Testing access to the Webservice

Now that your access key is generated you can test your store’s webservice, its endpoint is located in the /api/ uri at the root of your installation of Prestashop.

Accessing /api/

The quickest way to test your API is to use your browser:

Browser prompt

The shop should prompt you for a username and a password to enter. The username is the authentication key you created and there is no password to enter. If no permission has been set for the key, than the browser will keep asking you to enter the key indefinitely.

Include key in url (risky)

The second way to access the API is to include your access key in the url, this will prevent you from entering any user name. Here is an example, assuming your access API key is UCCLLQ9N2ARSHWCXLT74KUKSSK34BFKX:

This method might be convenient for development but very risky as you expose your API key directly in the url, so anyone able to see (or hack) your browser history or access logs would be able to get your key. This should never be used on a production shop.

The best way to authenticate your API calls is to use an Authorization header, this way you don’t expose your API key directly but a base64_encode compute of your user:password couple. Although PrestaShop API only has a user with empty password, so in order to compute your authorization key you can do as follows:

$apiKey = `UCCLLQ9N2ARSHWCXLT74KUKSSK34BFKX`;
$authorizationKey = base64_encode($apiKey . ':'); // VUNDTExROU4yQVJTSFdDWExUNzRLVUtTU0szNEJGS1g6

Then you can use this value in your request header:

Key Value
Authorization Basic VUNDTExROU4yQVJTSFdDWExUNzRLVUtTU0szNEJGS1g6

To test/call your APIs we recommend you use an API client such as Insomnia or Postman, it is easier to call the APIs than with a browser, you can easily switch with HTTP methods, and it’s easier to set request parameters and headers.

As you noticed no password nor authentication process is required to access the APIs which is why you need to be extra careful with your access key rights and how (and to whom) you disclose them.

Available resources

The /api/ URL gives you the root of all the resources, in the form of an XML file. Here is an example of what you should see if you authorized full access to addresses, images and products resources:

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
    <api shopName="Prestashop">
        <addresses xlink:href="http://example.com/api/addresses" get="true" put="true" post="true" delete="true" head="true">
            <description xlink:href="http://example.com/api/addresses" get="true" put="true" post="true" delete="true" head="true">
            The Customer, Brand and Customer addresses</description>
            <schema xlink:href="http://example.com/api/addresses?schema=blank" type="blank"/>
            <schema xlink:href="http://example.com/api/addresses?schema=synopsis" type="synopsis"/>
        </addresses>
        <images xlink:href="http://example.com/api/images" get="true" put="true" post="true" delete="true" head="true">
            <description xlink:href="http://example.com/api/images" get="true" put="true" post="true" delete="true" head="true">
            The images</description>
        </images>
        <products xlink:href="http://example.com/api/products" get="true" put="true" post="true" delete="true" head="true">
            <description xlink:href="http://example.com/api/products" get="true" put="true" post="true" delete="true" head="true">
            The products</description>
            <schema xlink:href="http://example.com/api/products?schema=blank" type="blank"/>
            <schema xlink:href="http://example.com/api/products?schema=synopsis" type="synopsis"/>
        </products>
    </api>
</prestashop>

Resource schemas

You can also see that each resource provides two links to access its schemas:

  • blank schema which you can use as a blank content to create a resource
  • synopsis schema which is the same blank schema with additional details on each field

Let’s see what they look like for the address resource.

Blank schema

/api/adresses?schema=blank

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">

/api/adresses?schema=synopsis

<?xml version="1.0" encoding="UTF-8"?>

</prestashop>

JSON format

The Webservices can also output JSON instead of XML. To enable JSON output you have two choices:

Query parameter

Add one of the following parameters to your query string:

  • output_format=JSON
  • io_format=JSON

Example:

https://UCCLLQ9N2ARSHWCXLT74KUKSSK34BFKX@example.com/api/?output_format=JSON

HTTP header

Add the one of the following headers to your HTTP request:

  • Io-Format: JSON
  • Output-Format: JSON

Example:

GET /api/ HTTP/1.1
Host: example.com
Output-Format: JSON
Authorization: Basic UCCLLQ9N2ARSHWCXLT74KUKSSK34BFKX
