# How to Set Up Shopify Workflows Using Mercuri API

### Use case: Set Up Cart Abandonment WhatsApp Reminder Workflow in Shopify Using Mercuri API

Cart abandonment reminders help re-engage customers who added items to their cart but didn’t complete their purchase. Follow the steps below to automate a WhatsApp reminder using **Shopify Flow** and the **Mercuri API**.

#### Steps to Create the Workflow

{% embed url="<https://youtu.be/D-U1pPcS358>" %}

1. Go to your **Shopify Admin Dashboard**.
2. From the left-hand side panel, click on **Apps**, then select **Flow**, or search for *Flow* using the app search bar.
3. Once the Flow dashboard opens, click on **Create Workflow** in the top-right corner of the screen.
4. You’ll be prompted to either **Select a Trigger** or **Browse Templates** — click on **Select a Trigger**.
5. You’ll now see the **workflow dashboard**. To start building your automation, select a trigger.
6. In the search bar, type **“Customer abandoned checkout”** and choose it from the list.
7. This trigger activates the workflow whenever a customer adds items to their cart but doesn’t complete the checkout process.
8. After setting the trigger, click the **“+”** button to add the next step.
9. Select **Action → Wait** (under Flow). Set the waiting time to **1 hour**.This ensures the WhatsApp reminder will be sent one hour after the cart is abandoned.
10. Click the **“+”** icon again below the wait step.
11. Select **Action → Send HTTP Request**.
12. In the flow action, configure:

* **HTTP Method:** `POST`
* **URL:** `https://api.mercuri.cx/v1/send_message`
* **Headers:**&#x20;

**Note:🔧 Changes to Make After Copy-Pasting the Code**

1. **Add Your Phone Number ID**

* Replace `"xxxxxxxxxxxxxxxxxxx"` corresponding to **phoneNumberId** in the code with the **Phone Number ID** you copied from the Mercuri Dashboard.

2. **Add Your Template ID**

* Replace `"xxxxxxxxxxxxxxxxxxx"` corresponding to **templateId** with the **Template ID** you copied from the Mercuri Dashboard.

[***Please click on this link to view the instructions for locating the Phone Number ID and Template ID.***](https://docs.mercuri.cx/features/introduction-mercuri-api/faqs)

3. **Add recipient :**

* Click the **Add Variable** button at the bottom-right of the body box, search for **phone number**, and select it.&#x20;
* This variable automatically fetches the customer’s phone number to send the cart abandonment message.

4. **Add Template Variables :**&#x20;

Based on your message template:

* Add the corresponding parameters and values so they dynamically populate for each customer.
* For this tutorial, we’ve included a single variable — the **customer’s first name**.\
  To add it:
* Click **Add Variable** at the bottom of the text box and search for **First Name**.
