I have this return um FacebookResponseException
{"error":{"message":"(#200) Permissions error","type":"OAuthException","code":200,"fbtrace_id":"A5M1AUs-EmXpmelhakEuK3c"}}

Hi ,
We are trying to incorporate a feature into our web application in which we want to send a request to a page for granting the access. So, could you help us finding an API that we can integrate and have our system send request to a Facebook page for their access via our own app.
Kindly, guide us with this.
Thanks!

When generating the Token and running, we received the following error:
Forms 400 {"error":{"message":"Any of the pages_read_engagement, pages_manage_metadata,\n pages_read_user_content, pages_manage_ads, pages_show_list or\n pages_messaging permission(s) must be granted before impersonating a\n user's page.","type":"OAuthException","code":190,"fbtrace_id":"A-MxMGyeKy_vgi4P6Tsi8B8"}}
However, all permissions requested in the error were already selected when generating the Token. The part "permissions must be granted must be granted before impersonating the user page" doesn't tell me what should be done.

I'm looking to help the engineering team implement Conversions API for two regions and the ecommerce platform is powered by Hybris SAP. Any guides or quickstarts?

I'm developing an application for Whatsapp Business which uses Cloud API. Everytime i generate an 'Access Token', the number that should send message to test the application can't be used because of the error in the pic.
