Failed payments
On Friday the finance lead asks which Mollie payments failed this week. Memtro lists them with amount, method, description and customer, beside the ones that expired, so the team can contact each customer before the weekend.
Mollie + Memtro
Which Mollie payments failed, what a customer has paid and when subscriptions next charge.
Connect Mollie with a website profile's API key and Memtro reads that profile's payments with amount, status, method and amount refunded, customers, subscriptions with next payment date, and the refunds on one payment. It reads on demand and there is no hourly sync. When you ask, and once an administrator has granted the action by name, it can create, change or delete a customer, create a payment link, cancel an open payment or a subscription, and refund a payment or cancel a pending refund. Refunds move money back to the customer and become permanent after about two hours.
In Memtro
What you can do with Mollie in Memtro
Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right Mollie tool, reads what it needs, and answers with the source cited.
What it does
- 01Payments newest first with amount, status, method, description, customer and amount refunded
- 02Payment status such as open, paid, failed or expired, to see what did not come through
- 03Customers with name, email, locale and created date, and subscriptions with amount, interval and next payment date
- 04The refunds made on one payment, with amount, status and date
- 05When asked and granted, refunds a payment fully or partly, moving money back to the customer, or cancels a refund while it is still queued or pending
- 06When asked and granted, creates a payment link to share, permanently cancels an open payment or a subscription, and creates, changes or permanently deletes a customer, which also cancels its mandates and subscriptions
Acts when asked
When you ask it to
These tools change something in Mollie. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.
- 01Create a customer record in Mollie
- 02Refund a payment, fully or partly, to the customer
- 03Cancel a refund that is still queued or pending
- 04Create a payment link to share with a payer
- 05Cancel a payment that is still open
- 06Cancel a customer's subscription so no further charges are taken
- 07Change a customer's name, email or locale
- 08Delete a customer, cancelling its mandates and subscriptions
Events
When it happens
Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in Mollie, choosing the same kinds; the tab shows Mollie's own steps. Each event can start a job, with the event as its input. Mollie signs every delivery, and one whose signature does not check out is refused before it is read.

In practice
Ask it like you would a colleague
Once Mollie is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.
Mollie + MemtroWhich payments failed this week?
Did the payment from Acme come through?
Which subscriptions are active, and when does Brightwave Ltd next pay?
Refund 20 euros of Northwind's last payment
Cancel Globex's monthly subscription
A partial refund
Sara Lindqvist asks Memtro to refund 20 euros of Northwind's last payment for a damaged item. Memtro finds the payment, refunds that amount with the description she gave, and Mollie sends it back to the customer's card. She has about two hours to cancel it before it is final.

FAQ
Questions
Can Memtro change anything in Mollie?+
Only when you ask, and only what it has been granted: create a customer record in Mollie; refund a payment, fully or partly, to the customer; cancel a refund that is still queued or pending; create a payment link to share with a payer; cancel a payment that is still open; cancel a customer's subscription so no further charges are taken; change a customer's name, email or locale; delete a customer, cancelling its mandates and subscriptions. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.
Who can use a Mollie connection?+
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Does Memtro store my Mollie data?+
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded.
How do I connect Mollie?+
API key. You need a Mollie website profile: an API key belongs to one, so connect once per profile.
Can Mollie start a job?+
Yes. Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in Mollie, choosing the same kinds; the tab shows Mollie's own steps. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
