Why teams connect IBM AS/400 and Twenty CRM

Treat Twenty CRM 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 Companies, Opportunities, Tasks, Notes from Twenty CRM into Physical files (tables), Logical files (views), Members, Rows / records 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 Twenty CRM 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

  • Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
  • Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.
  • 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.

Trigger workflows from CRM changes

Rows / records The unit of read and write, accessed via SQL or record-level access. Opportunities Deal records tracked through pipeline stages, synced for forecasting.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Tasks To-dos linked to people, companies, or deals.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Notes Free-form notes attached to records, useful for mirroring activity from other tools.
Libraries The schema-equivalent containers that scope which files a sync reads. Custom Objects User-defined objects created in Twenty's data model settings, addressable through the same APIs as standard objects.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Attachments Files linked to records.
