How can I get prayer times calculation method for specific country
malekkhasawneh Alaykum Salaam. The methods pre built into the API are listed on https://aladhan.com/calculation-methods or in the API documentation with each endpoint. The page also contains instructions on how to use the API to compute the timings for a 'custom' method, i.e., one not included in the API.
@malekkhasawneh @zihadrizkyef If you do not specify a method, the API will calculate the closest authority from the ones listed on https://aladhan.com/calculation-methods and compute the times based on that. If you know the authority that defines the angles for your country (https://kemenag-jakpus.id/ being the case for Indonesia), you can either use the method id 99 as explained on https://aladhan.com/calculation-methods with the custom angles, or just get the angles from the authority and raise a PR on https://github.com/islamic-network/prayer-times/blob/master/src/PrayerTimes/Method.php, and the API will then support that method.
I hope this helps, insha Allah!
