Bitrix24 REST API Development and Custom Integrations

We develop on top of the Bitrix24 REST API — outbound sync jobs, inbound webhooks, OAuth applications, and middleware that connects your product to CRM data. Code follows API limits, uses batch calls efficiently, and includes logging for production support.

Who it is for

Product teams embedding Bitrix24 data into their SaaS or mobile app
Integrators needing reliable server-side connectors beyond no-code tools
Companies with complex sync logic that visual automation cannot express

What you get

Production-ready code with monitoring hooks and structured logs
Respect for Bitrix24 rate limits — stable under load
Clear handover: README, env config, and example requests
Ongoing maintenance when Bitrix24 API methods or your schema evolves

What we deliver

Design API integration architecture and authentication (OAuth, incoming webhook)
Implement CRUD operations, batch requests, and event subscriptions
Build retry queues, idempotency, and conflict resolution for sync jobs
Write automated tests against sandbox portals and mock payloads
Document endpoints, field maps, and deployment for your engineering team

How we work

Technical scoping — entities, direction of sync, volume, and security requirements
API design — sequence diagrams, error codes, and staging credentials
Development and integration tests on a dedicated Bitrix24 portal
Deploy to your infrastructure, smoke test, and knowledge transfer session

FAQ

Which languages do you use for Bitrix24 API projects?

Typically PHP, Python, or Node.js depending on your stack. We match your infrastructure and coding standards.

Can you work with on-premise and cloud Bitrix24 portals?

Yes. Authentication and available methods differ slightly; we verify portal type during scoping and adjust the integration design.
