# Signing with NOM 151

The NOM 151 feature can be used through both the Dropbox Sign website and with several API endpoints. Once you have enabled the feature (please see our Setup section for more information), the option will be available in the Dropbox Sign Website workflow and the parameter will be active for API users. Please see the steps below on how to sign with NOM 151 enabled.

| -------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| 1. Create a non-embedded signature request.                                                                                                                          | Use one of these endpoints: <ul><li>/v3/signature\_request/send</li> <li>/v3/signature\_request/send\_with\_template</li></ul> |
| 2. Add the <code>certification\_types</code> parameter to your signature request, with the <code>"nom\_151":true"</code> option. Send the request for signature.     | <img src="https://files.buildwithfern.com/https://dropbox123432.docs.buildwithfern.com/b479204bf70bda043ef7e7f62238426bfc21ab8e917c737c948847c59edbcd05/docs/nom-151/nom-151-non-embedded-2.png" alt="Image of application/json code example" />                           |

## Embedded Requesting Workflows

| Steps                                                                                                                                                                        | Images                                                                                                                                             |
| ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- |
| 1. Set up an embedded unclaimed draft signature request. See the embedded request walkthrough for details.                                                                   | Use one of these endpoints:<ul><li> /v3/unclaimed\_draft/create\_embedded</li> <li>/v3/unclaimed\_draft/create\_embedded\_with\_template</li></ul> |
| 2. When sending the initial API request, set the value of the <code>force\_signer\_roles</code> to <code>true</code>. This will enable the requester to see the signer step. | <img src="https://files.buildwithfern.com/https://dropbox123432.docs.buildwithfern.com/218a67ec94c7f7d08a0abdc733e48c2726a010ed3f7cb79fb57660b3a81f1f14/docs/nom-151/nom-151-embedded-2.png" alt="Image of application/json code example" />                                               |
| 3. When the Sender is assigning a Signer, the option to select "<strong>NOM 151</strong>" will be present. Check the checkbox.                                               | <img src="https://files.buildwithfern.com/https://dropbox123432.docs.buildwithfern.com/b77d164eb25de292d59a78d4ec474fe781a8050608ce5256b2dfb92af0ebf468/docs/nom-151/nom-151-embedded-3.png" alt="Image of Admin Console navigation link in settings" />                                   |
| 4. Complete the remaining steps to send your signature request. Follow steps 3-5 of the "<strong>Non-embedded workflows</strong>" section above to view your certificate.    | <img src="https://files.buildwithfern.com/https://dropbox123432.docs.buildwithfern.com/c64e298f974813d968d8dce03fb123901de84393aa1e9d552029a52a5bdcd338/docs/nom-151/nom-151-embedded-4.png" alt="Image of NOM 151 option selected" />                                                     |

## FAQ

<AccordionGroup>
  <Accordion title="Can NOM 151 be used with eID?">
    Yes, both eID and NOM 151 can be used for the same signature request. First eID verification will be completed and then the signature request will be sent for NOM 151 certification.
  </Accordion>

  <Accordion title="How long does the NOM 151 certification process take?">
    The NOM 151 process can vary on how long it takes to process. The process to generate a certificate will not start until all signers have completed signing their portion of the document.

    In most cases, the certificate takes a few moments to be generated. Once completed, the "NOM 151" option will appear in the options dropdown for the signature request on the "Documents" tab of your account. Select this option to verify and download the certificate.

    If the document does not have the option to view the certificate after 24 hours, please [open a request](https://faq.hellosign.com/hc/en-us/requests/new) with our Sign API support team and provide the signature request ID for further troubleshooting.
