Create a Fortnox integration

1. Register for Fortnox developer access.

2. In Fortnox, open Menu → Developer Portal.

3. Create an integration and select only the scopes your product requires.

4. Record the Client ID and Client Secret securely.

5. Create a sandbox in the developer portal and complete the invitation sent by Fortnox.

Fortnox documents its available permissions in Scopes.

Configure Zwapgrid

1. In the Client Portal, open Systems → Fortnox → Configure.

2. Create a System Setting with a descriptive name.

3. Copy the redirect URI displayed by Zwapgrid to the Fortnox integration.

4. Select the scopes required by your API.1 and Proxy.1 operations.

5. Make sure the Zwapgrid scopes match the scopes registered in Fortnox.

6. Enter the Fortnox Client ID and Client Secret when using your own application.

7. Save, review, and publish the setting.

See System Settings for lifecycle and Consent-selection rules.

Test and move to production

1. Add representative accounting data to the Fortnox sandbox.

2. Create a Development Consent using the published setting.

3. Complete the Onboarding Flow.

4. Test every required operation, including write operations where applicable.

5. Follow Fortnox's publication or private-integration process before onboarding production customers.

Adding scopes to an existing Fortnox application does not automatically grant them to previously activated customers. Those customers may need to reactivate the integration.
