Attachment Rest API to Uploads a specified binary file as an attachment to a change request table

[mshetty794]

I am trying to post a binary file as an attachment to a change request table using user who has itil role permission, On Post Api call from postman I am getting below error 

https://<instance >/api/now/attachment/file?table_name=change&table_sys_id=eb54c83a2f526010f48ed3f62799b638&file_name=test

Post API

Response

{

"error": {

"detail": "User is unauthorized to write to table: change",

"message": "User not authorized"

},

"status": "failure"

}

Can you help me what additional role need to be assigned. Currently user is assigned with itil role.

@mshetty794 

ensure that user has table level WRITE ACCESS to change_request table

Then only the attachment can be added

also noted the table name is incorrect
