Everyone here is a volunteer, so suggesting that they respond in any stated time frame isn't likely to help (to the contrary, it'll likely hinder).

Your question also lacks clarity. We have no idea what you're specifically trying to accomplish, what you've tried, or what specific problems you're actually having.

In general, folks are here to help others with issues they've encountered while trying to accomplish a task. In your case, it sounds like you'd be best served by doing a Google search for "how to consume an api in laravel".

Well thank you for responding. For clarity I have build an cricket app which requires tournament brackets, matches and Its scheduling. Mentioned API can fulfill my requirements. API contains resources. But I am new to API integration or consuming in laravel. Or how to handle API stuff? This API is suitable for my requirements or not? kindly suggest too. Thanks

Response Formats: XML or JSON.
