This is your developer portal where you can manage your integrations
Now let’s focus on creating your first app! (hopefully out of many)
Click on the button ‘skapa app’ and see what’s happening!
Now for the tricky part, choose a name for your app, take your time!
Great, now you have to choose your scopes, scopes what is that?? ( you need to choose what part of our program you want your app to connect to, for example if you want to send data to our payroll software you choose ‘Lön’ as a scope, so figure out what scopes you need and check those boxes)
Last but not least press ‘Save’
You did it, congrats on your first app!
Now you can specify descriptive information about your app and keep track of your Client-Id and Client-Secret.
The Fortnox developer portal is where you create and manage your apps. When published, users can connect their Fortnox account to your system.
You can also create test accounts (step 3), see statistics and apply to get your app in our app market.
The developer portal is our platform for you as a developer against our API and app market, this is where we provide news to you and add new functionality etc.
Create your test database
Now it’s time to do your first action as a developer, create your first own test database. Try out your code in a safe environment before connecting your live customers by creating test databases.

Time to explore Fortnox functionality!
Connect your integration
Take your integration out for a spin by connecting it to your shiny new test environment. This is the place to iron out any kinks.
The authorization of access to a customer’s account is made using the OAuth2 Authorization Code Flow. In essence, this means that a user grants your integration access to their account. The user must approve the access and scope of access to their account during the activation process.
For more information about the Access-Token request, please refer to Get Access-Token.
The Authorization-Code is valid for 10 minutes before becoming invalid and can only be used once to retrieve the Access-Token.
The Access-Token is retrieved by sending a POST request to the /oauth-v1/token endpoint.
