Square to Postgres integration for a queryable payments replica
The Square to Postgres integration from Adapters syncs payments, orders, refunds, customers, and payouts from the Square API into your own Postgres tables on an incremental schedule, so reporting and app features query transaction data with plain SQL instead of paging the Square API live. Field mapping takes about a minute and no code is required.

What running Square to Postgres by hand costs you
- Square reports cannot join to your product, inventory, or accounting tables, so cross-location margin and cohort questions get answered by exporting CSVs.
- The Square API pages with cursors and returns money as integer cents in a nested money object, so a hand-rolled export mishandles multi-location and currency every time.
- Payments get refunded and disputed after they settle, and a one-time export into Postgres is stale before the next payout reconciliation.
The field mapping, out of the box
These cables are pre-wired when you pick the pair. Rewire any of them, or add your own, in the same visual data mapping tool you use for every adapter.
Input / SQUARE
Output / POSTGRES
Transforms included
Incremental loads walk the Square cursor and filter on the updated-at range so only changed payments come back; the nested total_money object flattens to an integer cents column plus a currency code, buyer and location ids land as foreign keys, the RFC 3339 timestamps parse to TIMESTAMPTZ in UTC, and writes upsert with ON CONFLICT on the Square payment id so a retried or overlapping window never double-inserts a row.

Square to Postgres sync: common questions
How does the Square to Postgres sync work?
The Square to Postgres integration from Adapters syncs payments, orders, refunds, customers, and payouts from the Square API into your own Postgres tables on an incremental schedule, so reporting and app features query transaction data with plain SQL instead of paging the Square API live. Field mapping takes about a minute and no code is required.
How much does the Square Postgres integration cost?
Pricing is flat and monthly: Starter at $49, Growth at $149, Scale at $399. Every plan includes this pair, visual field mapping, and per-record logs. There are no per-task or per-row fees, so the bill stays the same as volume grows.
How often can Adapters sync Square to Postgres?
Hourly on Starter, every 5 minutes on Growth, and down to every minute on Scale. Failed records retry automatically with backoff, and alerting plus a full per-record log come standard on every run.
Do I need to write code to connect Square and Postgres?
No. Fields are auto-mapped the moment you pick the pair, and you can rewire any mapping visually before the first sync. Incremental loads walk the Square cursor and filter on the updated-at range so only changed payments come back; the nested total_money object flattens to an integer cents column plus a currency code, buyer and location ids land as foreign keys, the RFC 3339 timestamps parse to TIMESTAMPTZ in UTC, and writes upsert with ON CONFLICT on the Square payment id so a retried or overlapping window never double-inserts a row.
