Custom AppSubscriptions

Automating subscription access with a custom Shopify app

An online dog-training brand's course access depended on customer tags managed by hand. As subscriptions scaled, the manual process broke down. We built a custom app that handles every state change automatically — including a 30-day grace period after cancellation.

Absolute Dogs — online dog training at scale

Absolute Dogs is an online dog-training brand selling courses and memberships. Customer access to training content depended on customer tags applied when someone purchased a course or active membership.

As the customer base grew, managing those tags by hand — as people bought, upgraded, or cancelled — became unworkable. And lapsed subscribers needed their access removed automatically after a grace period, like a streaming service, with zero staff involvement.

The challenge

Manual tag management that couldn't scale

Course access was entirely dependent on customer tags. The logic was right, but the execution — manual tagging by staff — couldn't keep up with a growing subscription base.

01

Manual tagging unworkable at scale

Every purchase, upgrade, or cancellation required a staff member to manually update customer tags. At scale, this was both time-consuming and error-prone.

02

Lapsed subscribers keeping access

When a subscription was cancelled, there was no automated process to remove course access — lapsed subscribers remained tagged, giving them continued access indefinitely.

03

Delay between purchase and access

New subscribers sometimes waited hours for their tags to be applied, creating a poor first impression at the moment of highest excitement about their purchase.

04

No systematic grace period logic

Access needed to be maintained for 30 days after cancellation, like a streaming service — but there was no mechanism to time-limit that access and remove it automatically.

The constraint

Shopify has no native purchase-to-access logic

Shopify has no native way to grant or revoke course access based on purchase, or to time-out access a set period after a subscription is cancelled. Customer tags must be managed via the Admin API, triggered by order and subscription events.

  • Shopify's native customer tag system has no conditional logic or event triggers built in.
  • Subscription lifecycle events (activate, cancel, pause, renew) are not directly surfaced to theme code.
  • Grace period logic — time-limited access after cancellation — requires a scheduled process with no native Shopify equivalent.

The approach: build a custom Shopify app that listens to order and subscription webhooks and applies the correct tag logic automatically at each state change.

Our solution

One custom app, zero manual tagging

UpSolite built a custom app that automatically adds, removes, and updates customer tags when an order is placed, driven by which course or membership was purchased — and automatically removes access 30 days after a subscription is cancelled, like a streaming-service grace period.

  • Listens to order and subscription lifecycle webhooks — activated, cancelled, paused, renewed.
  • Applies or removes the correct customer tags instantly at each event — no delay, no manual step.
  • 30-day access grace period after cancellation: tag is retained for 30 days, then automatically removed.
  • Access logic is encapsulated in one owned app — maintainable, auditable, and extendable as the product range grows.

Cancellation grace periodRetention logic

When a subscription is cancelled, the app retains the access tag for exactly 30 days, then removes it automatically — like a streaming-service grace period, with zero staff involvement.

Approach & timeline

Requirements-first, then event-driven build

Requirement-driven custom build: mapped every purchase-to-access rule and cancellation grace period scenario first, then implemented event-based tagging with a scheduled grace period process — covering all subscription lifecycle states before launch.

Common questions

What a custom access-automation app actually involves

Questions we often hear before a subscription access or custom app build.

We implement webhook retry logic and event logging. If a webhook fails to deliver, the app retries with exponential backoff. All events are logged so any missed action can be diagnosed and replayed.
Yes. The tag logic is driven by the product purchased, so each course or membership tier can have its own access tag — the app handles any number of products and tag combinations.
We run a backfill script to audit existing subscribers and apply the correct tags based on their current subscription status before the app goes live.
The app integrates via Shopify webhooks. As long as the subscription platform sends cancel events through Shopify or via webhooks, the grace period logic applies.
Access logic that works itself

Still managing course access by hand?

Whether it's subscription tagging, access grace periods, or purchase-triggered automation — let's build the custom app that removes the manual work entirely.
