Why teams connect OpenSearch and SendGrid

Mirror SendGrid's data into OpenSearch 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 OpenSearch.

Stacksync mirrors List, Segments, Categories, Senders from SendGrid into Index aliases, Index templates, Ingest pipelines, Data streams in OpenSearch 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

  • Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
  • Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
  • Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.
  • Index support tickets and activity logs from SaaS tools for operational dashboards.

Read SendGrid with a query

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

Automate SendGrid from your codebase

Write to the synced tables in OpenSearch and Stacksync propagates the change into SendGrid, replacing custom integration code.

React to changes as they happen

Updates in SendGrid arrive as row changes in OpenSearch, so triggers, jobs, and services can respond in near real time.

What you can sync between OpenSearch 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.

OpenSearch objects SendGrid objects
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Email Activity Synced with incremental and full sync per the Stacksync docs.
Index templates Mapping and settings presets applied to new indexes a sync creates Contacts Marketing recipients upserted from CRM or database records, including custom field values.
Ingest pipelines Server-side processors that transform documents as they are written List Synced with incremental and full sync per the Stacksync docs.
Data streams Append-oriented time-series storage for logs and events pushed from source systems Segments Query-based contact groups whose membership SendGrid computes from contact fields.
Snapshots Backup artifacts, relevant when reseeding an index from a repository Categories Synced with incremental and full sync per the Stacksync docs.
Indexes The core container; synced records land in indexes with defined mappings Senders Synced with incremental and full sync per the Stacksync docs.

How the OpenSearch and SendGrid connectors work

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas

SendGrid

Integration surface
REST API (v3)
Authentication
API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
Change detection
Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling
Capabilities
read · write · webhooks
Rate limits
Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes
