Differences between configuring Triggers and Actions

Square actions can be configured based on the available fields.

For Square triggers, you must create a new webhook subscription for each workflow in the Square Developer Dashboard. The following steps provide an outline of the setup process.

Creating a Square webhook subscription step-by-step

1. In a new tab on your browser, visit the Square Developer Dashboard: https://developer.squareup.com/apps

2. Sign into your account.

3. Under Applications, click on the Gray plus button if you have not created an app for MESA just yet.

4. Enter MESA Shopify as the Application name.

5. Then, click the Next button.

6. Next, you will be prompted to select what you will be building and who your audience is. Select whichever applies to you or feel free to Skip.

7. Afterwards, you will be taken to the Credentials page. In the left-hand side menu, locate Webhooks > Subscriptions. Click on Subscriptions.

8. Click on Production at the top of the page to toggle the button to Production.

9. Under Webhook subscriptions, click on the Add subscription button.

10. Go back to MESA. Locate your workflow with the Square trigger and click on Configure.

11. Then, click on the Copy icon next to the Webhook URL field.

12. Go back to the tab with the Square Developer dashboard open.

13. In the Webhook name field, enter the name of the MESA workflow trigger for simplicity.

14. In the URL field, paste the copied Webhook URL.

15. Leave the default API version as selected.

Under Events, please select the appropriate event that corresponds to your MESA trigger. For example, we have selected order.created for MESA's Order Created trigger.

Once you have selected the event, click on the Save button.

You are all set for that specific MESA workflow with the Square trigger. You will want to do this for every workflow that contains a Square trigger.

Refer to this guide for a full list of Square triggers and their corresponding webhook events.

Technical Notes

While our Square integration has extensive possibilities to achieve your workflow goals, there are a few important things to be aware of.

Our integration does not allow you to use Square as a third-party payment provider in Shopify.
Square orders cannot be automatically created in Shopify and linked with the original Square order when placed via Square. Vice versa, Shopify orders cannot be automatically created in Square and linked with the original Shopify order when placed via Shopify. Limitations between both services and their APIs prevent this currently.
