Use webhooks or the Synci API to transfer your data anywhere.

Developers

The Synci API is a powerful, REST-based interface designed for developers to automate their financial workflows. Whether you're building custom reporting, integrating with unique budgeting tools, or creating complex automation rules, our API provides the same robust features that power the Synci dashboard.

Webhooks allow your own applications or third-party services like Zapier to receive real-time notifications whenever something happens in your Synci account. Instead of polling our API for updates, Synci "pushes" the data to your URL as it occurs.

Guide for connecting Google Sheets to Synci. With Google Sheets, Synci mirrors your transactions and balances straight into a spreadsheet you own and control.

Google Sheets

Synci works as a SimpleFIN data source, so any SimpleFIN-compatible budgeting or finance app can pull your bank transactions and balances from Synci. It covers European banks (via GoCardless) and New Zealand banks (via Akahu), so you can use SimpleFIN with banks that other SimpleFIN providers don't reach.

Account

When you connect a third-party app with Synci or link an AI assistant through MCP, you decide what it can access, you can see everything you've connected in one place, and you can cut off access instantly. This article covers the consent screen, per-account access, where connections live, and the notifications you'll get.
