Properties within the environment are based in the Netherlands and accept `EUR` currency. * **Platform address** - `https://api.mews-demo.com` * **Reservation push endpoint** - see [Mews: Process group](/channel-manager-api/mews-operations/reservations.md#process-group) * **Client Token** - will be provided by Mews upon request * **Connection Token** - will be provided by Mews upon request * **Test property** - user credentials will be provided by Mews upon request Test properties are configured to accept the following test credit cards: #### Test credit cards * Expiration date: *08/2021* or *10/2022* * Card holder name: any value is accepted * CVV: any value except for `000` is accepted * Card types and numbers: * Visa: 4111111111111111 * MasterCard: 5555444433331111 * Amex: 370000000000002 * Diners: 36006666333344 * Discover: 6445644564456445 ### Production environment * **Platform address** - `https://api.mews.com` * **Reservation push endpoint** - see [Mews: Process group](/channel-manager-api/mews-operations/reservations.md#process-group) * **Client Token** - will be provided to you by Mews following certification in the demo environment (e.g. `C66EF7B239D24632943D115EDE9CB810-JJ549OU4JF94692C940F6B5A8F9453D`) * **Connection Token** - will be provided to you by Mews or by the property on request, or via [Mews: Get properties](/channel-manager-api/mews-operations/configuration.md#get-properties) (e.g. `NF9R27B239D24632943D115EDE9CFH3-EA00F8FD8294692C940F6B5A8F9453D`) ## Channel Manager side environments Similar to the Mews side, there should be two environments with different `clientTokens`. The test Demo environment will be used by Mews to verify the connection before transitioning to the live Production environment. ## Allowlisting Allowlisting (formerly called '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. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

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/channel-manager-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.
