Why teams connect Apollo.io and IBM AS/400

Treat Apollo.io like part of your database: its records live in IBM AS/400 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 IBM AS/400, where it can be queried and joined like everything else.

Stacksync mirrors Contacts, Accounts, People (database records), Sequences from Apollo.io into Rows / records, Journals and journal receivers, Data queues, Libraries in IBM AS/400 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.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.

Query the CRM like a database

Accounts, contacts, and custom objects from Apollo.io become tables in IBM AS/400 you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to IBM AS/400 sync onto the matching records in Apollo.io, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Apollo.io API, limits, and retries.

What you can sync between Apollo.io and IBM AS/400

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 IBM AS/400 objects
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Members Sub-partitions of files in legacy applications, flattened or selected during syncs.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Rows / records The unit of read and write, accessed via SQL or record-level access.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Journals and journal receivers The change log that enables log-based CDC on journaled files.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Libraries The schema-equivalent containers that scope which files a sync reads.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Physical files (tables) The Db2 for i tables mapped directly to sync targets.

How the Apollo.io and IBM AS/400 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

IBM AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.
