Request fields (body)

Parameter Type Description
name string First name
lastName string Last name
secondName string Middle name
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). Important: 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). Important: the UPPER form [{ "VALUE": "...", "VALUE_TYPE": "WORK" }] is not accepted — it returns 400 INVALID_MULTIFIELD_SHAPE. Use camelCase: [{ "value": "...", "typeId": "WORK" }]
companyId number Company ID. Lookup: GET /v1/companies
post string Position
comments string Comment
typeId string Contact type. List: GET /v1/statuses?filter[entityId]=CONTACT_TYPE
sourceId string Source. List: GET /v1/statuses?filter[entityId]=SOURCE
sourceDescription string Source description
assignedById number Assigned user. List: GET /v1/users
opened boolean Available to everyone
leadId number ID of the lead the contact was created from
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/contacts/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/contacts/fields.

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 API key lacks the crm scope
401 TOKEN_MISSING API key has no configured tokens
400 INVALID_REQUEST Invalid fields
400 READONLY_FIELD The request body contains a read-only field, such as shortName. Such fields are marked in the RO column of Contact fields
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
