Ach Payments Webhook Failing
ACH payment webhooks fail differently than card webhooks because ACH settlement is asynchronous — the webhook fires days after the transaction is initiated, and if your endpoint has changed or gone down in that window, you miss the event. Most ACH webhook failures in 2026 are missed events, not failed deliveries.
Why This Happens
- Configuration gaps between tools or services
- Missing integrations or manual workarounds that weren't designed to scale
- Changes in vendor behavior, pricing, or API that weren't communicated clearly
What To Check First
- Verify your current setup matches the vendor's latest documentation
- Look for recent changes — platform updates, new team members, configuration drift
- Check if the problem is consistent or intermittent (different root causes, different fixes)
When To Escalate
- The problem is costing you money or customers per week
- You've spent more than 2 hours on it without progress
- A vendor quoted you more than $500 and you're not sure if it's necessary
Dealing with this right now?
The fix: always build your ACH payment logic to handle both the webhook and a polling fallback. Query the payment status on a schedule (every 6 hours for the first 5 days) in addition to listening for the webhook. Stripe, Dwolla, and Plaid all support both patterns. This redundancy is especially important for ACH because the retry window is short — processors typically retry failed webhooks for 72 hours, not the 7 days they allow for card webhooks.
