# Step 1 - Choose Product & Validity
This is the first screen you see after clicking New Certificate in the CERTInext portal. You choose which type of certificate you want and for how long.
#### Field Reference
• Group: The name of your organisation as registered in CERTInext. This is set by your administrator. This field is auto-filled. No action needed.
• CA Source (\*): The Certificate Authority that will issue your certificate. 'eSign' is eMudhra's CA for S/MIME certificates. Select 'eSign' from the dropdown.
• Certificate Type (\*): The category of certificate you are applying for. Select 'S/MIME Certificates' from the dropdown.
• Product (\*): The specific S/MIME product variant and its validity period. Select 'eSign - SMIME - Simple MV-S 1 Year' (or the product your administrator has assigned to your group).
• Cost: The price of the selected product in USD, as charged to your organisation's credit balance. This updates automatically when you select a product. No action needed. Verify the amount is correct.
• Product Info Box: A summary of what S/MIME certificates provide: email validation, digital signing, and encryption. Read this to confirm S/MIME is the certificate type you need.
**NOTE:** Fields marked with an asterisk (\*) are mandatory. You cannot proceed to the next step without filling them in.
**TIP:** If you do not see the product you need in the dropdown, contact your CERTInext administrator; they control which products are available to your group.
#### What to Do
• Click New Certificate in the left sidebar (or top menu) to begin.
• Confirm that Group shows your correct organisation name.
• Set CA Source to eSign.
• Set Certificate Type to S/MIME Certificates.
• Select the correct Product from the dropdown. The cost will appear automatically.
• Review the feature list in the blue information box to confirm your selection.
• Click Next to proceed to Step 2.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.certinext.io/documentation/certificate-lifecycle-management/ordering-a-certificate/as-a-customer/ordering-smime-certificates/phase-1-steps/step-1-choose-product-and-validity.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
