Two cards for one failed payment
A retried webhook left two cards on the board and two people writing to the same LemonSqueezy customer.
BoldBellowsLemonSqueezy to Trello automation that builds cards worth working from
LemonSqueezy to Trello automation that gives each failed payment, refund or cancellation one card with a checklist, then finds it again after it moves
LemonSqueezy to Trello automation turns the billing events that need a person into cards with an owner, a due date and the steps to follow. A Trello card moves from list to list, so an order stored only in its title gets lost, and LemonSqueezy retries webhooks within minutes. BoldBellows reads the webhook for its event name, resource ID and test-mode flag, answers the webhook immediately and only proceeds once the order status is paid, then builds one card and keeps the order ID in a custom field that can always be searched.

Chapter 01 the lost-card problem
A card whose order nobody can find gets created twice
Cards move. By the time LemonSqueezy sends the recovery for a failed payment, the save-the-customer card may sit in Waiting for Reply or have been archived, and a search by title finds nothing. The sync makes a second card, and a helper chases a customer who already paid.
The update could not find the LemonSqueezy card, so it made another.
A card nobody could find
With LemonSqueezy to Trello in place, the title was edited during triage, so the next update could not locate it.
A checklist retyped every time
The steps a refund needs were typed in by hand on each LemonSqueezy card, and one was always skipped.
Before
After
Before
- Every hook delivery becomes a write
- The order is stored in the card title
- A moved card cannot be found
After
- Identity is fixed by a LemonSqueezy order-ID custom field and never re-guessed
- The order ID is kept in a custom field
- The board is searched for it before anything is created with LemonSqueezy to Trello
Chapter 02 How it works
How a LemonSqueezy event becomes one Trello card with a checklist
Every step has a check before it, so a fault stops the run instead of spreading.
Check it is real and in scope
The LemonSqueezy notice is validated, the underlying record is read, and only a qualifying order event moves on.
Search the key, then build
With the signature verified and the order ID saved, the custom field is searched; if the case is unseen, the list, due date, labels and checklist are prepared from a written map.
Place the LemonSqueezy card and keep its ID
The card is created or refreshed, the checklist is finished, and the card ID is saved against the LemonSqueezy event.
Behaviour of LemonSqueezy and Trello we design around
- Now part of Stripe: Stripe acquired LemonSqueezy in 2024, so the brief confirms your store's current payout and setup details before anything is built.
- Custom fields on cards: Trello custom fields add structured data to a card, such as text or dates, so the order ID has a home that can be searched.
- Lookups before retries: A LemonSqueezy order-ID custom field is the route's way of asking Trello whether the work is already done.
Chapter 03 What ships in the build
The LemonSqueezy Trello route, one capability at a time
Signal answers whether this should happen. Control answers what exactly gets written. Reconcile answers whether it is still right next month.
Intake rule reader
Interprets the LemonSqueezy payload against the intake rule and stamps the decision on the ledger.
Stable identity ledger
Pairs every LemonSqueezy record with its Trello counterpart in a ledger you can read.
Map change log
Records every change to the field map, so a later question about a Trello value has an answer.
Card and checklist builder
Creates the card with its list, labels, due date, members and checklist from the LemonSqueezy event.
Custom-field matcher
Keeps a repeat from becoming a second card by checking a LemonSqueezy order-ID custom field before the write.
List routing matrix

Chapter 04 Who this fits
Where design asset sellers on LemonSqueezy need to work save-the-customer and refund cases on a Trello board
If a board tracks the work, each LemonSqueezy case must be one card that stays findable.
Support lead
"Every failed payment should be a card with a deadline."
Cards open with a due date from the LemonSqueezy event.
Team member
"Give me a checklist I can use." with LemonSqueezy to Trello
Steps are built from the Trello event type, not retyped.
Board owner
"Do not let cards duplicate."
In the LemonSqueezy to Trello route, the custom field makes an update find the original.
SaaS founder

Indie developer
"Keep the board simple."

Chapter 05 The options
Where notification emails and zaps stop, a card-and-checklist builder begins
Each can add a card. Only one can find it again.
| Question | Notification emails | A typical trigger-and-action zap | A BoldBellows card-and-checklist builder |
|---|---|---|---|
| What starts the work | The next person to look | Each delivery, repeats included | Rule-approved events, logged with the reason |
| How identity is decided | Guessed from context | A single field treated as the key | A custom field holding the order ID |
| What reaches Trello | A few fields, entered late | A copy without context | One LemonSqueezy card with list, labels, due date and checklist |
| After an uncertain result | Open both apps and compare | Runs again from the start | Matches on a LemonSqueezy order-ID custom field, then repairs or holds |
A late arrival
Events that reach the route after a newer one are recognised by timestamp and routed for review instead of applied, in the LemonSqueezy to Trello route.
The LemonSqueezy card was moved, archived or its custom field was removed
The board is searched by order ID, and if the field is gone the case waits with a clear reason instead of making a twin. Finding the card comes first: a LemonSqueezy order-ID custom field is searched, the hit is compared, and only then is an action chosen.
Nothing is written to Trello until a LemonSqueezy order-ID custom field is defined and stored for each card.

