Public/Private keys for Google developers service account -

i've been going on while , can't manage understand how obtain public/private keys automatically created service account in google developers console.

i making python script imports data using gspread google spreadsheet, , authenticate myself through signedjwtassertioncredentials need existent service account

the issue is:

i create new project using: "create project"

but when go permissions/permissions, see the service account need created, don't have keys it.

i want know how @developer.gserviceaccount.com keys since have tried importing data google spreadsheets using other @xxx-22324.iam.gserviceaccount.com no luck, says email address not exist.

edit:

whenever go api manager / credentials possibility generate key @mxxx-22324.iam.gserviceaccount.com (the 1 can't use)

i solved issue:

google has updated service account detail format , it's way of sharing spreadsheets service accounts can accessible gspread.

i created service account new formating : xxx@montredo-22324.iam.gserviceaccount.com , set exact same file google generates json read application:

login = signedjwtassertioncredentials(json_key['client_email'], json_key['private_key'], scope) 

then shared without notifications spreadsheet service account email (the same in json file mentioned)

and voila.
