Known specifics

Search for an existing CRM entity when crmCreate: true. Bitrix24 first looks for a lead, contact, or company with a matching phone number. On a match, crmEntityId points to the existing entity and crmCreatedLead stays null. A new lead is created only if there are no matches.

CRM_* fields are empty when crmCreate: false. A CRM link can be created automatically when the call is finished via POST /v1/calls/:callId/finish if Bitrix24 finds a matching number at that point.

callId is a required parameter for all subsequent steps. Save it right away: all show, hide, finish, transcription operations take callId in the request path.
