Two-way sync
Changes in Postgres Heroku or SendGrid instantly reflect in both systems. No stale data, no manual imports.
Keep Postgres Heroku and SendGrid in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Postgres Heroku.
Stacksync mirrors Categories, Senders, Single Sends, Unsubscribe Groups from SendGrid into Sequences, Follower Databases, Tables, Views in Postgres Heroku 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.
Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Records from SendGrid are ordinary rows in Postgres Heroku; join them, index them, and use them in application logic without touching the vendor API.
Write to the synced tables in Postgres Heroku and Stacksync propagates the change into SendGrid, replacing custom integration code.
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.
| Postgres Heroku objects | SendGrid objects | |
|---|---|---|
| Views Read-side projections exposed to outbound syncs. | Email Activity Synced with incremental and full sync per the Stacksync docs. | |
| Materialized Views Precomputed result sets synced outward on refresh. | Contacts Marketing recipients upserted from CRM or database records, including custom field values. | |
| Schemas Namespaces that scope which tables a sync reads and writes. | List Synced with incremental and full sync per the Stacksync docs. | |
| Primary and Unique Keys Match keys for idempotent upserts from connected systems. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. | |
| JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. | Categories Synced with incremental and full sync per the Stacksync docs. | |
| Sequences Generate surrogate keys for rows created by inbound syncs. | Senders Synced with incremental and full sync per the Stacksync docs. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Postgres Heroku–SendGrid connection.
Changes in Postgres Heroku or SendGrid instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Postgres Heroku or SendGrid data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Postgres Heroku or SendGrid record.
Track your Postgres Heroku ⇄ SendGrid sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Postgres Heroku and SendGrid.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Postgres Heroku and SendGrid with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Postgres Heroku and SendGrid objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Postgres Heroku and SendGrid: authenticate both systems, choose the objects to sync (such as Postgres Heroku's Views and Materialized Views), map fields visually, and changes propagate both ways in milliseconds — no code required.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Postgres Heroku and SendGrid: One integration pattern for the whole stack; Read SendGrid with a query; Automate SendGrid from your codebase. Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. SendGrid: 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"). Stacksync manages authentication, retries, and rate limits on both sides.
SendGrid: Email Activity access requires an add-on subscription in SendGrid; without it the Email Activity API is not available. Postgres Heroku: All connections require SSL, and server-level settings such as replication configuration are controlled by Heroku rather than the user. Stacksync's field mapping accounts for these differences between Postgres Heroku and SendGrid without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Postgres Heroku and SendGrid records are not retained after a sync operation.
As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
