Why teams connect Apollo.io and NextGen Healthcare

Sync what happens in NextGen Healthcare with the customer records in Apollo.io, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever NextGen Healthcare holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Clinical Documents, Medications & Allergies, Lab Results, Insurance / Coverage in NextGen Healthcare to Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with bi-directional, real-time sync. Activity and record changes in NextGen Healthcare update the matching contact or account in Apollo.io, and CRM data flows the other way wherever NextGen Healthcare can store and use it.

Common use cases

  • Keep provider directories consistent between the EHR, the website, and scheduling tools.
  • Feed referral data into intake workflows so new patients are registered without rekeying.
  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
