Get exchange rates in Zapier with Webhooks by Zapier
Build a Zap that fetches current FX rates with Webhooks by Zapier, maps the JSON fields, and sends the observation to a spreadsheet, CRM, or notification.
Use a GET request in Webhooks by Zapier and ask for every needed currency in one symbols parameter. Webhooks by Zapier is a Premium app on Zapier’s current plan list. Test anonymously first, then store the bearer key in Zapier’s authentication fields instead of placing a secret in a URL or a visible step.
/v1/latest/USD?symbols=EUR,GBP,JPY.rates.EUR, source, market_session, and data_updated_at into later steps.Create the trigger and webhook step
Start with the trigger that should refresh the rate—Schedule by Zapier, a form submission, or an event from another app. Add Webhooks by Zapier → GET, then use the URL below. One request can return all currencies your next step needs.
Add authentication without exposing a key
For the first test, leave authentication empty and inspect the response. For a keyed Zap, configure the request header Authorization with the value Bearer {{your_key}} through Zapier’s supported authentication or custom-header fields. Never paste a production key into a public URL, a shared screenshot, or a sample Zap.
Map the response into the next action
After Test step, Zapier exposes nested fields from the JSON response. Map rates.EUR or another requested symbol into the destination, and keep source, market_session, and data_updated_at alongside it. Those fields tell a downstream report why a value may be daily rather than intraday.
- Spreadsheet: write the rate, base, quote, and observation time to one row.
- CRM or invoice draft: use the rate for an estimate, then let the payment provider determine settlement.
- Notification: include the source and timestamp so the message is not mistaken for a live dealing quote.
Choose a schedule and handle failures
A daily report needs one scheduled call; an hourly dashboard uses about 720 calls in a 30-day month. Keep all symbols in one request. If Zapier receives 401, fix authentication. If it receives 429, reduce the schedule or account for the plan limit instead of creating an immediate retry loop.
