# Request and manage e-signatures

> Send Dataroom documents for legally binding e-signatures, track signer progress, and access the cryptographic seal hash on completion.

Launchboard's e-signature workflow lets you collect legally binding signatures on documents stored in your Dataroom. Signers receive an email with a signing link — no Launchboard account required — and you can track each signer's progress in real time from the Inspector panel. Once all signers complete, the signed PDF is stored as an immutable version and a cryptographic seal hash is computed as permanent proof.

## Requesting signatures

<Steps>
  <Step title="Open the document in the Dataroom">
    Navigate to **Dataroom** and click on the document you want to send for signatures. The document must have a status of `REVIEWED` or later.
  </Step>

  <Step title="Click Request Signatures">
    In the Inspector panel or the document toolbar, click **Request Signatures**. A dialog opens where you configure the signature request.
  </Step>

  <Step title="Add signers">
    Enter the name and email address of each person who needs to sign. You can add multiple signers — each will receive a separate signing link.
  </Step>

  <Step title="Configure signature fields">
    Position signature fields and any other fields (date, initials) on the document. Each field is assigned to a specific signer.
  </Step>

  <Step title="Send the request">
    Click **Send**. Launchboard sends each signer an email with a unique link to sign the document. The document status moves to `PENDING_SIGNATURE`.
  </Step>
</Steps>

## The signing experience

Signers receive an email with a link to a Launchboard signing page (`/sign/...`). They can open the document, review it, and apply their signature — no Launchboard account is required to sign. Once a signer completes their signature, their status updates in the Inspector immediately.

If a signer needs to return to a partially completed document, you can click **Resume signing** in the Inspector to send them a new link, or use **Copy signing link** to share it directly.

## Signature status tracking

| Status              | Meaning                                             |
| ------------------- | --------------------------------------------------- |
| `PENDING_SIGNATURE` | Request sent — no one has signed yet                |
| `PARTIALLY_SIGNED`  | One or more signers have completed, others have not |
| `SIGNED`            | All signers have completed the document             |

## What happens on completion

When the last signer completes the document:

1. The fully signed PDF is downloaded and stored as a new immutable version in the Dataroom.
2. A **seal hash** is computed from the signed PDF and stored alongside the version record.
3. The original unsigned version remains intact — no existing versions are overwritten.
4. The document status moves to `SIGNED`.

The signed version becomes the default when you preview or download the document.

## Seal hash

<Note>
  The seal hash is the cryptographic proof that a specific version of a document was signed. It is a SHA hash computed from the signed PDF at the moment of completion. If the document is altered in any way after signing, the hash will not match — making tampering detectable.
</Note>

To find the seal hash for a signed document:

1. Open the document in the Dataroom.
2. In the **Inspector** panel, scroll to the **Signatures** section.
3. The seal hash is displayed in a truncated format. Click the **copy** icon to copy the full hash to your clipboard.

You can share the seal hash with investors, counsel, or auditors as proof of the document's integrity.

## Status and event mapping

Launchboard listens for events from the e-signature provider and maps them to document statuses automatically:

| Provider signal                                                 | Document status     |
| --------------------------------------------------------------- | ------------------- |
| `document.sent`, `document.pending`, `envelope.sent`            | `PENDING_SIGNATURE` |
| `recipient.signed`, `recipient.completed` (partial progress)    | `PARTIALLY_SIGNED`  |
| `document.completed`, `envelope.completed` (all signers done)   | `SIGNED`            |
| `document.cancelled`, `document.rejected`, `envelope.cancelled` | `REVIEWED`          |

## Reconciliation

Launchboard uses webhooks to receive signature updates in real time. If a webhook is missed or delayed, the status in the Inspector may be temporarily out of date. To pull the latest status manually, click **Sync now** in the Inspector's Signatures section. Launchboard will fetch the current state from the signing provider and update the document status.

## Cancelling a signature request

To cancel an in-progress signature request, open the Inspector and click **Cancel request** in the Signatures section. The signature request is cancelled and the document returns to `REVIEWED` status. If some signers had already completed before the cancellation, those signatures are voided.
