   * No. For systems using Amazon Services, there will be no integration and you will need to switch to using Postman.

2. **Can Postman be configured to only send SMSes during whitelisted hours?**
   * Postman will send out SMSes once we have received the API call, a scheduling feature is not available.

## 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://postman-v2.guides.gov.sg/faq/postman-v2-sms-api-faq/integration-and-configuration-related-inquiries.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.
