Activate when:

• User requests to create an API
• User wants JSON endpoints
• User mentions: API, REST, JSON, endpoint, web service

API Controller Template

component extends="Controller" {

    function config() {
        provides("json");
        verifies(only="show,update,delete", params="key", paramsTypes="integer");
        filters(through="requireApiAuth");
    }

    function index() {
        resources = model("Resource").findAll(order="createdAt DESC");

        renderWith(
            data=resources,
            format="json",
            status=200

    }

            renderWith(data={errors=resource.allErrors()}, format="json", status=422);
        }
    }

    function delete() {

        renderWith(data={message="Deleted"}, format="json", status=204);
    }

    private function requireApiAuth() {
        var headers = getHTTPRequestData().headers;

        if (!structKeyExists(headers, "Authorization")) {
            renderWith(data={error="Unauthorized"}, format="json", status=401);
            abort;
        }

        // Validate API token
        var token = replace(headers.Authorization, "Bearer ", "");

            renderWith(data={error="Invalid token"}, format="json", status=401);
            abort;
        }
    }

    private boolean function isValidApiToken(required string token) {
        // Token validation logic
        return true;
