How to filter Power BI by POST in Embedded Dashboard

Hello everyone,

I have embedded a Power BI Dashboard into my PHP app. For some reason I had to do filtering by URL, so I use:

&filter=Categories/Category in ('1', '2', '3')'

Now I have an array with more than a thousand values so it is not possible anymore to do it by URL.

Can you please help me if there is some other way to do filtering, by POST for example and ajax or JavaScript?

Thanks in advance!
