# Craft Clawback (Beta)

> Reclaim tokens from an unclaimed Send invite before it expires.

This guide walks through crafting a Clawback transaction using the `/send/v1/craft-clawback` endpoint. You will load an existing invite code, derive the Program Derived Address (PDA), POST to the endpoint, then sign with the sender keypair to reclaim unclaimed tokens.

## Overview

<Steps>
  <Step>
    Load invite code.
  </Step>

  <Step>
    Load public key from invite.
  </Step>

  <Step>
    Find the [Program Derived Address (PDA)](https://solana.com/core/pda) of the invite.

    * Uses `"invite"` and the public key of recipient at seed.
  </Step>

  <Step>
    Post request to get Clawback transaction.
  </Step>

  <Step>
    Sign with sender keypair, then send transaction and wait for confirmation.
  </Step>
</Steps>

## Invite Code and Public Key

```js theme={null}
// STEP 1: Load invite code
const invite_code = process.env.INVITE_CODE;

// STEP 2: Load the public key from the invite code
const secret_key = invite_code_to_priv_key(invite_code); // Follow the utils.js guide
const pubkey = Keypair.fromSecretKey(secret_key).publicKey;
```

## Invite PDA

```js theme={null}
// STEP 3: Find the Program Derived Address (PDA) for the invite
// Uses `"invite"` as seed + the public key
// PDAs are deterministic addresses owned by the program
const invite_pda = PublicKey.findProgramAddressSync(

  )[0];
```

## Craft Clawback

<Info>
  **NOTE**

  The clawback will return the full amount including leftover transaction fees and/or rent back to the sender.
