Copy the redirect URI
In the Authdog console, select the project and environment, open Authentication > Providers, find PayPal Sandbox, and click Enable. Copy the redirect URI shown in the form:
https://identity.authdog.com/api/v1/callback/<connectionId>Create the application
- Create the app under Sandbox in the PayPal Developer Dashboard.
- Enable Log in with PayPal and add the redirect URI from Authdog as a Return URL.
- Create sandbox personal accounts under Testing Tools > Sandbox Accounts.
- Copy the sandbox app's Client ID and Secret.
Configure Authdog
| Field | Value |
|---|---|
| Client ID | The client identifier from the provider |
| Client Secret | The client secret from the provider |
Save, then toggle the connection active.
What PayPal Sandbox returns
Authdog requests the openid profile address scopes and reads the profile from https://api.sandbox.paypal.com/v1/identity/oauth2/userinfo.
Sandbox responses mirror live ones. Sandbox buyer accounts have their own credentials, real PayPal logins will not work here.
Configure this connector in a development environment and the live connector in production so a test credential can never issue a production session.
Test it
- Open your environment's hosted sign-in page, or link to
https://identity.authdog.com/api/v1/signin/<connectionId>. - Select the PayPal Sandbox button and complete the flow.
- Confirm the user appears under Users in the console with a PayPal Sandbox identity linked.
Troubleshooting
| Symptom | Cause |
|---|---|
invalid_client |
Live credentials used against the sandbox endpoint, or the reverse |
| Redirect or callback URL error | The URI registered with the provider does not match Authdog's exactly |
| Works in one environment only | Each environment has its own connectionId, and so its own redirect URI to register |
