Getting access with API Client credentials

To access the API, you need Client credentials. On this page, you will find more information about Client credentials and how to create them. Some of our gold, silver and bronze partners are connected to our simplified authentication process. You can read more about how the authentication process works with these third-party partners at the bottom of this page.

Client credentials allow you to authenticate to the Retailer API. Client credentials are a kind of username and password for the API. Below are the steps to create client credentials:

1. Log into the sales account, open the settings page and go to 'API Instellingen’ under the 'Instellingen' heading.

2. Fill in the contact details of your technical contact and click 'Opslaan'.

These contact details are used to inform you of important updates and news surrounding the API. Therefore, be sure to fill in the contact details of the person who is technically responsible for your API connection.

3. Below the header 'Client credentials for the Retailer API', click 'Aanmaken'.

In the text field, enter a name for the credentials. Preferably use a name from your internal or external software. If you use a third party for the API (an integration partner, fulfilment party for example), enter the name of this party. After filling in the name, click ‘Aanmaken’.

4. The Client credentials are now created.

The Client ID is automatically displayed in the screen. When you click ‘Toon secret’, a pop-up containing the Client secret opens.

5. When using an integration partner/third party, enter Client credentials in their system.

If you want to connect with multiple third parties, you need to create separate Client credentials for each party. When you stop working with a third party, you can also easily delete their Client credentials.

Here you can also see when the authorisation expires. The authorisation is valid for one year, after that, you have to authorize again. Fortunately, most authorised parties send a notification before the expiry date to remind you of this.

4. Do you stop using the third party at some point?

You can remove it in your sales account, below the heading ‘Authorised parties for the Retailer API’.
