Custom integrations & development

When a native connector is missing or loses data, we build the integration for the task. API, webhooks, widgets, event handlers, and microservices for Kommo, HubSpot, Salesforce, and Pipedrive.

What we build for CRMs

Standard CRM tooling isn't always enough. When a native connector is missing, covers only part of the scenario, or loses deal context - we develop the integration and logic for the task: via API, webhooks, and event handlers. Data ends up where it's needed, not "somewhere nearby".

What we work on

  • API and webhook integrations - two-way exchange with telephony, payments, messengers, e-commerce, and BI.
  • Widgets and handlers - custom elements inside the CRM interface and reactions to pipeline events.
  • Microservices and queues - when data exchange must be reliable and scalable.
  • Replacing fragile chains - moving critical flows off Zapier and native connectors to direct integration.

How native integrations break

"There is an integration" and "the data is where it should be" are different things. The typical failures look like this:

  • Data lands in the wrong place. A call, a signature or a payment is written into a note on the deal instead of its own field - and no report can be built from it.
  • The association is lost. The activity attaches to the contact rather than the deal, so the deal card shows nothing of what happened.
  • Sync goes one way. Changes reach the service but never come back, and the two systems drift apart.
  • Duplicates appear. Systems identify the same customer by different keys - email in one, an internal id in the other.

Worked examples: when a native integration loses data, hidden fees in payments, when Zapier becomes an antipattern.

When Zapier is enough, and when it is not

We have nothing against no-code - it covers rare, non-critical scenarios well. The trouble starts when money depends on the flow: there is no proper error handling or retry, a failed task simply disappears, and cost grows with the number of operations. If a scenario is critical, high-volume or needs its own logic, building the integration directly is cheaper than repairing the chain after every outage.

For which systems

We build integrations for Kommo, HubSpot, Salesforce, and Pipedrive. The approach is the same - we map where standard functionality falls short and close it with development.

FAQ

When is a custom integration needed instead of a native one?

When there is no native connector, it covers only part of the scenario, or it loses context - activities don't attach to the deal, syncing is partial, duplicates appear. In those cases we build an integration for the task via API and webhooks.

What do you develop for CRMs?

API integrations, webhooks and event handlers, widgets inside the CRM interface, microservices and queues for data exchange, and syncing with external systems (telephony, payments, messengers, BI, e-commerce).

Which CRMs do you build integrations for?

Kommo, HubSpot, Salesforce, and Pipedrive. The approach is the same: we map where standard functionality falls short and close it with custom development.

What's wrong with Zapier for connecting systems?

Zapier is handy for simple scenarios, but at scale it hits limits, delays, and fragility: on failure data is lost and logic is hard to control. For critical flows a direct API integration is more reliable.
