Monzo Webhook

Serde-compatible structs containing the data from a Monzo bank webhook.

For examples of what different webhooks look like, see src/tests.txt.

Usage

When implemented a receiver for a Monzo bank webhook, you can use these structs. For example, with axum:

async fn test_webhook_parse(Json(data): Json<monzo_webhook::Webhook>) -> String {
    format!("{data:#?}")
}

Testing

This has been tested against the following types of transactions:

• Faster Payments in- and outbound
• Monzo-to-Monzo transactions
• Pot and Account Deposits and Withdrawals
• Contactless purchases
• Online purchases

This needs confirmation that it works with:

• ATM withdrawals
• ATM deposits
• Deposits
• Cheques
• Online refunds
• Chip & PIN purchases
• Chip & PIN refunds
• Contactless refunds
• Direct Debits
• Standing Orders
• BACS Credits
• BACS Debits
• CHAPS Transfers
• International Transfers via Swift
• Fees and Charges
• Interest Paid
• Interest Earned

If you have any JSON webhook payloads of these types of transactions, I would appreciate seeing them. You are recommended to scrub any sensitive data or ID numbers first, then please open an issue.
