Shopify Custom App
Shopify is a commerce platform that allows anyone to set up an online store and sell their products. The Custom App connector uses your own Shopify app credentials for authentication, giving you full control over API scopes. Weld syncs your Shopify data into your data warehouse and supports Reverse ETL to push customers and metafields back to Shopify.

Prerequisites
To connect your Shopify account to Weld, you need:
- Access to a Shopify store account.
Step 1 — Create a Shopify Custom App
- Log in to your Shopify developer account
- On the top right corner click Create app
- Using the "Start from Dev Dashboard" option, name your app and click Create
- On the next screen set the scopes in the "Access" section. The tables that Weld syncs are all accessed through the "Admin API", so only scopes from that API are needed.
- After this, click Release. Optionally give a name and description to the version.
- Once the version is released, click on the Home tab on the left.
- Here, on the right side you will find an Install app button. Click it and follow the instructions.
- Once the app is installed, you are ready to connect it to Weld.
Step 2 — Connect to Weld
- In Weld, select the Shopify Custom App connector
- In the connector form add your Client ID, Secret and Store ID.
You can find the Client ID and Secret in the app's settings page on the dev dashboard.
The store ID must be for the store where you installed the app in the previous step. You can find it in the URL of the store admin page. It looks like the following:
https://admin.shopify.com/store/your_store_id/... - Click Connect
Step 3 — Data to Sync
- Select the tables you want to sync. All available tables are listed with their sync mode (incremental where supported).
- You can view the schema, remove columns, or hash sensitive information.
- Click Next to continue.
Step 4 — Configure Sync
- Choose a schedule type (Independent or Orchestration).
- Select how often you would like the data to sync.
- Click Start Initial Sync to begin syncing.
Setup Guide - Reverse ETL
Shopify Reverse ETL allows you to sync data on a schedule from your warehouse into Shopify. You can sync data from your SQL models, dbt models, or raw warehouse tables to the following Shopify objects:

Step 1 — Choose Destination
- Navigate to Reverse ETL in the sidebar and click + New.
- Search for Shopify and select your connected Shopify Custom App account.

Step 2 — Map Data
- Select your source — a SQL model, dbt model, or raw table/view from your warehouse.
- Select your destination object (
customerormetafield).

- Sync mode is set to Upsert — if a matching record is found in Shopify it will be updated, otherwise a new record will be created.
- Set up the identifier — choose which source column matches the Shopify
idfield. - Map the columns from your source to the corresponding fields in Shopify.

Your source should have one row per object for Reverse ETL.
For example if you are performing a reverse ETL to the customer object then you should have one row per unique customer.
Requires Primary key.
Step 3 — Schedule Sync
- Choose a schedule type (Independent or Orchestration).
- Select the sync frequency.
- Click Start Sync to begin.
