# List customers with renewals in the next N days

As a Reseller you list or export companies whose license renewal date falls within the next N days (e.g. 90 days) for renewal forecasting and sales follow-up. Use a credential with Client Role = **Reseller**. Call company search with a **`filter`** on renewal date (e.g. renewal date between today and today + N days) if the API supports it; otherwise export the full list and filter by the renewal date column client-side. Request body: see Endpoints → **Company** for filter structure and supported fields.

***

## POST /api/companies/search

Returns a paginated list of companies. Use **`filter`** to restrict results to companies whose **renewal date** is within the next N days (e.g. next 90 days). If the API supports a renewal-date filter, set the filter accordingly; otherwise use **`orderBy: "RenewalDate"`** and **`ascending: true`** and paginate to get upcoming renewals first, then filter client-side by date range.

> Retrieves a list of all companies. Use filter on renewal date (or orderBy RenewalDate) to list customers with renewals in the next N days.

## POST /api/companies/search/export

Exports the company list to CSV or Excel. Apply the same filter (or orderBy) as in search so the file contains only companies with renewals in the target window, or export all and filter by the renewal date column in your spreadsheet.

## 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://doc.keepnetlabs.com/api-reference/reseller/billing/list-customers-with-renewals-in-next-n-days.md?ask=<question>&goal=<endgoal>
```

`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.
