Slim SDK

APItoolkit is an end-to-end API and web services management toolkit for engineers and customer support teams. To integrate your Slim (PHP) application with APItoolkit, you need to use this SDK to monitor incoming traffic, aggregate the requests, and then deliver them to the APItoolkit's servers.

Installation

Kindly run the command below to install the apitoolkit-slim sdk and otel packages:

composer require \
    open-telemetry/sdk \
    open-telemetry/exporter-otlp \
    open-telemetry/opentelemetry-auto-slim \
    open-telemetry/opentelemetry-auto-psr18 \
    apitoolkit/apitoolkit-slim

Setup Opentelemetry

Installing opentelemetry extension

After installing the necessary packages, you'll need to install the opentelemetry extention and add it to your php.ini file

pecl install opentelemetry

Then add it to your php.ini file like so.

[opentelemetry]
extension=opentelemetry.so

Export the following environment variables to configure the opentelemetry extension.

export OTEL_PHP_AUTOLOAD_ENABLED=true
export OTEL_SERVICE_NAME=your-service-name
export OTEL_TRACES_EXPORTER=otlp
export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
export OTEL_EXPORTER_OTLP_ENDPOINT=http://otelcol.apitoolkit.io:4318
export OTEL_RESOURCE_ATTRIBUTES="at-project-key={ENTER_YOUR_API_KEY_HERE}"
export OTEL_PROPAGATORS=baggage,tracecontext

Setup APItoolkit Middleware

Next, create a new instance of the APIToolkitMiddleware class and register the middleware with the Slim Framework in the app/middleware.php file. This creates a customs spans which captures and sends http request info such as headers, requests and repsonse bodies, matched route etc. for each request

use Slim\Factory\AppFactory;
use APIToolkit\APIToolkitMiddleware;

require __DIR__ . '/vendor/autoload.php';

$app = AppFactory::create();

$apitoolkitMiddleware = new APIToolkitMiddleware(['captureRequestBody' => true]);

$app->add($apitoolkitMiddleware);

$app->get('/', function ($request, $response) {
    $response->getBody()->write('Hello, World!');
    return $response;
});

$app->run();

Note

The {ENTER_YOUR_API_KEY_HERE} demo string should be replaced with the API key generated from the APItoolkit dashboard.

Important
