# Send Transaction

{% hint style="info" %}
Use this endpoint after you sign an unsigned XDR returned by another endpoint.
{% endhint %}

### What it does

This endpoint submits a signed Stellar transaction to the network.

Typical flow:

1. Call an endpoint that returns `unsignedTransaction`.
2. Sign that XDR with the user wallet.
3. Submit the signed XDR here.

### Headers

### API reference

## Submit a client-signed XDR to the Stellar network

> Forwards the signed transaction to Horizon, then polls the Soroban RPC to enrich the response with on-chain metadata. The response has three mutually-exclusive shapes:\
> \
> &#x20; \- Plain contract call (fund, release, approve, dispute, etc.): \`{ txHash, ledger, code: "STELLAR\_TX\_SUBMITTED", message }\`.\
> &#x20; \- Factory deploy (success): \`{ txHash, ledger, contractId, escrow }\` with the freshly-indexed snapshot — no \`code\`/\`message\`.\
> &#x20; \- Factory deploy (indexer lagging): \`{ txHash, ledger, code: "STELLAR\_TX\_SUBMITTED\_INDEXER\_LAGGING", message }\` — the tx is in the ledger; retry \`getTransaction(txHash)\` shortly to recover the contract address.\
> \
> Clients should branch on \`code\` when present, otherwise on the existence of \`contractId\`. The \`code\` is stable; the \`message\` is free text and subject to change.

### Response

This endpoint returns the submitted transaction result from the Stellar network.

### Example

{% code title="send-transaction.ts" lineNumbers="true" %}

```typescript
import axios from "axios";

const http = axios.create({
  baseURL: "https://dev.api.trustlesswork.com",
  timeout: 10000,
  headers: {
    "Content-Type": "application/json",
    "x-api-key": your_api_key,
  },
});

export const useExample = async () => {
  // Get the signer address
  const { address } = await kit.getAddress();

  const response = await http.post("/any-endpoint", {
    // body requested for the endpoint
  });

  // Get the unsigned transaction XDR
  const { unsignedTransaction } = response.data;

  // Sign the transaction with the wallet
  const { signedTxXdr } = await signTransaction(unsignedTransaction, {
    address,
    networkPassphrase: WalletNetwork.TESTNET,
  });

  // Submit the signed transaction
  const tx = await http.post("/stellar/send-transaction", {
    signedXdr: signedTxXdr,
  });

  return tx.data;
};
```

{% endcode %}

### Notes

* Pass the signed XDR in the `signedXdr` field.
* Use the same network passphrase used to build the transaction.
* This step usually comes right after a create, update, fund, or release call.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.trustlesswork.com/trustless-work/v2-en/api-rest/stellar/send-transaction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
