Complex Integrations · Bitrix24 · Apollo · n8n

Complex Integration (Bitrix24, Apollo, n8n)

We engineered a unified revenue pipeline for a logistics client by tightly integrating Bitrix24 CRM, Apollo for outbound lead generation, and n8n as a central workflow engine. The result: a single source of truth for leads and deals, automated follow-ups, and near real-time insights across marketing, sales, and operations.

Instead of isolated tools and spreadsheets, the client now runs an event-driven integration layer with robust error handling, retries, and observability—designed to scale as new tools and data sources are added to the stack.

Manual effort

−70%

Lead entry, deduping, and status updates automated across systems.

Conversion rate

+40%

Better lead scoring and SLAs on follow-ups from Apollo to Bitrix24.

Sync latency

Real-time

Webhooks and event queues keep CRM and outreach tools aligned.

Data quality

Centralized

Single, enriched contact profile instead of fragmented records.

Integration case study

From disconnected tools to a single revenue backbone

The logistics team already owned powerful tools—Bitrix24, Apollo, and internal reporting—but everything lived in silos. We connected the dots and added an integration layer that actually understands the sales lifecycle from first touch to closed deal.

The challenge
  • Apollo outreach created leads, but CRM data in Bitrix24 lagged behind or was incomplete.
  • Manual CSV imports and ad-hoc scripts led to duplicates and inconsistent fields.
  • No reliable way to track a lead’s journey across cold email, calls, and pipeline stages.
  • Leadership lacked real-time reporting on which campaigns actually produced revenue.
Our approach
  • Designed an event-driven integration architecture around n8n as the layer.
  • Standardized lead and company schemas across Apollo and Bitrix24.
  • Implemented idempotent flows with deduplication rules, conflict resolution, merges.
  • Added monitoring, alerting, and dead-letter queues for failed or delayed sync operations.
Business impact
  • Sales teams work fully inside Bitrix24 while Apollo runs outreach in the background.
  • Hot leads are auto-routed, scored, and assigned with clear SLAs and task sequences.
  • Revenue analytics now attribute deals back to specific Apollo sequences and lists.
  • New providers and tools can be added to the same integration layer without a rebuild.
Integration architecture

How the Bitrix24 · Apollo · n8n integration works

Under the hood, the project runs on a robust integration backbone: webhook listeners, REST APIs, queues, and scheduled jobs coordinated by n8n and backed by modern backend tech.

End-to-end data journey
1. Lead creation in Apollo

Prospects created or enriched in Apollo trigger webhooks or scheduled exports. n8n ingests the payload, normalizes fields (company, contact, lists, sequence), and applies enrichment where needed.

2. Normalization & deduplication

A Node.js/TypeScript microservice layer performs email and domain-based deduping, merges partial records, and enforces a canonical ID strategy before anything touches Bitrix24.

3. Sync to Bitrix24 CRM

Using the Bitrix24 REST API, leads, contacts, and companies are created or updated idempotently. Custom fields store Apollo metadata (sequence, source, list, campaign).

4. Activity & status feedback loop

Replies, opens, clicks, and stage changes are sent back and forth via webhooks and polling jobs. This allows Apollo sequences to pause or branch based on CRM outcomes.

5. Analytics, monitoring & audit trail

Integration logs and metrics are stored in a central datastore and surfaced in dashboards. Each sync event has a traceable ID, making it easy to audit how and when a record moved.
