You may wish to track user behaviour in contexts that Snag is unable to obtain a data source for (e.g. in a non-web/blockchain based game). For this and similar cases, Snag provides the concept of external rules. An external rule is mostly the same as a standard loyalty rule and differs only in that it contains no built-in execution and evaluation logic. Instead, this is done application-side (e.g. in-game) and, when a rewardable action is identified, Snag's [`POST /api/loyalty/rules/{id}/complete`](https://docs.snagsolutions.io/api-reference/loyalty/complete-loyalty-rule) endpoint can be hit. This tells Snag that a given rule was completed by the given user(s) and issues the associated reward. You can get more details on how to complete a rule in the [Submit and verify loyalty rule completion](/loyalty/verifying-rule-completion) recipe. The id returned in the response will be used to complete the rule when a user performs the required action. ## Evaluating external rules Unlike built-in rules, the evaluation of external rules happens within your own system. This means you must track the user behavior (e.g., game milestones or external API interactions) and determine when a rule is completed. Once a rewardable action is identified, you can programmatically notify Snag by completing the external rule using the API (see next step). ## How to issue points for users who complete an external rule To issue points for a user who completes an external rule, use the [`POST /api/loyalty/rules/{id}/complete`](https://docs.snagsolutions.io/api-reference/loyalty/complete-loyalty-rule) endpoint. This endpoint informs Snag that the rule has been satisfied for a specific user and triggers the reward. You can get more details on how to complete a rule in the [Submit and verify loyalty rule completion](/loyalty/verifying-rule-completion) recipe. Once the request is processed, Snag will issue the reward to the user based on the rule’s configuration. ## Summary Workflow 1. Create the External Rule: Use our admin dashboard to create the rule. 2. Track Behavior: Use your application to monitor user actions that meet the rule’s criteria. 3. Complete the Rule: When a user completes the action, submit the rule completion to Snag using the API, more details can be found in the [Submit and verify loyalty rule completion](/loyalty/verifying-rule-completion) recipe.
