Get a Custom Field v 3.0 crm.[type].field.custom.get

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: crm

Who can execute the method: a user with the "Edit CRM preferences" permission in CRM

This method belongs to REST 3.0. The call specifics and response format of the new API version are described in the REST 3.0 overview.

The crm.<type>.field.custom.get method returns the description of a custom field: its type, settings, and labels. The object type is set by the <type> segment of the method name.

Method Name for the Object Type

Object type	Method	Fields
Deal	`crm.deal.field.custom.get`	Deal fields
Lead	`crm.lead.field.custom.get`	Lead fields
Contact	`crm.contact.field.custom.get`	Contact fields
Company	`crm.company.field.custom.get`	Company fields
Estimate	`crm.quote.field.custom.get`	Estimate fields
Invoice	`crm.smartinvoice.field.custom.get`	Invoice fields
SPA	`crm.smartprocess<entityTypeId>.field.custom.get`, for example, `crm.smartprocess1038.field.custom.get`	SPA fields

For an SPA, the method name includes the type ID entityTypeId. SPA type IDs are returned by the crm.type.list method in the entityTypeId field. SPAs have custom field methods regardless of the type settings. My company does not have these methods: Bitrix24 responds to crm.mycompany.field.custom.get with the "Method Not Found" error.

The method name is written in lowercase: crm.smartinvoice.field.custom.get, not crm.smartInvoice.field.custom.get. If the name is written in a different case, the method returns the "Method Not Found" error.

Method Parameters

Required parameters are marked with *

Name
type

Description

id*
integer | string

Field ID or name, for example, 6008209 or "UF_CRM_CONTRACT_NUMBER".

Field IDs and names are returned by the crm.<type>.field.custom.list method

select
array

List of field parameters to return, for example, ["id", "name", "settings"]. You can pass id, entityId, and the parameters from the description of the fields parameter of the create method.

By default, the method returns all field parameters

Code Examples

How to Use Examples in Documentation

The new API call differs by adding the /api/ segment to the request URL:

https://{installation_address}/rest/api/{user_id}/{webhook_token}/crm.smartprocess1038.field.custom.get

The examples retrieve the UF_CRM_CONTRACT_NUMBER field of an SPA with the type ID 1038. For a different object type, replace the method name according to the table above.

CRM methods are not yet included in the list of REST 3.0 methods known to $b24.actions.v3.call.make: such a call returns the SDK error JSSDK_CORE_METHOD_NOT_SUPPORT_IN_API_V3. Call the method through the REST 3.0 HTTP client — $b24.getHttpClient(ApiVersion.v3).call.

b24pysdk has no ready-made wrappers for CRM methods, and the SDK sends to REST 3.0 only the methods from the Config().api_v3_methods list. Add the method to this list and call it via bitrix_token.call_method with prefer_version=3.

        Config().configure(api_v3_methods=Config().api_v3_methods | {method})
        
        try:
            response = bitrix_token.call_method(
                api_method=method,
                params={
                    "id": 6008209,

The SDK does not yet support calls to the /rest/api/ address. Use a direct HTTP request, for example, via cURL or fetch.

Returned Data

Name `type`	Description
result `object`	Object with response data
result.item `object`	Field description: field parameters, the field ID `id`, and the object type code `entityId`. The type code is, for example, `CRM_DEAL` for a deal or `CRM_19` for the SPA from the examples. The number in the SPA code is the `id` field from crm.type.list, not `entityTypeId`
time `time`	Information about the request execution time

The method returns labels as strings in the default Bitrix24 language. Each field type has its own settings keys; they are described in the settings parameter of the create method.

Possible Error Codes

Field Not Found

Error Code: BITRIX_REST_V3_REALISATION_EXCEPTION_FIELDNOTFOUNDEXCEPTION, HTTP status: 404

Field	Error description	How to Fix
`-`	Field `#ID#` was not found	Check the field ID or name with the crm.<type>.field.custom.list method. The same error is returned if the field belongs to a different object type or is not available to the user

Request Validation Errors

Error Code: BITRIX_REST_V3_EXCEPTION_VALIDATION_REQUESTVALIDATIONEXCEPTION

Field	Error description	How to Fix
`id`	Required field `id` is missing	Pass the field `id`
`id`	This request requires data type `integer or string starting with UF_` in field `id`	Pass a numeric field ID or a name that starts with `UF_`

Unknown Field Error

Error Code: BITRIX_REST_V3_EXCEPTION_UNKNOWNDTOPROPERTYEXCEPTION

Field	Error description	How to Fix
`-`	Unknown field `#FIELD#` found in entity `CustomFieldConfigDto`	Check the names in `select`: the allowed names are the field parameters, `id`, and `entityId`

Select Format Error

Error Code: BITRIX_REST_V3_EXCEPTION_INVALIDSELECTEXCEPTION

Field	Error description	How to Fix
`-`	Invalid field in `select`: `#VALUE#`	Pass `select` as an array of names, for example, `["id", "name"]`

Method Not Found

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
