<mark style="color:green;">`POST`</mark> `https://api.zapsign.com.br/api/v1/models/{{original_doc_token}}/upload-extra-doc/`

This endpoint allows you to add attachments to your original document via [**Dynamic Template**](https://clients.zapsign.com.br/en/help/templates)**.** Its possible to add up to 14 extra docs (one at a time, therefore, one request for each attachment), counting the original doc your signer will be able to sign 15 documents at once.

{% hint style="info" %}
**Obs:** dont mistake the extra document with [the batch sign via API](https://docs.zapsign.com.br/english/signatarios/assinar-em-lote-via-api), because this one is made to sign multiple documents at the same time not to create attachments. They have different use cases.

### Frequently asked questions

#### Whats an attachment/extra document?

In case you use our web platform, you will notice that is possible to upload multiple PDFs at once to be signed by the same signers:

<figure><img src="https://1401277393-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M4noMoX5ZGb2-RhWjjf-1703796690%2Fuploads%2FM9fXzN0tnuekFrJkI9H4%2Fimage.png?alt=media&#x26;token=6295c788-011e-4822-9263-bdeacb83c64a" alt=""><figcaption><p>Example of the web application with 3 PDFs in one envelope.</p></figcaption></figure>

That way, when the signer is going to sign the document, she will be see all of them, to sign at once:

<figure><img src="https://1401277393-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M4noMoX5ZGb2-RhWjjf-1703796690%2Fuploads%2FvwNqxS0BPMGYUbZfR9Fz%2Fimage.png?alt=media&#x26;token=18897b64-abc1-442b-8ad0-f68a8a2f11cd" alt=""><figcaption></figcaption></figure>

**The original document will be the number 1** and the **attachments will appear to the signer as the documents number 2,3, etc**. Doing a GET request on the original document, the attachments will be on the **"extra\_docs"** paramenter.

**Can i place signatures on an attachment?**\
Yes! Just send yout attachment token on the [endpoint for placing signatures](https://docs.zapsign.com.br/english/documentos/opcional-posicionar-assinaturas)

**I've added attachment by mistake. Can i delete it?**\
No. For now, it's impossible to remove attachments after added. You can [delete de document](https://docs.zapsign.com.br/english/documentos/excluir-documento) and [re-create it](https://docs.zapsign.com.br/english/documentos/criar-documento).
