# Mobile SDK - Resolver setup Source: https://dev.arcxp.com/mobile/content/mobile-sdk-resolver-setup/ This set up sets up the backend for the Mobile SDK. Resolvers populate the content to outbound feeds (OBF). Without resolvers, no data is available. Use caution when editing or adding resolvers as small mistakes can cause data to not be available. The resolvers provided in this document are the resolvers that power collections, navigation, article, and site service calls to the mobile SDK. Setting up these resolvers lets content feed into the endpoints that the Mobile SDK uses. To learn more, see [Setting up resolvers for Outbound Feeds](https://dev.arcxp.com/arc-io/developer-docs/setting-up-resolvers-for-outbound-feeds/). ## Confirming the resolver functionality is enabled Use the following steps to confirm the resolver functionality is enabled in your environment. A different resolver set exists for each environment, so ensure you select the appropriate environment before navigating. 1. Navigate your organization’s Arc XP home page. 2. Click the **outbound feeds** tile under Experiences. PageBuilder opens. > **Note:** > > If you don’t have an outbound feeds under Experiences, contact [Arc XP Customer Support](https://support.arcpublishing.com/) to have the Outbound Feeds product added. 3. Click **Developer Tools > Resolvers** from the menu at the top. 4. Click **New Resolver**. 5. Scroll to the Default Template section and expand the drop-down menu. Confirm an `ans` entry exists. If the entry does not exist, contact [Arc XP Customer Support](https://support.arcpublishing.com/) and request that the OBF bundle be installed that includes an Arc XP Native Specification (ANS) template. If the template is not installed, discontinue this tutorial until the OBF bundle is installed and the template is available. ## Default Resolver Parameters The following list describes the resolvers that you must set up in order to feed content to the outbound feeds that the Mobile SDK uses. > **Note:** > > If any of the content sources described here are not available in your drop-down menu, see [Deploying new outbound feeds features](https://dev.arcxp.com/arc-io/developer-docs/deploying-new-outbound-feeds-features/) to create or update your OBF repository bundle and re-deploy. Testing Notes: - OBF only returns published items - UUIDs are case sensitive | NavigationFeeds the site service data.
