Create credentials for an SDK app
An SDK app has a built-in PKCE flow for the default login. To use a custom login for the app, you need to set a PKCE flow for the custom login after you get app credentials. See set up authorisation code grant with PKCE for more information.
- An account for the Developer Portal. If you don't have this, sign up for a developer account.
- A bundle ID (iOS app identifier) or app package (Android app identifier).
- A working and publicly available URL. It includes a redirect URI to direct your app users back to your app, after they authorise it to access their Zettle merchant data. For example,
awesomeapp://zettlelogin. You will use it to get SDK credentials for a new app.If the URL is located at your local server, you can make the URL publicly available using ngrok.
Follow these steps to get new app credentials.
- Log in to the Developer Portal.
- On your Dashboard, click Create app credentials.
- On the Create app credentials page, click Payments SDK for iOS or Payments SDK for Android to open the form with app information.
- Fill in the form. For the OAuth Redirect URI field, fill it in with the URL that you have prepared.
- Click Create credentials to create the app credentials.
- Save the app credentials somewhere safe.
- To use custom login for the SDK app, see set up authorisation code grant with PKCE.
