Hi, I'm working to get the refresh token using OAuth. I have the code below, and it gives me the error: Error: 400, {"error":"invalid_grant","error_description":"the provided authorization grant code is invalid or was issued to another client"}. Any ideas??
import requests
import base64
client_id = sandbox_client_id
client_secret = sandbox_client_secret
redirect_uri = sandbox_redirect_uri
code = code
url = 'https://api.sandbox.ebay.com/identity/v1/oauth2/token'
auth = base64.b64encode(f'{client_id}:{client_secret}'.encode()).decode()
# Request headers
headers = {
'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': f'Basic {auth}'
}
# Request body
data = {
'grant_type': 'authorization_code',
'code': code,
'redirect_uri': redirect_uri
}
response = requests.post(url=url, headers=headers, data=data)
