Why teams connect Apollo.io and MarkLogic
Treat Apollo.io like part of your database: its records live in MarkLogic as real tables, and writes in either place sync to the other in seconds.
Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in MarkLogic, where it can be queried and joined like everything else.
Stacksync mirrors Tasks and calls, Custom fields, Contacts, Accounts from Apollo.io into Databases & Forests, Users & Roles, Documents, Collections in MarkLogic with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Apollo.io with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.
Common use cases
- Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
- Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
- Sync curated master data from a MarkLogic data hub into operational CRMs and ERPs.
- Land document data in relational warehouses by reading TDE views as SQL rows.
Trigger workflows from CRM changes
Field and stage updates in Apollo.io arrive as row changes in MarkLogic, ready to drive jobs and notifications.
Query the CRM like a database
Accounts, contacts, and custom objects from Apollo.io become tables in MarkLogic you can join with application data directly.
Product events onto CRM records
Signup, usage, or lifecycle changes written to MarkLogic sync onto the matching records in Apollo.io, giving go-to-market teams live product context.
What you can sync between Apollo.io and MarkLogic
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 | MarkLogic objects | |
|---|---|---|
| Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. | Users & Roles Security principals that govern what an integration credential can read or write. | |
| Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. | Documents JSON and XML documents, the primary records read from and written to the database. | |
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Collections Named groupings used to scope which documents a sync reads or updates. | |
| People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. | Semantic Triples RDF data stored alongside documents, queryable with SPARQL for linked-data syncs. | |
| Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. | TDE Views Relational projections of documents that let syncs read document data as SQL rows. | |
| Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. | Document Metadata & Properties Permissions, quality, and property fragments carried with each document. |

How the Apollo.io and MarkLogic 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
MarkLogic
- Integration surface
- REST API (Client API), plus SQL/ODBC access over TDE views and Java/Node client libraries
- Authentication
- Username/password (digest or basic), with certificate-based options
- Change detection
- No exposed transaction log; polling on document timestamps/metadata, or server-side triggers that record changes for pickup
- Capabilities
- read · write

FAQ
Apollo.io and MarkLogic integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and MarkLogic: authenticate both systems, choose the objects to sync (such as Apollo.io's Custom fields and Contacts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apollo.io and MarkLogic connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apollo.io–MarkLogic integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Apollo.io and MarkLogic. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Apollo.io: Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream. On MarkLogic: No exposed transaction log; polling on document timestamps/metadata, or server-side triggers that record changes for pickup. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Apollo.io side: Tasks and calls, Custom fields, Contacts, Accounts, plus custom fields where Apollo.io exposes them. On the MarkLogic side: Databases & Forests, Users & Roles, Documents, Collections. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
