Zoho API Deal Creation and Pipeline

I want to sync my zoho crm and backend with eachtoher, I can receive webhooks from crm and sync from it but when I try to sync to crm , I get this error for Deals module Zoho error: {

data: [

{

code: 'MANDATORY_NOT_FOUND',

details: [Object],

message: 'required field not found',

status: 'error'

}

]

}
Details contains a message saying Pipeline field is missing ,

I could not fetch my pipelines with the endpoint

https://www.zohoapis.eu/crm/v3/settings/pipeline,

it raises an error saying oauth scope

data: {

code: 'OAUTH_SCOPE_MISMATCH',

details: {},

message: 'invalid oauth scope to access this URL',

status: 'error'

}
How can I enable my access tokens to access Pipelines ?
