What integrations do beyond OAuth

Four areas where integrations in Zen-Work go further than a simple OAuth toggle.

zen-work.at/audit-log
Connection audit

Every enabled or removed connection is captured in the audit log — important for compliance and handovers.

zen-work.at/analytics
Per-integration usage stats

How often does a webhook fire, how many events run per tool? Analytics shows load and trend.

zen-work.at/sales-processes/pipeline
CRM sync for sales processes

Sales processes, pipeline stages and deal status sync automatically with external CRMs.

zen-work.at/portal
Customer portal as touchpoint

Tickets, invoices and appointments land in the customer portal via integrations — no custom build.

Use cases

How teams use their integrations

Real-world use cases that simplify daily work.

Calendar synchronization

Project deadlines and absences land automatically in your calendar — without manual data entry.

Workflow automation

When an invoice is paid: chat notification, update accounting, change customer status — all automatically.

Support process

Customer emails are matched by sender, auto-assigned to the right team member, and tracked as tickets. Replies thread back via email.
