We have prepared one demo hotel where you can fetch availability and create reservations. You can use the following information to access it: * **API base url** - `https://api.mews-demo.com` * **Hotel Id** - `3edbe1b4-6739-40b7-81b3-d369d9469c48` * **Configuration Id** - `93e27b6f-cba7-4e0b-a24a-819e1b7b388a` You will also have access into the system so it is possible for you to check whether the reservations sent to the API are correctly posted to the system. To sign in to the Mews system, use the following credentials: * **Mews applications base url** - `https://app.mews-demo.com` * **Email** - `distributor-api@mews.li` * **Password** - `Distributor-api1` ## Production environment This is the live production environment. * **API base url** - `https://api.mews.com` * **Mews applications base url** - `https://app.mews.com` * **Hotel Id** - This depends on the hotel and should be provided to you by the hotel administrator. * **Configuration Id** - This depends on the hotel setup and can be found in **Mews Operations** administration. ## IP address allowlisting Allowlisting (formerly 'whitelisting') is a common security measure which can be applied to a system to allow only specified external systems to talk to it. This has traditionally been achieved using IP address-based firewall rules. However, this approach does not work with modern cloud based architectures, which use dynamic and shared IP addresses, proxy servers and elastic resources. For this reason, we do not support the use of IP address allowlists for our APIs and we cannot supply a list of IP addresses for our APIs. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.mews.com/booking-engine-guide/booking-engine-api/guidelines/environments.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.
