Bitrix24 Limitations

This article describes the limitations of the Bitrix24 connector in LightLead.

API Limitations

Bitrix24 API limit: 2 requests per second per webhook. Batch request size — up to 50 methods. Some plans restrict REST API access. UTM tags are only available on CRM+ plans.

General Limitations

LimitationDescription
Page sizeMaximum number of records in a single request
Request rateMaximum number of requests per unit of time
Data volumeLimit on the total volume of data loaded
History depthMaximum period of historical data
Number of connectionsMaximum number of active connections

Unsupported Features

The following features are currently not supported:

  • Writing data: the connector is read-only, changing data in the CRM is not possible

  • Real time: sync is periodic, not real-time

  • Attachments and files: fields of type "file" are not loaded

  • Notes and comments: text notes on deals are not synced

  • Tasks and activities: task and meeting history is not loaded

Impact on Synchronization

When limits are exceeded:

  1. Rate limit: sync pauses and resumes automatically

  2. Timeout: the request is retried with an increased interval

  3. Large data volume: sync is split across several cycles
