# Finding a Rule's ID for Shopify Flow

Flow actions target a rule by its ID rather than its name. Here is where to find that ID, and why the name would not work.

**Short answer.** Every saved rule has a unique ID shown in two places on its edit page, a line under the page title and a Rule ID card in the sidebar, each with a copy button. You need it when building a Flow action such as Set a rule limit, Toggle rule or Reset repurchase counter, because those actions look a rule up by ID and never by name.

## Key takeaways

- The ID only exists once a rule has been saved at least once.
- It is available on every plan, and is not a Pro feature.
- The ID never changes, even if you rename the rule.
- Two rules are allowed to share a name, which is why a name cannot identify one.

## Why an ID and not a name

Rule names are not unique. Nothing stops you calling two rules "Wholesale
minimum", and for a human reading the Rules list that is often the sensible
thing to do, because they cover different collections.

A Flow action that matched on that name would have to pick one, and it would pick
silently. Targeting by ID removes the guess: either the action changes the rule
you meant, or it fails visibly with an error you can see in the Flow run log.

## Where to find it

Open any saved rule. The ID appears twice:

- A Rule ID line with a copy icon, just under the page header.

- A Rule ID card lower in the sidebar, with the same value and its own copy
button.

Either copy button puts it on your clipboard and confirms with a toast.

## Use it in a Flow action

**Open the rule you want to target and copy its ID.**

**In Shopify Flow's editor, add the action,** one of
[Set a rule limit](https://primemoq.app/help/automations/action-set-rule-limit),
[Toggle rule](https://primemoq.app/help/automations/action-toggle-rule) or
[Reset repurchase counter](https://primemoq.app/help/automations/action-reset-repurchase-counter).

**Paste the ID into the action's Rule field.**

If you imported a template, the same step applies. Templates arrive with a
placeholder in that field, described in
[Ready-made workflow templates](https://primemoq.app/help/automations/workflow-templates).

## Common mistakes

- Looking for the ID on an unsaved rule. It does not exist until the rule has
been saved once.

- Typing the rule's name instead. Flow actions match by ID only.

- Assuming a rename breaks the workflow. It does not. The ID is unchanged by
a rename, so an existing workflow keeps working.

- Copying from the wrong rule. Two similarly named rules are exactly the
situation the ID exists to disambiguate, so check the page you are copying
from. A duplicated rule gets its own new ID, covered in
Edit, duplicate and delete rules.

## FAQ

### Is the Rule ID the same as an order or API reference?

No. It is specific to the rule, a unique identifier for that rule inside Prime MOQ, and it does not correspond to anything in Shopify's own order or product numbering.

### Do I need Pro to see or copy a Rule ID?

No. It is available on every plan and on every rule type, because reading an identifier is not something worth gating.

### What happens if I paste the wrong rule's ID into a Flow action?

The action targets that other rule instead, and it will succeed, because the ID is valid. Check which rule you copied from before saving the workflow.

### Does duplicating a rule copy its ID as well?

No. A duplicate is a new rule and gets an ID of its own, so a workflow pointed at the original keeps affecting the original and never follows the copy.

**Best for:** Anyone building a Shopify Flow workflow that sets, toggles or resets a specific Prime MOQ rule.
