Discover Api
In discover Api's: /discover/movie,

1. which parameter I can use for the service filter? You are using with_ott_providers for the service filter so Can I use the same for this? I didn't see this key in this API.
   
2. where we can find a service ID?
   
3. what is the meaning of with_watch_providers? where do I find the provider ID?
   

I'm not sure I understand you correctly, but...

Thank you for your response.

Again I tried to explain my problem,

On TMDB, I go to the Popular Movie option then I used some filters like released from date =2021-08-01, released to date = 2021-09-01, provider= netflix, region= US. I got some results which are ok. when I check API on the network tab, I can see you used 'with_ott_providers' for providers so I also try your API through Postman.

This is the API which I tested on postman:

https://api.themoviedb.org/3/discover/movie?api_key=*********&language=en-US&sort_by=popularity.desc&air_date.lte=2022-01-23&ott_region=US&page=1&release_date.gte=2021-08-01&release_date.lte=2021-09-01&with_ott_providers=8

I got the same result from this API also.

But you do not mention the 'with_ott_providers' key option in the discover/movie-discover API documentation.

After your reply I tried this option also: https://api.themoviedb.org/3/discover/movie?api_key=*******&language=en-US&sort_by=popularity.desc&page=1&release_date.gte=2021-08-01&release_date.lte=2021-09-01&with_watch_providers=8&watch_region=ISO 3166-1

still, I have not received the same result which I see on the website with filters.

Can you please tell me what am I doing wrong?

I think only Travis Bell, the administrator, can answer your question.
Let's wait for him to come by.

EDIT
I tested the two Requests you posted.
The result was the same for both.
What I changed in the one that didn't work for you was from ISO 3166-1 to US
