Use

use Jalismrs\Symfony\Bundle\JalismrsApiThrottlerBundle\ApiThrottler;

class SomeApiClass {
    private ApiThrottler $apiThrottler;

    public function __construct(
        ApiThrottler $apiThrottler
    ) {
        $this->apiThrottler = $apiThrottler;
        
        /*
         * register rate limits HERE
         * https://packagist.org/packages/maba/gentle-force
         */
         $this->apiThrottler->registerRateLimits(
            'useCaseKey', // string $useCaseKey
            [],           // array  $rateLimits
         );
    }
    
    public function someApiCall(): void {
        $this->apiThrottler->waitAndIncrease(
            'useCaseKey', // string   $useCaseKey
            'identifier', // string   $identifier
            4,            // int|null $cap
        );
        
        // api call HERE
    }
}

Configuration

Try limits can be configured:

• for all calls
• for all 'useCaseKey' calls
• for all 'useCaseKey.identifier' calls
• for a specific call with $cap parameter

# config/packages/jalismrs_api_throttler.yaml

jalismrs_api_throttler:
    cap: 1
    caps:
        useCaseKey: 2
        useCaseKey.identifier: 0
    redis:
        parameters:
            host: 'redis_host'
        options:
            prefix: 'redis_prefix'
