# How do I get fund or ETF data by ISIN in Zapier or Make?

**Short answer:** In Zapier the "Webhooks by Zapier" action and in Make the "HTTP → Make a request" module send the GET with a bearer header; no custom app is needed. A fund never loaded before loads on demand and can exceed a no-code default timeout, so raise it where the tool allows or re-run the step once. The request is GET https://fundfactsapi.com/api/v1/funds/{isin} with the header Authorization: Bearer <your key>; read name, data.headlineMetrics.ter, data.riskRating, data.topHoldings and data.dataAsOf from the JSON. A free key (5 lookups a month, no card) is enough to try it.

In Zapier the "Webhooks by Zapier" action and in Make the "HTTP → Make a request" module send the GET with a bearer header; no custom app is needed. A fund never loaded before loads on demand and can exceed a no-code default timeout, so raise it where the tool allows or re-run the step once.

## What you need

- An API key from [fundfactsapi.com/signup](https://fundfactsapi.com/signup). The Free plan is 5 lookups a month and asks for no card. Keys start with `ffk_`.
- The ISIN of the share class you want. Every share class has its own ISIN; `GET /search?q=` turns a name into ISINs and is free.
- Both tools have a generic HTTP step; no custom app is needed. The steps below use Zapier's "Webhooks by Zapier" action, and Make's "HTTP → Make a request" module takes the same values.

## The code

```text
Zapier
1. Trigger: whatever brings you an ISIN (a new Airtable record, a form, a Sheets row).
2. Action: Webhooks by Zapier → Custom Request
     Method   GET
     URL      https://fundfactsapi.com/api/v1/funds/{{isin}}
     Headers  Authorization: Bearer ffk_...   (paste your key)
3. Use the fields Zapier extracts from the JSON in later steps:
     name, data__headlineMetrics__ter, data__riskRating, data__keyFacts__aum,
     data__profile__category, data__topHoldings__0__name, data__dataAsOf

Make
1. HTTP → Make a request
     URL            https://fundfactsapi.com/api/v1/funds/{{isin}}
     Method         GET
     Headers        Authorization = Bearer ffk_...
     Parse response yes
     Timeout        300
2. Map data.headlineMetrics.ter, data.riskRating, data.topHoldings[] and
   data.dataAsOf into the next module (Sheets, Airtable, Notion, e-mail).
```

## What comes back

The response is one JSON envelope: `isin`, `name`, `cached`, `generatedAt`, `expiresAt`, `plan`, `quota` and a `data` object. Inside `data` you get `keyFacts` (asset class, currency, fund size, inception date, distribution policy, number of holdings), `headlineMetrics` (TER, AUM, 3-year volatility and Sharpe, yield to maturity and duration for bond funds), `riskRating` (the 1–7 KID indicator), `profile` (a rule-based classification: kind, category, risk band, region focus, sector tilt), `topHoldings`, `sector`, `geography`, `region`, `assetAllocation`, `creditQuality`, `maturity`, `calendarReturns`, `annualisedReturns`, `cumulativePerformance`, `indexedPerformance`, `metrics` (max drawdown, P/E, income yield…), `sfdrArticle`, `costs` (PRIIPs entry, exit, ongoing, transaction and performance fees, reduction in yield) and `dataAsOf`, the date of the underlying figures.

Money and percentages arrive as the fund house prints them, as strings such as `"0.20%"` or `"USD 151.7bn"`. Breakdown weights and return series are plain numbers in percent. Fields that do not apply to the fund's asset class are empty strings, `null` or empty arrays, never missing keys; treat empty as "not disclosed", not as zero.

A trimmed example for iShares Core MSCI World UCITS ETF ([IE00B4L5Y983](https://fundfactsapi.com/funds/IE00B4L5Y983)):

## Things to know before shipping

**First call is slow, later calls are fast.** A fund never loaded before is read on demand from the documents the fund house publishes. That first call takes 15 seconds to about 3 minutes; set your client timeout to 300 seconds and do not fire a second request for the same ISIN while the first is running. Every later call returns from the store in well under a second with `cached: true`; past 24 hours the payload comes back flagged `stale: true` while a refresh runs in the background, and nothing older than 7 days is served without a new read.

**Requests are counted per ISIN.** One request is counted per fund found. `X-RateLimit-Remaining` on every response tells you how many are left this month; a `429 rate_limited` response carries `Retry-After`. Search and `/me` are free. Cache payloads by ISIN until `expiresAt` and you will rarely spend more than one request per fund per day.

**Batch when you have a list.** `POST /funds` with `{ "isins": [...], "wait": true }` answers up to 10 ISINs per call on Starter, 50 on Pro and 200 on Scale. ISINs still loading come back with `status: "pending"`; send them again a minute later.

**Not every ISIN is a fund.** A stock, bond or index ISIN returns `404 fund_not_found`. Validate the format first (12 characters, Luhn check digit) so a typo does not spend a request; the [ISIN validator](https://fundfactsapi.com/tools/isin-validator) shows the rule.

**Show the as-of date.** `data.dataAsOf` is the date printed on the fund's documents. Display it next to any figure.

## FAQ

### The step times out on the first run. Why?

A fund never loaded before is read on demand from the fund house's documents, which can take a minute or two, longer than some no-code default timeouts; a fund already in the store answers at once, even past its 24 hours (then with stale: true while it refreshes). Raise the timeout where the tool allows it, or re-run the step: the second call returns instantly from the store.

### Do I need a credit card to try it?

No. The Free plan is 5 lookups per month with no card; sign up with an e-mail address or Google and the key is shown in the dashboard.

### Which ISINs work?

Any share class of a UCITS fund, ETF, money-market fund or open-end fund whose management company publishes a product page, factsheet and KID. Each share class has its own ISIN and is looked up on its own. Stocks, bonds and indices are not funds and return 404 fund_not_found.

### How current are the figures?

Each ISIN is re-read from the fund house's documents at most every 24 hours; a request past that is answered at once from the store (stale: true) while the refresh runs in the background. data.dataAsOf is the as-of date printed on the documents, typically the last month end for a factsheet and the last trading day for holdings files.

## About FundFacts API

FundFacts turns any fund or ETF ISIN into one dated factsheet (fees and KID costs, the 1–7 risk indicator, holdings, sector and country exposure, returns) read from the fund house's own documents: as a client-ready PDF under your firm's name for advisers and wealth managers, as JSON through its API for developers, or inside ChatGPT and Claude through its MCP server.

FundFacts works inside ChatGPT and Claude as a connector (a remote MCP server): ask about any fund or ETF by ISIN, ticker or name and the assistant answers from FundFacts' dated figures, fees, risk, holdings, exposure and returns, with fund cards, side-by-side comparisons, holdings overlap and portfolio look-through.
