If you have not yet set up the order integration, we recommend doing so first. See [Connecting to 3S POS — Orders](https://support.slerp.com/knowledge/connecting-to-3s-pos-?hsLang=en) for more details. Note that if the order integration and product mapping are not set up, the integration will not be able to support points-based loyalty on a per-product basis, or rewards that are limited to specific products. --- ### Overview To connect Slerp to 3S POS Loyalty you need to do the following: 1. **In Controls**, ensure all stores and inventory are set up. 2. **Contact 3S POS** to obtain a Location ID for each store you want to connect. 3. **Contact Slerp** and pass over your Location IDs so that we can finalise the setup. 4. **Place a test order** to verify that points and rewards are working correctly. --- ### Prepare your stores in Controls Before setting up the loyalty integration, make sure the following are in place in Controls: - All store locations have been created - Inventory setup is complete for each location, including menus, products, and modifiers --- ### Request Location IDs from 3S POS ✏️ Note that 3S POS uses two different store identifiers. A **Location ID** is used for the loyalty integration. A **Slerp Location Channel ID** is used for the order integration. Make sure you are requesting the correct one. Contact 3S POS to request a Location ID for each store you want to connect. Send an email to [support@3s-pos.com](mailto:support@3s-pos.com). For each store, include: - The Slerp store name - The store address Here is an example email you can use: **To:** [support@3s-pos.com](mailto:support@3s-pos.com) **Subject:** Slerp Loyalty - Location ID Request --- Hi 3S POS Support, I would like to set up the Slerp loyalty integration for my business. Business name: **\[Your 3S POS Business Name\]** Please could you provide a Location ID for each of the following stores: 1. **\[Slerp Store Name\] — \[Store Address\]** 2. ... Thank you, **\[Your Name\]** --- ### Pass your Location IDs to Slerp Once you have received your Location IDs from 3S POS, pass them to Slerp so that we can complete the setup. Slerp will then work to provide you with a URL, client id and client secret so that we can communicate with the POS securely. --- ### Configure the integration in 3S POS Once Slerp has provided your credentials, you will need to enter the following into your 3S POS settings: - **URL:** provided by Slerp - **Menu Sync System UID:** provided by Slerp - **Client ID and Client Secret:** provided by Slerp **Step 1.** Set up the integration in 3S POS.
