Why teams connect InterSystems IRIS and SendGrid

Mirror SendGrid'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 SendGrid 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 Activity, Contacts, List, Segments from SendGrid into Views, Schemas, Persistent Classes, Globals 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 SendGrid, so the tool and the database never disagree.

Common use cases

  • 01 Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
  • 02 Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
  • 03 Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • 04 Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting

Common sync patterns

React to changes as they happen

Updates in SendGrid 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.

Read SendGrid with a query

Records from SendGrid are ordinary rows in InterSystems IRIS; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between InterSystems IRIS and SendGrid

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 SendGrid objects How this pairing syncs
Schemas Schema organization scopes which tables a sync connection can see. Contacts Marketing recipients upserted from CRM or database records, including custom field values. Schemas is specific to InterSystems IRIS and Contacts to SendGrid — each maps to any object or custom field on the other side.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. List Synced with incremental and full sync per the Stacksync docs. Persistent Classes is specific to InterSystems IRIS and List to SendGrid — each maps to any object or custom field on the other side.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Globals is specific to InterSystems IRIS and Segments to SendGrid — each maps to any object or custom field on the other side.
Namespaces Namespaces partition databases and determine the connection context for integrations. Categories Synced with incremental and full sync per the Stacksync docs. Namespaces is specific to InterSystems IRIS and Categories to SendGrid — each maps to any object or custom field on the other side.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Senders Synced with incremental and full sync per the Stacksync docs. Stored Procedures is specific to InterSystems IRIS and Senders to SendGrid — each maps to any object or custom field on the other side.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Single Sends One-off marketing campaigns whose stats are read back for reporting. Tables is specific to InterSystems IRIS and Single Sends to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS and SendGrid

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

InterSystems IRIS SendGrid Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.

SendGrid InterSystems IRIS Sub-second propagation

DetectionSendGrid notifies Stacksync of record changes through webhook events. Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint.

DeliveryEach detected change is applied to InterSystems IRIS as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