Chapter 06 The process
Six steps from LemonSqueezy cases to cards that stay findable
Each of the six steps has an output you can read, not just a status update.
-
About 30 minutes
Decide which events become cards
We list the LemonSqueezy events that earn a Trello card and the list each one belongs on.
-
Access review
Approve access
Together we approve what the route may read in LemonSqueezy and where it may write in Trello.
-
Most of the project
Agree lists, labels and fields
In the LemonSqueezy to Trello route, the custom field, list rules, labels, due-date logic and checklist templates are written down and signed off.
-
Before you review
Stress the edges
Late deliveries, doubled events and partial failures are simulated in a test Trello and the results reviewed with you.
-
Handover day
Launch with notes
We switch the route on at a checkpoint you approve and leave you with written notes on how it works.
-
About 30 minutes
Post-launch review
We go through the exception list and the checkpoint log with you and agree what, if anything, needs a change.
Chapter 07 Turnaround
Timing for the Trello build
The clock starts once LemonSqueezy and Trello access are approved.
Signal
3 to 5 business days
Control
5 to 8 business days
Reconcile
8 to 12 business days
Chapter 08 Getting started
What you supply to begin
Approved, revocable access to the LemonSqueezy side
Access to the Trello board and permission to add a custom field
Access to the LemonSqueezy account that holds the records in scope
Your expected behaviour for edits, cancellations and repeats
The hours when changes to Trello are safest to release
Records or dates that the route should ignore
Chapter 09 Trust
Narrow permissions, narrow payloads, nothing patched
Only agreed LemonSqueezy data leaves, and it goes to one named place in Trello.
Untouched core, documented edges
Both LemonSqueezy and Trello are used as their own documentation describes; no workaround reaches into their internals.
Scoped, revocable access
Scopes are reviewed with you before launch and again at handover.
Nothing extra travels
The route forwards what was agreed and ignores the rest, so Trello never becomes a second copy of everything in LemonSqueezy.
Proof before repetition
Nothing is created twice: a missing confirmation triggers a search of Trello by a LemonSqueezy order-ID custom field before any further write.
Minimal logging
Logs hold identifiers, times and error types, not your customer content.
Full handover
Handover includes the rules, the owners and the repair steps in one PDF.
"A card moves, so the build stores the order ID where it can always be searched, not in the title."

Chapter 10 In their words
What BoldBellows clients say
Verified reviews from business owners who use BoldBellows automations every day, from marketing and data to support and operations.

AI Content & Social Media Automation
Our marketing agency couldn’t keep up with content. BoldBellows set up an AI content engine that writes blog posts and captions and even designs our social media creatives.

Late payments dropped sharply, and our accounting team finally has time for strategy instead of repetitive admin. Worth every penny.
AI Data Entry & Reporting Automation

The reports are clean, visual and easy to read, and our managers rely on them for quick decisions. Human error is gone and our numbers are more accurate across the board.
Chapter 11 Questions
Trello cards from LemonSqueezy: questions from support and success teams
A handful of honest answers before you spend anything.
We tried a LemonSqueezy to Trello Zapier flow; what changes?
A zap can provide a card created for every case. It is not built to find a card again after it moves, build a checklist from the event or place a case on the right list. The work here is the judgment around the connector, not the connector itself.
How do I create a Trello card from a failed LemonSqueezy payment?
Each LemonSqueezy event that qualifies arrives by webhook, and the route verifies it, searches the custom field for its order ID and creates one card with list, due date, labels and checklist.
What if the LemonSqueezy card has moved to another list?
The route searches by the custom field, not the title or the list, so the LemonSqueezy card is found wherever it now sits.
Does a recovered payment change the existing Trello card?
Yes. Because the order ID matches, the card is updated and no second card is made.
Can the checklist depend on the type of case in the LemonSqueezy to Trello route?
Yes. A written map gives a failed payment, a refund and a cancellation their own steps.
Can refunds and cancellations use different boards?
Yes. Board and list are picked from the Trello event type and plan using a table written with you.
Who closes the card when the customer is saved?
A recovery event moves the card to the done list automatically, with a note of when the payment succeeded.
Will you map custom fields as well in the LemonSqueezy to Trello route?
Absolutely. Nothing reaches Trello until the LemonSqueezy Trello field mapping service has your approval on the page.
Is a tailored workflow possible, or only a standard one on the LemonSqueezy to Trello route?
Yes. Anything you can state as a rule can become part of a custom LemonSqueezy workflow for Trello. That includes LemonSqueezy Trello integration consultant advice, from $415.
What happens if LemonSqueezy or Trello changes something later?
You get a list of the interfaces we rely on. When one shifts, the affected records hold and you are told. Later maintenance is quoted on its own.
