Connect Shopify to Avis Boost
Shopify Flow sends the customer to Avis Boost when their order is fulfilled, without Zapier. The review request goes after shipping, not at payment.
What you need
- A Shopify Grow, Advanced or Plus plan: the "Send HTTP request" action of Flow is not available on Basic.
- The free Shopify Flow app.
- The phone number asked for at checkout, to send by text message.
- Your Avis Boost address: in your space, Account > Integrations.
When the text message goes
Flow tells Avis Boost when the order is fulfilled (shipped), and the text message goes following the sending delay of your establishment.
The steps
-
Step 1
Copy your Avis Boost address
In your Avis Boost space, open Account > Integrations, click "Get my address", then "Copy". Keep it to yourself: anyone who knows it can add contacts.
-
Step 2
Create a workflow
In your Shopify admin, go to Apps > Flow and click "Create workflow".
-
Step 3
Choose the trigger
Click "Select a trigger" and choose "Order fulfilled".
-
Step 4
Add the sending to Avis Boost
Click "+", then "Action" and "Send HTTP request". HTTP method: Post. URL: your Avis Boost address. Headers: the key Content-Type with the value application/json. Body: copy the text below as it is.
{ "first_name": {{ order.customer.firstName | json }}, "last_name": {{ order.customer.lastName | json }}, "phone": {{ order.phone | default: order.shippingAddress.phone | default: order.billingAddress.phone | json }}, "email": {{ order.email | json }} } -
Step 5
Set error handling
For client errors (4XX responses), choose "Ignore": an order without a valid mobile or email should not be retried for 24 hours.
-
Step 6
Turn on and test
Give the workflow a name, click "Turn on workflow", then fulfill a test order. The result shows in the recent runs of Flow, and the customer in your Avis Boost contacts.
The fields to send
Write the field name exactly as on the left. A mobile number or an email is required, the rest is optional.
| Field | Shopify data |
|---|---|
first_name |
order.customer.firstName |
last_name |
order.customer.lastName |
phone |
order.phone, otherwise the phone of the shipping or billing address |
email |
order.email |
Good to know
Create my account- An order shipped in several parcels triggers the workflow several times: Avis Boost recognizes the customer and only writes once.
- Without Grow or a higher plan, use Zapier: the Shopify "New Fulfilled Order" trigger, then the "Webhooks by Zapier" action (see the Zapier guide). The Shopify app requires a paid Zapier plan there.
- To write to customers in German or French, add "locale": "de" or "locale": "fr" to the body. Without it, the text message goes in the default language of your establishment.
