Downpay triggers

Downpay's triggers can be found in Shopify Flow when creating a new workflow under the Triggers menu.

Payment collection failure

The payment collection failure trigger can be used when collecting remaining payment and wanting to take action if payment fails. This trigger also contains a field that states the reason for the failure which can be used as a condition to have different actions based on the state.

Payment collection success

The payment collection success trigger can be used when collecting remaining payment and wanting to take action on payment collection success.

Payment authorization failure

The payment authorization failure trigger can be used to take action if payment authorization fails. This trigger also contains a field that states the reason for the failure which can be used as a condition to have different actions based on the state.

Payment authorization success

The payment authorization success trigger can be used to take action on payment authorization success.

Payment due in

Each order placed through Downpay has an associated due date for the remaining balance. Downpay comes with triggers for when orders are due. There are triggers for 24 hours, 48 hours, and 7 days before payments are due. These triggers, in addition to the default Payment Schedule is Due trigger, can be used to collect the remaining payment, or take another action depending on your use cases. For example, you could place a hold on a customer's card 48 hours before the order is due, and then fulfill the order knowing that payment is secured.

Downpay order created

The Downpay order created trigger starts Flows when an order is created that contains items using a Downpay purchase option.

Downpay actions

Collect remaining payment

This action will collect the remaining balance to the card on file on a Downpay processed order.

Authorize remaining payment

This action will authorize the remaining balance to the card on file on a Downpay processed order.

Authorization, also known as pre-authorization or a credit card hold, is an approval from the credit card issuer that confirms that the cardholder has sufficient funds to cover the cost of a transaction. The length of the authorization varies based on the payment provider and Shopify Plan. Learn more about authorization on Shopify.

Void authorization

This action voids an authorization on a Downpay order, ahead of it's expiry date.

Update order due date

This action changes the due date of an open Downpay order with a deferred balance remaining.

Add product to purchase option

This action removes a product from a purchase option.

Remove variant from purchase option

This action removes a variant from a purchase option. The Variant ID can be added as a variable through Liquid code that outputs the ID, as well as by using the Flow variable picker.

Customer Notifications

Send an invoice to the customer if payment fails

Use the action Send invoice under Shopify to customize an invoice and let customers know payment has failed and that they should pay their remaining balance to avoid delays.

Recipient email address variable: {{order.customer.email}}

Sender email address variable: {{shop.email}}

Order number: {{order.name}}

Email customers before the remaining balance due date

If you want to remind customers to pay their order, or that you will be automatically collecting payment soon, use this flow. Their are several trigger options in Downpay including Payment due in 1, 2, or 7 days

Order management

Send an email to internal teams if payment collection fails

Use the action Send internal email under Shopify Flow to send an email to a staff member if payment collection fails.

Send an email to internal teams when order is fully paid

When using deposits as a layaway payment option for customers, an email can be sent to an internal team when the final payment has been made to begin fulfillment.

Release fulfillment hold when order is fully paid

When using deposit plans with Downpay with the Days after checkout due date type, orders will have an on hold status. A workflow can be created to check for fully paid status and automatically release the fulfillment holds in order to display Unfulfilled as an order's status.

Release fulfillment hold when order is created

When using deposit plans with Downpay with the Days after checkout due date type, orders will have an on hold status. If you are shipping products out before full payment is received, you can release the hold on fulfillments automatically with this flow. This is a useful workflow for using Downpay for try before you buy.

Payment collection

Collect payment on due date

This workflow uses the Shopify trigger Payment schedule is due which is the date listed on the order payment details card.

Collect payment on fulfillment

This workflow uses the Order fulfill trigger and the Collect payment Downpay action.

Send payment reminder with invoice 7 days before due date, then 1 day before due date, then collect payment on due date

Send payment reminder with invoice then automatically collect payment 48 hours later

This workflow will trigger on releasing a fulfillment hold. This flow is only compatible with Downpay purchase options that use days after checkout as the balance due date. It will then:

• Send a reminder to customers that you will be collecting payment automatically from their card on file in 2 days
• Wait 2 days
• Attempt a charge on the credit card on file for the order

Payment authorization

Authorize payment when order is created

This workflow will authorize the remaining balance when an order is created. This may be useful for brand who ship products before collecting full payment, for example as a trial.

Void authorization

This workflow voids authorization on orders tagged with void.

• This workflow runs once a day and looks at the last 100 orders.
• The trigger schedule can be adjusted to suit the timing that works for you.
• The Get order data query can be adjusted for a different tag name or you can use it for specific orders with the query name:ordernumber (ex: name:1104)

Collect payment once tag has been added to an order

This workflow will collect payment once a tag has been added to an order.

For example, using Proofer app for sending your customers a proof before buying will append a tag to the existing order.

In this particular scenario, Flow is checking for a tag named "proof_accepted" which indicates that the customer has accepted the proof.

After that, it will attempt to collect the remaining balance.

One thing to note is that it is using the Wait block which will wait 1 day before collecting the payment since we do not know when exactly the customer will accept the proof.

If the customer does not accept it within 24 hours, an email will be sent indicating that the proof has not been accepted yet.

You can put different email title and body and adapt a real email address to which you want to receive the email to.

Update due date based on event date

Sometimes you may want to update the due date on an order based on some other data, such as a tag or a metafield set on the order by some other process - for example a shipping app. The following example flow looks at the tags on an order— in this case specifically for one that starts with "Due Date:" (for example, "Due Date: 2025-06-14"). The event date tag is set on the order at Order creation. This flow calculates a new date that’s 21 days earlier, and then sets it as the new due date. This is helpful if you want to trigger something like production, fulfillment prep, or a reminder three weeks before the order is due. If the due date tag isn’t there or isn’t formatted correctly, the system will return an error message so you know what’s missing.

This code can be updated up to your requirements and needs.
