Why teams connect Google AlloyDB and SendGrid

Mirror SendGrid's data into Google AlloyDB 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 Google AlloyDB.

Stacksync mirrors Segments, Categories, Senders, Single Sends from SendGrid into Sequences, Replication Slots, Databases, Schemas in Google AlloyDB 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

  • Reconcile transactional email activity with support tickets so agents see what a customer was sent
  • Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
  • Mirror CRM objects into AlloyDB tables so product and internal tools query customer data with plain SQL.
  • Use logical replication to feed AlloyDB changes into warehouses or event pipelines without batch jobs.

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 Google AlloyDB; 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 Google AlloyDB and Stacksync propagates the change into SendGrid, replacing custom integration code.

What you can sync between Google AlloyDB 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.

Google AlloyDB objects SendGrid objects
Replication Slots Logical replication artifacts that back log-based change capture. Segments Query-based contact groups whose membership SendGrid computes from contact fields.
Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Categories Synced with incremental and full sync per the Stacksync docs.
Schemas Namespaces used to separate synced SaaS data from application tables. Senders Synced with incremental and full sync per the Stacksync docs.
Tables Primary read/write target for bi-directional sync with CRMs and other systems. Single Sends One-off marketing campaigns whose stats are read back for reporting.
Views Curated projections used as read-only sync sources. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs.
Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. Email Activity Synced with incremental and full sync per the Stacksync docs.

How the Google AlloyDB and SendGrid connectors work

Google AlloyDB

Integration surface
SQL wire protocol (PostgreSQL-compatible), with connectivity through the AlloyDB Auth Proxy or private IP
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC via PostgreSQL logical replication; polling on timestamp columns as a fallback
Capabilities
read · write · CDC
Rate limits
No API-style rate limits; throughput is bounded by instance size

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
