Customer API introduction

The Nutritionist Pro customer API is a REST API that lets your own software read the data you have created in Nutritionist Pro online. Use it to show recipes and nutrition on a website, send nutrient values to a point of sale, or keep an ERP or menu system in step with your account.

Read-only by design​

The API is read-only. Every endpoint is a GET request. It cannot create, edit, or delete anything, and it cannot change account settings. To change your data, keep using the Nutritionist Pro online application.

What it returns​

The API returns the same data you can see when you sign in to Nutritionist Pro, including data shared with you by other users on your account.

  • Recipes, with servings, instructions, allergens, nutrients, and ingredient lines.
  • Recipe books, and the recipes in each book.
  • Ingredients, one at a time by ID.
  • Labels, with the serving, statements, and nutrient values saved on each label.

Three kinds of data are left out:

  • Items that are still in Draft status.
  • Data that belongs to other accounts.
  • The Axxya ingredient database as a list. An Axxya database ingredient can be read only when it is used in one of your recipes. See Ingredients.

How it works​

Every request is an HTTPS GET to the base URL, with your API key in the Authorization header. Responses are JSON.

curl -H "Authorization: Bearer <API_KEY>" \
  "https://dev.nutritionistpro.com/v3/customer/recipes?limit=2"
{
  "status": true,
  "code": 200,
  "data": [

      "updated_at": "2026-05-19T09:02:47Z"
    }
  ],
  "meta": { "total": 1, "limit": 2, "offset": 0 }
}

Who can use it​

The API is available to Nutritionist Pro online accounts with an active subscription. Trial accounts cannot create an API key. Each user can make 500 requests per day; see Errors and limits.
