Why teams connect Apollo.io and Syspro

Close the gap between front office and back office: Apollo.io and Syspro share customers and status in real time, in both directions.

Apollo.io holds the customer relationship; Syspro runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Stacksync syncs Sequences, Deals (Opportunities), Tasks and calls, Custom fields in Apollo.io with AR invoices, GL journals, Warehouses, Customers in Syspro field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • Write sales orders from e-commerce platforms or CRMs into SYSPRO without manual re-entry
  • Keep inventory balances and item masters aligned between SYSPRO and a WMS or storefront

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Where Syspro manages people and org data: keep Apollo.io aligned

Owners, territories, and org structure informed by Syspro stay current in Apollo.io.

Where Syspro handles order-to-cash: closed-won flows through

A deal won in Apollo.io creates or updates the customer in Syspro with clean data, so fulfillment and invoicing start without re-entry.

What you can sync between Apollo.io and Syspro

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Apollo.io objects Syspro objects
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Warehouses Stocking locations that scope inventory balances.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Customers AR customer master records matched against CRM accounts.

People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Inventory items The stock master, kept aligned with WMS and e-commerce catalogs.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Sales orders Orders written in from storefronts and CRMs, with status read back out.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Purchase orders Procurement documents synced with supplier portals and receiving.

How the Apollo.io and Syspro connectors work

Apollo.io

Integration surface
REST API
Authentication
API key (passed in request headers); master keys unlock account-wide endpoints
Change detection
Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream
Capabilities
read · write
Rate limits
Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls

Syspro

Integration surface
e.net Solutions business objects, exposed over REST and WCF interfaces in SYSPRO 8
Authentication
SYSPRO operator credentials exchanged for a session token
Change detection
Polling; the ERP does not expose a change feed to external consumers
Capabilities

Rate limits
Throughput depends on the customer's server sizing; many deployments are on-premise
