# Dispatch Transaction

Wander Injected API dispatch() function

The `dispatch()` function allows you to quickly sign and send a transaction to the network in a bundled format. It is best for smaller datas and contract interactions. If the bundled transaction cannot be submitted, it will fall back to a base layer transaction. The function returns the [result](#dispatch-result) of the API call.

| Argument      | Type                                                                    | Description                                                  |
| ------------- | ----------------------------------------------------------------------- | ------------------------------------------------------------ |
| `transaction` | [`Transaction`](https://github.com/arweaveTeam/arweave-js#transactions) | A valid Arweave transaction instance (**without a keyfile**) |

{% hint style="info" %}
**Note:** This function requires the [`DISPATCH`](/api/connect.md#permissions) permission.
{% endhint %}

{% hint style="warning" %}
**Note:** If you are trying to sign a larger piece of data (5 MB <), make sure to notify the user to not switch / close the browser tab. Larger transactions are split into chunks in the background and will take longer to sign.
{% endhint %}

{% hint style="warning" %}
**Note:** The function uses the default bundler node set by the user or the extension. Consider using the [`signDataItem()`](/api/sign-dataitem.md) function to submit data to a custom bundler.&#x20;
{% endhint %}

## Dispatch result

The `dispatch()` function returns the result of the operation, including the ID of the submitted transaction, as well as if it was submitted in a bundle or on the base layer.

```ts
export interface DispatchResult {
  id: string;
  type?: "BASE" | "BUNDLED";
}
```

## Example usage

```ts
import Arweave from "arweave";

// create arweave client
const arweave = new Arweave({
  host: "ar-io.net",
  port: 443,
  protocol: "https"
});

// connect to the extension
await window.arweaveWallet.connect(["DISPATCH"]);

// create a transaction
const transaction = await arweave.createTransaction({
  data: '<html><head><meta charset="UTF-8"><title>Hello permanent world! This was signed via Wander!!!</title></head><body></body></html>'
});

// dispatch the tx
const res = await window.arweaveWallet.dispatch(transaction);

console.log(`The transaction was dispatched as a ${res.type === "BUNDLED" ? "bundled" : "base layer"} Arweave transaction.`)
```

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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.arconnect.io/api/dispatch.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
