KeyCRM Limitations

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

API Limitations

KeyCRM API limits depend on the pricing plan. Maximum page size is 50 records. With a large number of product line items, sync delays are possible. Custom statuses require re-running discovery.

General Limitations

LimitationDescription
Page sizeMaximum number of records per 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; you cannot modify data in the CRM

  • Real time: syncing 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 Syncing

When limits are exceeded:

  1. Rate limit: syncing is paused and resumes automatically

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

  3. Large data volume: syncing is split into several cycles
