Use this guide to create an app in the COSMIC developer portal, configure its redirect URIs, and save its credentials.

​
Before you begin

​
Create your app in the portal

1

Open the developer portal

Go to natecosmic.com/developers and sign in.
2

Create a new app

Select the option to create an app, then enter your app name.
3

Choose a client type

Select whether your app is a public client or a confidential client.Use a public client if your app runs in an environment that cannot securely store a client secret, such as a single-page app, mobile app, or desktop app.Use a confidential client if your app has a trusted backend that will securely store a client secret.
4

Add redirect URI values

Add the redirect URI(s) your app will use.
5

Select scopes

In the app settings, enable each scope your integration needs. Users see the same list at consent before they approve your app.See Scopes for what each scope allows and how to choose them.
6

Save and capture credentials

After creating the app, copy and securely store your client_id.If your app is a confidential client, also copy and securely store your client_secret.
Treat client_secret like a password. Store it in a secure secret manager and never commit it to source control.Public clients do not receive a client_secret.
