Sync Ramp transactions to Google Sheets automatically

Build me a deterministic code workflow that mirrors every new Ramp card transaction into a Google Sheet, one row per transaction. No reasoning, no LLM calls, just a fixed mapping from Ramp fields to sheet columns.

Trigger: Ramp poll trigger on the Card Transaction event. Fire once per new transaction.

For each new transaction:

1. Call Ramp Get Transaction with the transaction id from the trigger payload to expand any fields the poll payload doesn't include (memo, receipts, accounting category and sync status, department, cardholder details, policy flags).

2. Call Google Sheets Append Values on a configured spreadsheet id and tab name with a single row. Use USER_ENTERED so dates and amounts render correctly.

Columns to append, in this order: transaction date, posted date, amount in USD (convert from Ramp's cents to dollars), merchant name, MCC category, cardholder name, cardholder email, department, memo, receipt attached (yes/no based on whether any receipts are present), policy flags (comma-separated if multiple), accounting sync status, Ramp transaction id, and a link back to the transaction in Ramp (https://app.ramp.com/transactions/<transaction_id>).

Configurable inputs the user should set when installing: Google spreadsheet id, sheet/tab name, and an optional set of filters (entity, department, minimum amount). Default behavior with no filters is to sync everything.

Notes for the build: Ramp transaction amounts are CurrencyAmount objects in cents; divide by 100 for the USD column. Append, do not overwrite, so existing rows and downstream pivots stay intact. Assume a header row already exists in the target tab matching the column list above; do not write the header.

Additional information

What does this prompt do?

Watches Ramp for new card transactions and adds one row per transaction to a Google Sheet you choose.
Pulls the full transaction details so each row includes memo, receipt status, accounting category, and policy flags, not just the basics.
Keeps a clean, queryable ledger your finance team can pivot, filter, or feed into BI tools without logging into Ramp.
Runs in the background on a fixed mapping, so every column lines up the same way every time.

What do I need to use this?

A Ramp account with permission to read transactions, memos, receipts, and accounting data.
A Google account with edit access to the Google Sheet you want to use as the ledger.
A spreadsheet and tab name picked out, with a header row that matches the columns below.

How can I customize it?

Change which columns get written, or reorder them, to match how your finance team likes to slice the data.
Filter the transactions you sync, for example only one entity, one department, or transactions over a certain amount.
Point it at a different spreadsheet or tab per business unit so each team owns their own ledger.

Frequently asked questions

Will this overwrite my existing Google Sheet?

No. New transactions are appended below the last row. Anything already in the sheet stays put, including pivots and formulas built off the data.

How quickly do new transactions show up in the sheet?

Ramp is checked on a recurring schedule, so a new card swipe typically lands in the sheet within a few minutes of Ramp recording it.

What if a transaction is updated after it syncs, like a memo or receipt added later?

By default each transaction is written once when it first appears. If you want updates reflected too, you can extend the workflow to refresh existing rows when a transaction changes.

Can I split transactions across multiple tabs or sheets?

Yes. You can route by department, entity, cardholder, or any other Ramp field to a different tab or even a different spreadsheet.

Do I need to be on a paid Ramp plan?

You need a Ramp plan that lets you connect to their developer access, which is available on standard Ramp accounts. No extra subscription is required on the Google Sheets side.
