How long does it take to set up an integration?

Most integrations can be connected in under 5 minutes through our one-click OAuth flow. CRM integrations like HubSpot and Salesforce include a guided field-mapping wizard that takes about 10 minutes. No engineering required.

Is data synced in real time?

Yes. All integrations use real-time event-driven syncing via webhooks. CRM data, calendar bookings, and notifications propagate within seconds. For bulk historical imports, we run a one-time batch sync during onboarding.

Can I build custom integrations with the API?

Absolutely. Sellinger provides a comprehensive REST API and outbound webhooks. You can trigger sequences, pull analytics, sync contacts, and listen for events like replies, meetings booked, or lead status changes.

Do integrations cost extra?

No. All native integrations are included in every Sellinger plan at no additional cost. API access is available on Growth plans and above.

What happens if an integration disconnects?

Sellinger monitors every connected integration in real time. If a token expires or a connection drops, we notify you immediately via email and Slack, and queue all events for automatic replay once reconnected.

Can I use multiple CRMs at once?

Yes. You can connect HubSpot and Salesforce simultaneously, with independent field mappings and sync rules for each. This is useful for teams migrating between CRMs or managing multiple business units.
