hi,
I have 3rd party payment service, when my customer purchase order in 3rd party payment service successful then 3rd party payment service must call api to update order record in my portal app
I have research and found Portals Web API
https://docs.microsoft.com/en-us/powerapps/maker/portals/web-api-overview
But it seem to be used only inside Power Apps portals pages
Could you suggest me the best approach for this please?
Thanks
