Cin7 to Postgres Heroku integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Cin7 and Postgres Heroku: authenticate both systems, choose the objects to sync (such as Cin7's Inventory levels and Sales orders), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Postgres Heroku side: JSONB Columns, Sequences, Follower Databases, Tables, plus custom fields where Postgres Heroku exposes them. On the Cin7 side: Stock adjustments and transfers, Credit notes / returns, Products, Inventory levels. Stacksync auto-detects both schemas and converts types between the two systems.

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 Cin7 and Postgres Heroku: Read ERP records with a query; Internal tools and automations without API code; React to ERP changes. Records from Cin7 live in Postgres Heroku as ordinary tables or collections, joinable with the rest of your data.

Cin7: REST API; note that Cin7 Omni and Cin7 Core (formerly DEAR Systems) are separate products with separate APIs. Authentication: API key credentials (paired with a username or account ID, depending on the product). Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. Stacksync manages authentication, retries, and rate limits on both sides.

Postgres Heroku: Heroku Postgres is standard PostgreSQL, so any Postgres client, driver, or SQL tool connects unchanged. Cin7: Cin7 is two distinct products under one brand: Cin7 Omni and Cin7 Core (the former DEAR Systems), each with its own API, credentials, and object shapes, so a connector must target the right one. Stacksync's field mapping accounts for these differences between Cin7 and Postgres Heroku without custom code.
