# Retrieve Launch PSBT

{% hint style="info" %}
An API Key is required to interact with Launchpad APIs. Please contact us to get an API Key and get started.
{% endhint %}

Use this endpoint to retrieve the PSBT. If PSBT is not ready a pending status will be returned. When the psbt is ready, the psbt to be signed is returned along with a pending confirmation status.

The PSBT needs to be signed by the wallet that owns all the pre inscribed inscriptions.

### `POST` /launchpad/get-launch-psbt/:launchpadId

<mark style="color:green;">`GET`</mark> `https://api.ordinalsbot.com/launchpad/get-launch-psbt/:launchpadId`

API Key is required in the header:

`headers: { 'x-api-key': '<YOUR_API_KEY>', ...otherHeaders }`

{% tabs %}
{% tab title="200: OK " %}

```json
// Response has the unsigned psbt and the status
// status is pending while the psbt is being created
// Once psbt is ready status will change to pending confirmation
 
{
  "status": "pending_buyer_confirmation",
  "psbt": "cHNidP8BAHECAAAAAfPQ0OTWpSxwRJK..."
}

```

{% endtab %}

{% tab title="500: Internal Server Error " %}
