Support
Email us or use the form below. We're a small team and we usually reply within one business day.
You're in the right place. Use the form below, or email support@zaptrain.com. If you're signed in we'll see which account you are, so there's no need to describe it.
Contact the business — their email address is on the payment page and in their emails. They set the amount and the terms, and we can't change or refund a payment on their behalf.
Subscribed? Manage it, switch how you pay or cancel from the link in your emails. If you pay automatically, you can also delete the connection in your wallet app at any time; that stops all payments.
Tell us. Anyone can sign up and send invoices through Zaptrain, so if one looks like an impersonation or a scam, don't pay it — send us the payment link and we'll investigate the account behind it.
Pick “Reporting a suspicious invoice” in the form, or email support@zaptrain.com.
Common questions
Install Lexe, then in Settings → Wallet choose Connect with Lexe and scan the code with the Lexe app. (You can also paste a client credential with the Receiver role.) Zaptrain checks the connection with Lexe and refuses anything that could spend from your wallet.
In your Lexe wallet already. Zaptrain never holds your funds: payments settle straight from your customer to you, so “Paid” on the dashboard means the sats have landed. Open the Lexe app to see the balance.
No. Lightning payments are final, and because we never hold the money we have no way to pull one back. To refund a customer, send them the amount from your Lexe wallet yourself.
Create a plan on Subscriptions and share its link, or email it with Send to customer. Customers either connect a wallet once (Nostr Wallet Connect) and are charged automatically within a budget they set, or pay each renewal from an emailed link. Every payment lands in your Lexe wallet as a normal invoice.
One percent of each invoice that gets paid, and nothing else — no monthly fee, no charge for unpaid invoices. Lexe's receive fee comes out of that 1%, so it is not added on top.
Ask us below or email support@zaptrain.com and we'll handle it. The Privacy Policy sets out what we hold and for how long.
Building on the API? The API docs and the MCP setup guide cover most of it.
