Pre-requisites

  • You have an active Conduit account with API access
  • You have API credentials (API Key and Secret)
  • You have reviewed our Customers Core Concepts
In this guide, you’ll create your first fiat conversion — exchanging one fiat currency for another (e.g., USD → EUR) and paying a destination bank account.
1

Create a quote

Use the /quotes endpoint to get a locked rate for your source and target currencies.

​
Request Example

curl --request POST \
  --url https://api.conduit.financial/quotes \
  --header "X-API-Key: your_api_key" \
  --header "X-API-Secret: your_api_secret" \
  --header "Content-Type: application/json" \
  --header "Api-Version: 2024-12-01" \
  --data '{
    "source": {
      "asset": "USD",
      "amount": "1000.00"
    },
    "target": {
      "asset": "EUR"
    }
  }'

​
Response Example

{
  "id": "quote_34LGFxjgPBqCwLXBX1AD1D8SXvv",
  "source": {
    "amount": "1000.00",
    "asset": "USD"
  },
  "target": {
    "amount": "915.00",
    "asset": "EUR"
  },
  "createdAt": "2025-10-27T00:00:00.000Z",
  "expiresAt": "2025-10-27T00:03:00.000Z"
}
Save the quote_id; you will need it when creating the transaction.
2

Create a fiat conversion transaction

Use the /transactions endpoint with type: conversion and the quote.

​
Request Example

curl --request POST \
  --url https://api.conduit.financial/transactions \
  --header "X-API-Key: your_api_key" \
  --header "X-API-Secret: your_api_secret" \
