client_secret are unique credentials provided to any partner beginning an integration with Deliverect. These can be used to access all customer accounts which we've connected to your partner account.
If you have already been provided a partner account and credentials, you can obtain an OAuth token with our Machine to Machine token endpoint and begin making calls with our API.
Don't forget to cache this token. You should only request a new one when your current one has expired.
You can use this tool to see the contents of the token.
Only certified integrations will be provided partner credentials for our production environment.
Never share your partner credentials with anyone else
Please be aware that we provide one clientId and one clientSecret which allows access to all connected customer accounts and these credentials don't change per integrated account.
