Why teams connect InterSystems IRIS and Resend

Mirror Resend's data into InterSystems IRIS 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 InterSystems IRIS.

Stacksync mirrors Email events, API keys, Emails, Contacts from Resend into Globals, Namespaces, Stored Procedures, Tables in InterSystems IRIS 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.
  • Replicate IRIS tables to Postgres so application teams can build against a familiar database
  • Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access

Automate Resend from your codebase

Write to the synced tables in InterSystems IRIS 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 InterSystems IRIS, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

What you can sync between InterSystems IRIS 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.

InterSystems IRIS objects Resend objects
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Namespaces Namespaces partition databases and determine the connection context for integrations. Broadcasts One-to-many campaign sends addressed to an audience.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Domains Verified sending domains with DNS and DKIM status.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Views SQL views expose curated slices of data for outbound replication. API keys Scoped credentials managed per environment for send and read access.
Schemas Schema organization scopes which tables a sync connection can see. Emails Sent messages retrievable by ID with current delivery status.
