# I purchased a license about 3 months ago, but I did not add AMS at the time of purchase. Can I still buy the subscription?

You can purchase the AMS for your license at any time, but the AMS expiry date will be backdated to the time of the original license purchase.

For example, if you purchased your license in July, the AMS will also expire in July the following year, regardless of when it is purchased. Thus, it is more beneficial to purchase the AMS with your license and to renew it on time to be able to take full advantage of the subscription, when you need it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.apryse.com/support/faq/ams-add.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
