Hey ​@fxi 

Do you know how to utilize Send Email API endpoint? This allows you to send pre-designed templates stored in Klaviyo to specific recipients with dynamic data (like email, first name, and metadata)

so basically endpoint url should be - https://a.klaviyo.com/api/v1/email-template/pTEMPLATE_ID]/send

Method: Post 

and the payload should be something like this

{
  "to": "customer_email@example.com",
  "context": {
    "first_name": "John",
    "coupon_code": "SAVE20",
    "rule_description": "This coupon is valid for one-time use only and cannot be combined with other offers."
  }
}

I hope this helps and thank you for sharing your question here in the community.

Cheers

Arpit

  }
}

Hey,

isn’t the `send` endpoint heavily restricted?

Furthermore, it gives me: 

{

    "status": 403,

    "message": "You must specify an API key to make requests."

}

Even though I authenticated myself in the headers with `Authorization` and my Klaviyo-API-Key!
