returns the error 'Too many phone multifields.'

File Object

Field logo. To upload a logo, pass the upload object with the file name and the content in Base64 or a link to the file:

{
            "logo": {
                "upload": {
                    "name": "logo.png",
                    "data": "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8z8DwHwAFBQIAX8jx0gAAAABJRU5ErkJggg=="
                }
            }
        }

Instead of data, you can pass url — the file address. You cannot pass data and url at the same time.

In the response, the field contains the data of the uploaded file:

Name `type`	Description
id `string`	File ID, for example, `"39935"`
name `string`	File name
url `string`	Address for viewing the file in Bitrix24
downloadUrl `string`	Address for downloading the file via REST. The address contains webhook authorization data, do not publish it

UTM Tags Object

Field utm. When writing data, pass only the tags you need: on creation, the other tags are set to null; on update, they keep their current values. Each tag is a string of up to 255 characters.

Name `type`	Description
source `string \| null`	Ad platform, the `utm_source` tag, for example, `google`
medium `string \| null`	Traffic type, the `utm_medium` tag, for example, `cpc`
campaign `string \| null`	Ad campaign, the `utm_campaign` tag
content `string \| null`	Ad content, the `utm_content` tag
term `string \| null`	Keyword, the `utm_term` tag

The related<type code>Id and related<type code> fields appear when Bitrix24 has a link configured in which the company is subordinate to an SPA. For each parent SPA, the company has a pair of fields:

related<type code>Id — ID of the parent item, for example, relatedSmartProcess177Id for the SPA with entityTypeId = 177
related<type code> — the parent item as an object of type CRM item, for example, relatedSmartProcess177

The field title in the field.list response matches the name of the parent SPA, for example, "Equipment purchase". The method checks that an item with the passed ID exists. If there is no such item, the method returns the error 'Field value is not one of the possible values'.

The set of these fields depends on the links configured in Bitrix24. The current list is returned by the crm.mycompany.field.list method.

Related Objects

A related object is requested in select by the field name without the Id suffix: assignedBy, industry, contacts. The whole object name returns all of its fields, and a dot-notation path returns only the selected ones, for example, ["type.name", "assignedBy.firstName"]. The path supports one level of nesting: the method does not accept contact.createdBy.firstName.

A linked CRM item — contact, contacts, lead, related<type code> — returns only id when requested by its whole name. Request the other item fields using dot notation. Dot notation gives access to the fields of the CRM item object and to any fields of the linked item's type, for example, ["contacts.title", "contacts.phone", "contact.post"]. Contact fields are described in the Contact Fields in REST 3.0 article.

If a link is not set, the object is returned as null, and an array of objects, for example, observers or contacts, is returned as an empty array.

Employee Object

Fields createdBy, updatedBy, lastActivityBy, assignedBy, observers.

Name `type`	Description
id `integer`	User ID
firstName `string`	First name
lastName `string`	Last name
personalGender `string \| null`	Gender: `M` — male, `F` — female. If the gender is not specified, `null`
url `string`	Relative link to the user profile, for example, `/company/personal/user/1/`
personalPhoto `string \| null`	Link to the user photo. If there is no photo, `null`

CRM Item Object

Fields contact, contacts, lead, related<type code>.

Name `type`	Description
id `integer`	Item ID
entityTypeId `integer`	Object type ID, for example, `3` — contact, `1` — lead
canRead `boolean`	Whether the current user can view the item
title `string`	Item title. For a contact, the last name, first name, and middle name
url `string`	Relative link to the item card, for example, `/crm/contact/details/3211/`

Reference List Value Object

Fields type, industry, employees.

Name `type`	Description
id `string`	Value ID, for example, `IT`
name `string`	Value name, for example, `Information technology`
sort `integer`	Sort order

CRM Form Object

Field webform.

Name `type`	Description

Last Communication Object

Field lastCommunication. If there has been no communication of a given kind, the corresponding field is null.

Name `type`	Description
communicationTime `datetime \| null`	Date and time of the last communication of any kind
callTime `datetime \| null`	Date and time of the last call
emailTime `datetime \| null`	Date and time of the last email
imolTime `datetime \| null`	Date and time of the last message in an open channel
webformTime `datetime \| null`	Date and time the CRM form was last submitted

Currency Object

Field currency.

Name `type`	Description
id `string`	Currency code, for example, `EUR`
fullName `string`	Currency name
formatString `string`	Amount display template. The `#` character is replaced with the amount. The currency sign is returned as an HTML entity, for example, `€#`
decPoint `string`	Decimal separator
thousandsSep `string`	Thousands separator. May be returned as an HTML entity, for example, ` `
decimals `integer`	Number of decimal places
hideZero `boolean`	Whether to hide insignificant trailing zeros in the fractional part
amount `double`	Exchange rate relative to the base currency
amountCount `integer`	Number of currency units the exchange rate applies to
base `boolean`	Base currency: `true` — yes, `false` — no
sort `integer`	Sort order
numericCode `string`	Numeric currency code, for example, `978`
languageId `string`	Language for which the name and format are set
createdTime `datetime \| null`	Date and time the currency was created
updatedTime `datetime \| null`	Date and time the currency was updated
createdById `integer \| null`	ID of the user who created the currency
updatedById `integer \| null`	ID of the user who updated the currency

Custom Fields

My companies and client companies share custom fields: these are the same UF_CRM_<code> fields, for example, UF_CRM_1687188367. They are passed and requested by name in the same way as standard fields. My company has no custom field methods of its own: crm.mycompany.field.custom.list returns the BITRIX_REST_V3_EXCEPTION_METHODNOTFOUNDEXCEPTION error. The list of fields is returned by the crm.company.field.custom.list method, and the fields are created and updated by the crm.company.field.custom.* methods.

The value of a "Money" field is passed as an object {"sum": 150.5, "currencyId": "EUR"}. A string such as 150.5|EUR is not accepted: the method returns the error 'This request requires data type "MoneyDto" in field "UF_CRM_…"'.

Each custom field has a paired UF_CRM_…_data field, which is read-only and requested in select. It contains the value in several representations:

value — the value in the same format as in the field itself
rawValue — the value in the storage format, for example, 150.5|EUR for a "Money" field
formattedValue — the value for display to the user: 150.50 € for money, the employee name for a "Link to employee" field
extra — additional data: for money, amount, currencyId, and currencyFullName; for an employee, the fields of the employee object. For a string, number, and date, null

For a multiple custom field, UF_CRM_…_data is an array of such objects.
