Sending Text Message throwing error

[ebadhassanDev]

Unsupported post request. Object with ID 'messages' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api

I got this error while sending the nromal text message, I've attached all the IDs in program.cs file
How can I do Now I just clone your project.

Thanks

hi, a post request for sending the message does not contain messages, this is what a post request looks like;

curl -i -X POST `
  https://graph.facebook.com/v17.0/{phone number id}/messages `
  -H 'Authorization: Bearer {your token}' `
  -H 'Content-Type: application/json' `
  -d '{ \"messaging_product\": \"whatsapp\", \"to\": \"{your phone number/test number}\", \"type\": \"template\", \"template\": { \"name\": \"hello_world\", \"language\": { \"code\": \"en_US\" } } }'
