Why teams connect IBM AS/400 and Resend

Mirror Resend's data into IBM AS/400 so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Resend through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in IBM AS/400.

Stacksync mirrors Domains, Email events, API keys, Emails from Resend into Rows / records, Journals and journal receivers, Data queues, Libraries in IBM AS/400 and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Resend, so the tool and the database never disagree.

Common use cases

  • Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
  • Feed open and click events into a warehouse for engagement analytics alongside product data.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

Read Resend with a query

Records from Resend are ordinary rows in IBM AS/400; join them, index them, and use them in application logic without touching the vendor API.

Automate Resend from your codebase

Write to the synced tables in IBM AS/400 and Stacksync propagates the change into Resend, replacing custom integration code.

React to changes as they happen

Updates in Resend arrive as row changes in IBM AS/400, so triggers, jobs, and services can respond in near real time.

What you can sync between IBM AS/400 and Resend

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.

IBM AS/400 objects Resend objects
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Domains Verified sending domains with DNS and DKIM status.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. API keys Scoped credentials managed per environment for send and read access.
Rows / records The unit of read and write, accessed via SQL or record-level access. Emails Sent messages retrievable by ID with current delivery status.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
