# Getting started

## Overview

Gasless transactions can be utilized outside of the mobile device such as from a backend, web dapp, desktop, etc. Submitting transactions is a 2 step process: 

1. Sign a transaction on the client (web, backend, etc)
2. Create a HTTP request containing a JSON payload with details about the transaction you'd like to relay. 

## Get an API key for gasless transactions

An API key is required to use the infrastructure to power gasless transactions. Visit  <https://app.rallyprotocol.com/> to generate both Amoy and Mainnet Polygon API keys.&#x20;

## Using an existing Gas Station Network Client Library.

Our hosted transaction infrastructure honors the [Gas Station Network](https://opengsn.org/) interface with the addition of an authentication HTTP header containing your API key. If you're already using a GSN client the following steps should be all you need to change:&#x20;

1. Set `https://api.rallyprotocol.com` as your relay URL.&#x20;
2. Add the following header to the HTTP request `Authorization: Bearer <YOUR_API_TOKEN>`&#x20;

## Submitting Requests Without a GSN Library

*Examples coming soon. Reach out to us on* [*Discord*](https://discord.gg/rlynetwork) *and we'll happily walk you through it*
