Can Revatto re-attempt a failed NMI charge automatically?

No. Revatto's recovery on NMI is managed multi-channel outreach (AI-timed email + SMS + a human specialist) that drives the customer to update their card — not a silent re-charge through the gateway.

Does NMI recover failed payments on its own?

Not by itself. NMI is a gateway — it returns a decline response code when a charge fails. Any retry schedule or customer notification is configured in the recurring-billing or merchant integration on top of it, and NMI provides no SMS or human outreach. That contact layer is exactly what Revatto adds.

What does Revatto add over NMI's own setup?

Channels and a done-for-you team. Revatto detects every failed charge, enriches and normalizes the NMI transaction data, and runs a sequenced email + SMS + human outreach flow under your brand — the SMS and human follow-up a gateway never sends.

Does NMI tell me why a payment failed?

Yes — NMI returns a response code on a declined transaction (for example response_code 201, do not honor). Revatto normalizes that raw code into a standard failure category and maps it to the right recovery action.

Failed payment recovery for NMI

Quick answer

NMI is a payment gateway, so failed-payment recovery depends on the recurring-billing or merchant setup wired on top of it — at the gateway layer, a declined charge returns a response code and stops. Any retry cadence and any customer notification are configured by the merchant, not the gateway, and NMI sends no SMS or human outreach of its own. Revatto detects the failed charge, enriches and normalizes the transaction data, and runs an AI-timed email + SMS + human outreach sequence under your brand to drive the customer to update their card. It's done for you — human outreach recovers 60–85%+ — at 20% of the first recovered payment, $0 setup, $0 monthly, cancel anytime.

Key takeaways

NMI is a payment gateway — recovery behavior comes from the recurring-billing or merchant integration built on top of it, not from the gateway itself.
A declined charge returns an NMI response code (e.g. response_code 201, do not honor); any retry schedule and any customer notification are the merchant's to configure.
NMI sends no SMS, phone, or human outreach of its own, so even a well-configured retry setup leaves most failed payments uncontacted.
Revatto does not programmatically re-charge through NMI — recovery runs through customer outreach that drives the cardholder to update their card.
Revatto's wedge on NMI is detection, enriched failed-payment data, and an AI-timed email + SMS + human outreach sequence done for you — and you pay 20% of the first recovered payment, nothing on the rest.

The gap NMI leaves open

What NMI recovers on its own

NMI is a payment gateway and gateway adapter — it authorizes and processes the charge and returns a response code when one declines.
Retry timing and dunning are properties of the recurring-billing module or merchant integration wired on top of NMI, not of the gateway itself, so they vary by setup.
NMI provides no built-in SMS, phone, or human-led customer outreach for a failed payment — any notification is whatever the merchant configures.

NMI stops at: The decline arrives as a raw NMI response code with the customer scattered across the transaction record.Revatto adds: Revatto enriches and normalizes the failed-payment data so outreach knows exactly who to reach and why the charge failed.
NMI stops at: Revatto doesn't re-attempt the charge through NMI for you, so a silent re-charge isn't the recovery path.Revatto adds: Revatto runs managed multi-channel outreach and drives the customer back to update their card.

How Revatto recovers failed NMI payments

1
Detect the failureRevatto ingests the failed NMI transaction the moment a charge declines — no weekly gateway report to comb through.
2
Enrich the paymentRevatto normalizes NMI's raw response code (e.g. response_code 201, do not honor) into a standard failure category and resolves the customer behind the charge, so outreach is targeted instead of guesswork.
3
Reach the customerAn AI-timed sequence of email + SMS + a human recovery specialist contacts the customer under your brand — the SMS and human channels a gateway never provides.
4
Drive the card updateRevatto guides the customer to update their card on file — because Revatto doesn't programmatically re-charge through NMI, recovery runs through outreach, not a silent re-attempt.
5
Stop on successWhen the payment clears, Revatto ends the sequence automatically — no double-charge, no stray outreach.

How a NMI decline maps across stacks

A do-not-honor decline on NMI — ISO 05 (NMI surfaces this as response_code 201, do not honor). Recovery looks the same across every stack Revatto runs on — here is how the same issuer decision is named on each.
