Can you integrate Postgres Heroku with Vtiger CRM?

Yes. Stacksync provides a managed, real-time two-way integration between Postgres Heroku and Vtiger CRM: authenticate both systems, choose the objects to sync (such as Postgres Heroku's Schemas and Primary and Unique Keys), map fields visually, and changes propagate both ways in milliseconds — no code required.

Can the Postgres Heroku–Vtiger CRM sync run one-way instead of two-way?

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.

How do teams use the Postgres Heroku and Vtiger CRM integration?

Common patterns for Postgres Heroku and Vtiger CRM: Internal tools without API code; Trigger workflows from CRM changes; Query the CRM like a database. Back-office apps read and write the synced tables; Stacksync handles the Vtiger CRM API, limits, and retries.

What should I know about the two APIs?

Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. Vtiger CRM: REST API. Authentication: HTTP Basic with username and access key. Stacksync manages authentication, retries, and rate limits on both sides.

What makes Vtiger CRM's data model different?

Vtiger CRM: Record IDs carry a module-type prefix (for example 12x1023), so the ID itself identifies which module a record belongs to. 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 Vtiger CRM without custom code.

Is the Postgres Heroku–Vtiger CRM integration secure?

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 Vtiger CRM records are not retained after a sync operation.

Why teams connect Postgres Heroku and Vtiger CRM

Treat Vtiger CRM like part of your database: its records live in Postgres Heroku as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Postgres Heroku, where it can be queried and joined like everything else.

Stacksync mirrors Contacts, Organizations, Leads, Opportunities from Vtiger CRM into Primary and Unique Keys, JSONB Columns, Sequences, Follower Databases in Postgres Heroku with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Vtiger CRM with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

Two-way contact and organization sync between Vtiger and a billing or ERP system.
Sync Cases to an external help desk or engineering tracker so support and product teams work from the same tickets.
Sync Heroku Postgres into a warehouse for reporting without running ETL dynos
Keep several Heroku app databases aligned with one system of record

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Vtiger CRM API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Vtiger CRM arrive as row changes in Postgres Heroku, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Vtiger CRM become tables in Postgres Heroku you can join with application data directly.

What you can sync between Postgres Heroku and Vtiger CRM

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		Vtiger CRM objects
Schemas Namespaces that scope which tables a sync reads and writes.	⇄	Organizations Company and account records.
Primary and Unique Keys Match keys for idempotent upserts from connected systems.	⇄	Leads Unqualified prospects that convert into contacts, organizations, and opportunities.
JSONB Columns Semi-structured payloads for nested SaaS objects and metadata.	⇄	Opportunities Deal records, historically the Potentials module, synced for pipeline reporting.
Sequences Generate surrogate keys for rows created by inbound syncs.	⇄	Cases Support tickets from the help-desk module, mirrored to external trackers.
Follower Databases Heroku-managed read replicas usable as low-impact sync sources.	⇄	Products Catalog items referenced on quotes, orders, and invoices.
Tables Standard Postgres tables; the primary two-way sync target for app data.	⇄	Quotes Pricing documents with line items.

How the Postgres Heroku and Vtiger CRM connectors work

Postgres Heroku

Integration surface: SQL wire protocol (standard PostgreSQL)
Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required
Change detection: Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
Capabilities: read · write
Rate limits: No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan

Vtiger CRM

Integration surface: REST API
Authentication: HTTP Basic with username and access key
Change detection: Polling on record modified timestamps; workflows can fire outbound HTTP calls on record events
Capabilities: read · write · webhooks
Rate limits: Subject to the platform's API rate limits, which vary by edition.
