How to connect to Procountor

To get started with Procountor integration, you first need to set up a sandbox environment for testing. Once testing is complete, you can proceed to the production environment.

​
Setting up the Sandbox Environment

1

Request a Procountor Test Environment

You must request your own test environment from Procountor. Navigate to the Procountor test environment request form and fill it out with the following information:
  1. Company Information: Provide details about your company
  2. Purpose: Select “Integration platform”
  3. Type of Integration: Choose “Common API Client = Integration will be publicly available to be used by any company”
  4. Redirect URI: Set to https://api.maesn.dev/auth/callback/procountor-sandbox
  5. Transferred Data: Include invoices, chart of accounts, VATs, ledger receipts, persons, currencies, bank accounts, payments, etc.
  6. Direction: Select “Both” (read and write)
  7. Countries: Select “Finland and Sweden”
  8. Policies: Accept all required policies

Wait for Client Credentials

After submitting the request, Procountor will review the application and provide the client credentials (Client ID and Client Secret).
  • This process typically takes 3-4 days
  • The credentials will be sent to your email and your phone number as a text message
  • Procountor will also send test account credentials that can be used as a test user for the integration using the sandbox
  • The test account can be accessed in the browser (UI) via https://pts-secure.procountor.com/procountor/
  • Login process: The first login only requires a username and a personal password. After the first login, you can choose from two secure methods for verifying subsequent logins:
    • One-time passwords: The third step in the login process will be entering a four-letter password from the password list. Before logging in, make sure your browser allows pop-up windows so you can open the password list.
    • Finago Procountor Key mobile app: Verify your login using the mobile application.
  • You may change the verification method at any point after the first login.
  • Note: On the test server, automatic forgotten password resetting and sending options are not available.
  • Once received, securely store these credentials

Submit Credentials to Maesn

Finally, once you receive your credentials from Procountor, set up your API tenant with your application’s details:
  • Contact your maesn representative to submit the client ID and client secret.
If you are not sure who your technical contact is, do not hesitate to reach out to us.

Test Your Integration

With the sandbox environment configured, you can now:
  • Test all integration features in a safe environment
  • Verify data synchronization and workflows
  • Debug any issues before going to production

​
Moving to Production

Once testing is complete in the sandbox environment, follow a similar process to set up the production environment:
  1. Navigate to the Procountor production access request form and fill it out with the same information as the test environment request, but with the following changes:
    • Redirect URI: Set to https://api.maesn.dev/auth/callback/procountor (without -sandbox)
    • Authentication: Select “API authentication” option
    • All other fields remain the same (company information, purpose, type of integration, transferred data, direction, countries, and policies)
  2. Wait 3-4 days for Procountor to send the production credentials via email
  3. Create a production test account:
  4. Submit the production credentials to Maesn to configure the procountor target system
  5. You can now use Procountor in production
