Leads

CRM lead management: create, retrieve, update, delete, filter.

Bitrix24 API: crm.item.* Scope: crm

A lead may originate from a CRM form; read its ID and fields with GET /v1/crm-forms/:id.

Create lead

POST /v1/leads

Creates a new lead in CRM.

Request fields (body)

Parameter Type Description
title string Lead title
name string Contact first name
lastName string Contact last name
secondName string Middle name
stageId string Lead status — canonical name, the statusId alias is also accepted. Standard: NEW, IN_PROCESS, PROCESSED. A Bitrix24 account may have its own — list: GET /v1/statuses?filter[entityId]=STATUS. In the response the value is returned in the stageId field. Checked literally against the dictionary before the write — a status that does not exist is refused with UNKNOWN_STAGE, no record is created. An empty value is not checked: the lead lands on the default status
opportunity number Amount — canonical name, the amount alias is also accepted. ⚠ For the value to persist, pass isManualOpportunity: true in the same request — otherwise Bitrix24 recalculates the amount from the product rows
isManualOpportunity boolean Manual amount mode (see opportunity)
currency string Currency (alias currencyId). List: GET /v1/currencies
companyTitle string Company name (text, not ID)
phone string | string[] | object[] Phone. Accepts three forms: a string "+1...", an array of strings ["+1...", "+1..."], or an array of objects [{ "value": "+1...", "typeId": "WORK" }, …]. typeId: WORK | HOME | MOBILE | OTHER (default WORK). ⚠ The UPPER form [{ "VALUE": "...", "VALUE_TYPE": "WORK" }] is not accepted — it returns 400 INVALID_MULTIFIELD_SHAPE. Use camelCase: [{ "value": "...", "typeId": "WORK" }]
email string | string[] | object[] Email. Accepts three forms: a string "a@b.com", an array of strings ["a@b.com", "b@c.com"], or an array of objects [{ "value": "a@b.com", "typeId": "WORK" }, …]. typeId: WORK | HOME | MAILING | OTHER (default WORK). ⚠ The UPPER form [{ "VALUE": "...", "VALUE_TYPE": "WORK" }] is not accepted — it returns 400 INVALID_MULTIFIELD_SHAPE. Use camelCase: [{ "value": "...", "typeId": "WORK" }]
post string Position
comments string Comment
sourceId string Source. List: GET /v1/statuses?filter[entityId]=SOURCE
sourceDescription string Source description
assignedById number Assignee. List: GET /v1/users
opened boolean Available to everyone
ufCrm* per field schema A user field of the Bitrix24 account, for example ufCrmProjectCode. The actual name and type are in the schema GET /v1/leads/fields, and the value format for each type is in User fields (UF). An enumeration field takes the option ID from the field's items array in the schema, and a multiple field takes an array of such IDs. If you send the option label VALUE instead of the ID, the value is lost: a single-value field gets 0. A number that is not among the options is stored as is. Neither the label nor a non-existent ID raises an error, and the request returns 201, so map the label to its ID on your side and check the stored value of this field in the response data

Full list of fields: GET /v1/leads/fields.

The response contains all lead fields.

The lead card URL in Bitrix24 is built from id:

<portal> — the Bitrix24 portal domain. Access is limited by the employee's permissions in Bitrix24.

Error response example

403 — no scope:

JSON 
{
  "success": false,
  "error": {
    "code": "SCOPE_DENIED",
    "message": "This endpoint requires 'crm' scope"
  }
}

Errors

HTTP Code Description
403 SCOPE_DENIED The API key does not have the crm scope
401 TOKEN_MISSING The API key has no configured tokens
400 INVALID_MULTIFIELD_SHAPE Wrong shape for phone or email — expects [{ "value", "typeId" }]
400 MULTIFIELD_ID_NOT_SUPPORTED phone, email or the raw fm[] contains an object with an id field. There is nothing to address on create: Bitrix24 assigns multifield row ids itself, so the request is refused and nothing is written
400 READONLY_FIELD Attempt to write a read-only field
400 UNKNOWN_STAGE stageId / statusId is not in the lead status dictionary (STATUS): a typo, a different letter case, a deal stage instead of a lead status. No record is created; message suggests the exact spelling, details.knownStages lists the dictionary's statuses

Full list of common API errors — Errors.

Known specifics

Simple CRM mode (no leads): when the Bitrix24 account runs CRM in simple mode, Bitrix24 converts the lead right on creation — it comes back CONVERTED and closed, with a contact and a deal created from it that the request never asked for. The requested stage is not kept. Vibecode changes nothing in the request: this is Bitrix24's own behaviour, and the mode cannot be switched through the API — only in the CRM settings. The response stays 201, and meta.warnings gets a LEAD_AUTO_CONVERTED warning with the ids of the contact (contactId) and deal (dealId) Bitrix24 created; null when the record was not created or not found: a contact you bound yourself via contactId is reused by Bitrix24 and does not count as created. There is no warning when CONVERTED was requested explicitly. On such an account, create deals and contacts directly.

Lead conversion: Bitrix24 REST has no dedicated conversion method. To "convert" a lead, create a deal/contact/company with leadId and update the lead status:

javascript 
// 1. Create a deal from the lead
await fetch('/v1/deals', { body: { title: 'From lead', leadId: 5001 } })
// 2. Close the lead
await fetch('/v1/leads/5001', { method: 'PATCH', body: { statusId: 'CONVERTED' } })
