Sandbox OAuth + app_fee_money: where should the application fee appear?

Hi Square Developer Community,

I am testing a marketplace-style payment flow in the Square Sandbox.

The intended flow is:

  • The application is the Square developer application/platform.

  • A creator connects their Square account through OAuth.

  • A fan makes a $5.00 payment to the creator through the application.

  • The application sets app_fee_money to 20% ($1.00).

  • The creator should receive the remaining amount after the Square processing fee and the $1.00 application fee.

  • The $1.00 application fee should go to the developer/platform account.

The payment was successfully completed in Sandbox.

The Square transaction shows:

  • Gross payment: $5.00

  • Square processing fee: $0.45

  • Application fee: $1.00

  • Amount transferred: $3.55

  • Fee source shows: Square $0.45 and Default Test Account $1.00

The payment was created using the creator’s OAuth access token, and the request includes:

app_fee_money = $1.00

My confusion is about the Sandbox accounts.

In the Square Developer Dashboard I currently see several Sandbox accounts, including:

  • Default Test Account

  • FS Payments

  • FS Creator Test

The successful payment shows Default Test Account as the location where the payment was collected.

However, when I check the FS Payments Sandbox account, I do not see the $1.00 application fee in its balance.

My questions are:

  1. Which Sandbox account should receive the app_fee_money in this setup?

  2. How can I identify the actual developer account associated with the Square application?

  3. Where should the $1.00 application fee appear in the Sandbox Dashboard?

  4. Does the fact that the transaction shows “Default Test Account $1.00” mean that Default Test Account is receiving the application fee, or is that simply how the fee is displayed on the seller side?

  5. Is a separate Sandbox seller account such as “FS Creator Test” required for properly testing the OAuth + application-fee flow?

I want to verify the complete money flow in Sandbox before switching the application back to Production.

Thank you.

App fees are not fully supported in sandbox so you can’t see the end to end flow without moving to production. App fees go the main location in the developer account.
