List EventBridge targets for a rule using an Amazon SDK

The following code examples show how to list Amazon EventBridge targets for a rule.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

List all of the targets for a rule using the rule name.

/// <summary> /// List all of the targets matching a rule by name. /// </summary> /// <param name="ruleName">The name of the rule.</param> /// <returns>The list of targets.</returns> public async Task<List<Target>> ListAllTargetsOnRule(string ruleName) { var results = new List<Target>(); var request = new ListTargetsByRuleRequest() { Rule = ruleName }; ListTargetsByRuleResponse response; do { response = await _amazonEventBridge.ListTargetsByRuleAsync(request); results.AddRange(response.Targets); request.NextToken = response.NextToken; } while (response.NextToken is not null); return results; }
