Trolley (formerly Payment Rails) is a payout platform built for international creators. It handles compliance, tax forms, and transfers across many countries.

​
What it does

  • Sends payouts to bank accounts, PayPal, and other local methods
  • Collects tax forms (W-9, W-8BEN) automatically
  • Handles currency conversion and compliance reporting

​
Before you start

  • A Trolley account with a funded balance
  • API credentials from your Trolley dashboard

​
Connect

1

Create API credentials

In Trolley, open Settings → API keys and create a new access key and secret.
2

Open the integration

In Afflo, go to Integrations → Payments → Trolley and click Connect.
3

Enter credentials

Paste the access key and secret, confirm the environment (live vs. sandbox), and save.
4

Verify

Afflo validates the credentials and shows the integration as Connected.

​
How payouts work

  1. You click Pay All on the Payouts page.
  2. Afflo sends the payout instructions to Trolley.
  3. Trolley uses the payout method the partner set up in their Trolley onboarding (bank, PayPal, etc.).
  4. Once a partner completes tax forms and verification, payouts flow automatically.
Partners sign up for Trolley with a secure link the first time. They’ll see the link in the email Trolley sends them.

​
Disconnect

Open Integrations → Payments → Trolley and click Disconnect.

​
Tips

  • Use Trolley when you work with partners outside your country — the compliance handling saves hours per cycle.
  • Encourage partners to complete their Trolley onboarding and tax forms early, before the first payout runs.
  • Keep funds topped up in Trolley; a low balance pauses all in-progress transfers.

​
Troubleshooting

“Authentication failed.” Double-check you copied the access key and secret completely, and that the environment matches (live credentials won’t work in sandbox). Payout stuck in Processing. Trolley often waits on partner tax/verification. The partner sees a message in their Trolley account with what’s outstanding. Partner wants to change method. They change it in Trolley (not Afflo). The next payout uses the new method.
