Review a wallet's token balances after a failed payment
A failed payment creates another follow-up. Add a quick on-chain balance check to the review so the next step has more context.
Trigger
Payment Intent Failed Trigger
Triggered when a payment intent fails in Stripe
Action
Get Token Balances
This tool retrieves erc20 token balances for a specified ethereum address. it can either return balances for all tokens an address has ever interacted with or for a specific set of token contract addresses. it is useful for checking token balances for wallets, monitoring erc20 token holdings, portfolio tracking, and defi applications.
Why this helps
After a payment fails, founders may need to investigate whether an on-chain payment option is practical, but switching tools to look up a wallet adds friction.
- Adds wallet balance context to a failed payment review
- Reduces manual lookups across Stripe and blockchain tools
- Keeps the payment issue and its follow-up together
Setup
Build it in a few focused steps.
- 1Connect Stripe and Alchemy once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, ask Notis to retrieve ERC-20 balances for the relevant wallet after a payment intent fails and include the results in the run report.
- 4Pick the Stripe Payment Intent Failed trigger and choose where run reports should go.
- 5Test with one real failed payment example and a wallet address available to the automation.
Questions about this workflow
Does a failed Stripe payment provide the customer's wallet address?
Not necessarily. Make the wallet address available to Notis in the event context or another supplied source before relying on the lookup.
Can this retry or collect the payment on-chain?
No. The available Alchemy action retrieves token balances only. It does not initiate a payment or retry the Stripe charge.
What will the Alchemy action return?
It retrieves ERC-20 token balances for a specified Ethereum address, for all interacted tokens or specified token contracts.
