End Functionv1.2Welcome
Nutritics API allows you to leverage the power of the world's favourite nutrition engine in your own app, program or website. Integration requires you to either be or to hire a developer. The API can be accessed from any programming language which can connect to the internet.
Most common uses for our API
- Search our vast international databases
- Analyse recipes from your own app or platform
- Analyse a diet from your own app or platform
- Generate a meal plan from your own app or platform
- Control Nutritics user data
Introduction
Working with the API is very straight forward. All requests are made via HTTPS URLs. Each URL contains a set of parameters which specify the data you wish to retrieve. The data is always returned in JSON format.
For example, here's a simple request which searches our database for the keyword "bananna"
https://[USERNAME]:[PASSWORD]@https://www.nutritics.com/api/v1.2/LIST/food=banannaAPI explorer
You can use our powerful API explorer to build and test your requests before deploying them. The explorer will automatically generate a basic connection script in the most common coding languages to get you up and running quickly.
Syntax for requests
https://{USERNAME}:{PASSWORD}@www.nutritics.com/api/{API_VERSION}/{FUNCTION}/user={USER_ID}&{OBJECT}={ID OR GROUP}&[other parameters...]Parameters after the last forward slash can be listed in any order.
Please note, the following characters are in use by the API engine and may break certain requests unless URL encoded:
{ ' } / \ | ¦ ~ > < + - , : " [ ]Request Methods
Nutritics API supports both HTTP GET and HTTP POST methods. For simplicity, the GET method is used throughout our documentation. Please note however that HTML GET maximum URL length is 2048 characters so you will need to use the POST method if you need to make very long requests.
Required Parameters
The following parameters are required on all requests.
{USERNAME}:{PASSWORD}
Your developer username & Password{API_VERSION}
Currently v1.2{FUNCTION}
The action you wish to perform. Read more about functions.
function description LIST Search and retrieve a list of Nutritics Objects or any set of data within them CREATE Create a new Nutritics Object and return it's calculated values MODIFY Edit a Nutritics Object DELETE Remove a Nutritics Object {OBJECT}
The type of data you wish to work with. A description of each of our core objects is listed below. Read more about objects.
object parent description user dev A Nutritics account client user A customer of a Nutritics user food user A base food or ingredient recipe user Multiple foods are combined to form a recipe activity system An exercise or physical action dietlog client A list of foods a client has eaten over a given period mealplan client A special diet prescribed by a user for their client Return Data
All requests return a stripped Nutritics object in JSON format. The following attributes are appended to all returned objects
Attribute Type description status int(3)int: A numeric value without a decimal Response code of your request msg stringstring: Letters, numbers, or other types of characters A message containing errors or warnings regarding your request. queryTime intint: A numeric value without a decimal Number of miliseconds the server took to process your request id intint: A numeric value without a decimal Returned only with 404 errors to specify the nutritics ID of the missing component. warning stringstring: Letters, numbers, or other types of characters Returned only when something has gone wrong but your request was still processed successfully. Debugging
You may append &debug=1 to any request to see a breakdown of all the data the API is using to calculate its response to your request. This can give useful insight when debugging your application.
Nutritics Objects
Data is sent and received from the API in Nutritics objects. The tables below detail all available parameters for objects. Note that all functions return a stripped object, which will not contain all available fields. If you need fields which are not returned by default, you may use the DETAIL function to specify these.

- Recipes
- Clients
- Diet Logs
- Meal Plans
- Nutrients

Response Codes
Code Name Description 200 Success Everything worked as expected. 400 Bad Request The request was unacceptable, often due to missing a required parameter. 401 Unauthorized Your username or password are incorrect 402 Limit Reached (check your account status) 404 Not Found No object found under the specified filters. 429 Too Many Requests Too many requests hit the API too quickly. We recommend an exponential backoff of your requests. 500, 502,
503, 504Server Errors Something went wrong on our end (check the API status)
Allergen mapping recommendations
To minimise risk of allergen misinterpretation, Nutritics recommend mapping allergens from the allergens attribute (e.g &attr=allergens). To parse and map the results, use a LIKE search for the cereal species (wheat, oats, barley, rye) and an exact match for 'Gluten'. In no scenario should the presence of a cereal species invoke a gluten tag automatically in the destination system. Mappings should be 1:1.
Nutritics sends…
Activates
Trigger word:
Oats, gluten-oats
Oats
%LIKE match for ‘Oats’ '%Oats%'
Wheat, gluten-wheat
Wheat
%LIKE match ‘%Wheat%’
Barley, gluten-barely
Barely
%LIKE match ‘%Barley%’
Rye, gluten-rye
Rye
%LIKE match ‘%Rye%’
Gluten
Cereals Containing Gluten
Exact match for ‘Gluten’
Notes:
- We have used the term %LIKE match which is a SQL term and should be understood as such. The matching logic and the underlying technology can be different but the principle demonstrated above should be considered to avoid misinterpretation of our allergen data.
