Send an NPS survey using Delighted

Customer.io on Feb 13, 2018

If you don’t already have an account, you can sign up at https://delighted.com/.

Get your API Key

To send NPS surveys via API, you will need your API key. Your API key can be found in your Delighted account under Integrations > API. Only admins on your Delighted account can view the API key. If you’re not the admin, reach out to the person in charge with the Delighted account in your company.

Create a new campaign

Inside your Customer.io account, create a new campaign— event triggered or segment triggered depending on what should trigger the Delighted NPS survey sending.

In our example we’ll use the “Upgraded” trigger segment and a 7 day delay.

Add your webhook action

Now that we set the stage, we’re ready to add the webhook action. We’ll call our webhook “Upgraded: 7 days survey.”

After adding the webhook, click Add Request.

Customize your webhook headers

Next to POST add your Delighted API key followed by the People endpoint. The format needs to be:

https://[API-key]@api.delighted.com/v1/people.json

For example:

https://CMj7SuKdy4w0oVdAqXsE5hxXxXxXxXxX@api.delighted.com/v1/people.json

Customize your webhook body

For our survey we’ll use the content from

Customize the fields however you like; only the email is mandatory. The others are at your discretion, and you can find more information about them in the Delighted API docs.

At this point, your webhook should look like this:
