# Request Transaction Data

{% openapi src="<https://api.swaggerhub.com/apis/dinngodev/Protocolink/1.0.0/swagger.json>" path="/v1/transactions/build" method="post" %}
<https://api.swaggerhub.com/apis/dinngodev/Protocolink/1.0.0/swagger.json>
{% endopenapi %}

Provides the transaction request that needs to be sent, comprising the Router contract `address` (to), transaction `data` (data), and the amount of ETH to be carried in the transaction (value).

```javascript
const getRouterTransactionRequest = async (routerData) => {
  const result = await client.post("/v1/transactions/build", { body: routerData });
  return result.data;
};

const routerData = {
  chainId: 1,
  account: USER_ADDRESS,
  logics: [swapLogic, supplyLogic],
  // If the estimate result returns permitData, the user should sign the permitData,
  // and return the signed permitSig along with it.
  permitData: permitData,
  permitSig: permitSig,
  // If there is only one referral address, you can use the 'referral' property.
  // If there are multiple referral addresses, use 'referrals' and specify the rates accordingly.
  referral: collector,
  referrals: [
    { collector: collector, rate: 5000 },
    ...
  ]
};

const transactionRequest = await getRouterTransactionRequest(routerData);
```

The result contains a list of chains that looks the following:

```json
{
  "to": "0xDec80E988F4baF43be69c13711453013c212feA8",
  "data":
