How Do I Add Customers to Feedspace via an Incoming Webhook?

Back

Last updated on September 10, 2026

Overview

The Incoming Webhook option lets your own software or external systems send customer data directly to your Feedspace workspace. Every time a POST request is sent to the Feedspace contacts endpoint with your API credentials, Feedspace adds or updates that customer in your list automatically.

This is useful if you want customers to be added in real time, for example, after a purchase, a signup, or a support ticket is resolved.

Before You Start

You need developer access or a way to send HTTP POST requests from your system.
Your request must use Basic Auth (Base64-encoded credentials).

Steps

Step 1: Open the Customers page

In the left sidebar, click Customers under the Workspace section.

In the modal, click the Incoming Webhook tab.

Step 4: Copy the endpoint

Click Copy next to the Endpoint to copy the URL. Every workspace posts to the same endpoint, so it is your API Key and Secret Key that identify yours.

Step 5: Encode your credentials

Follow the authentication instructions shown on the tab to encode your credentials using Base64. Your API Key and Secret Key are under Automation, then API.

Step 6: Send the POST request

Send a POST request from your system to the endpoint with a JSON body. The email field is required. All other fields are optional:

{
  "email": "customer@example.com",
  "name": "Jane Smith",
  "phone": "+1234567890",
  "company": "Acme Inc",
  "country": "US",
  "state": "California",
  "city": "San Francisco",
  "zipcode": "94103",
  "tags": ["vip", "enterprise"]
}

Common questions

Is the incoming webhook the same as an outgoing webhook?

No. The incoming webhook on the Customers page receives data FROM your system to add customers. Outgoing webhooks, found in the Automation tab, send data FROM Feedspace to your system when events like new reviews occur.

What happens if I send the same email twice?

If a customer with that email already exists, Feedspace updates their record with the new values from the request instead of creating a duplicate.

Troubleshooting

My POST request is returning a 401 error

A 401 error means your authentication credentials are incorrect. Make sure you are using Basic Auth with your credentials correctly Base64-encoded as shown in the Incoming Webhook tab instructions.

Customers are not appearing after I send the request

Check that your JSON body includes the email field with a valid email address. Requests without a valid email are rejected and the customer will not be added.

What you can do next

Test your webhook by sending a single POST request and checking if the customer appears in the Customers list.
Set up a form automation to send review requests to customers as they are added via webhook.
Use the outgoing Webhook feature in the Automation tab to receive notifications when a review is submitted.
