How it works
1
Connect
Attach telephony, email, billing, CRM, calendar, and social systems through secure OAuth flows and API keys per tenant.
2
Map
Configure field mapping for CRM sync, catalog feeds, and calendar events — validation catches gaps before data flows.
3
Sync
Bidirectional data sync keeps leads, contacts, deals, appointments, and shop listings up to date across connected systems.
4
Verify
Webhook signatures are cryptographically validated to prevent spoofing and ensure data integrity on every inbound event.
5
Extend
REST APIs and webhooks let you extend further — and we custom-integrate what is not on the standard list so you are never stuck waiting on a generic connector.

FAQ
Do you integrate with Salesforce?
Yes — bidirectional lead sync with configurable field mapping, automatic push/pull, and conflict handling.
Can we build custom integrations?
Yes. We connect the systems you already run — and we custom-integrate what is not on the standard list. Every website and integration is tailored so your team gets the data they need, where they need it, when they need it, and can focus on growing the business. REST APIs and signed webhooks support enterprise workflows when you want to extend further.
Do you replace our DMS or CRM?
We do not replace your DMS. Accounting, desking, and service stay in the system of record you already use. Legible is the growth layer: inventory sync, shopper follow-up, websites, and marketplace feeds — with deep links back to your existing tools.
Which marketplaces and catalogs do you connect?
Google, Meta, TikTok, Cars.com, CarGurus, AutoTrader, and more. Dealer program enrollment is required per vendor. If a portal you need is not listed, we custom-integrate it.
Which telephony provider is used?
Twilio for carrier-grade voice and SMS with real-time media streams; PBX/Asterisk SIP trunk support for hybrid deployments.
Is Stripe supported for billing?
Yes — subscriptions, metered usage, invoicing, payment links, and customer portal flows integrated with client portal billing.
Can I connect Google Calendar?
Yes — OAuth sync for appointment booking from voice, chat, and campaigns with instant two-way updates.
Are social platforms integrated?
Meta, TikTok, YouTube, and LinkedIn connect to Social Growth Engine; catalog sync powers Social Commerce on Meta shop surfaces.
Do you support property management PMS sync?
Yes — Buildium and vertical PMS hooks sync listings and portal deep links for property management marketing workflows.
Are webhook events secure?
Yes — cryptographic signature verification on all inbound provider webhooks prevents spoofed events and ensures data integrity.
