WMDA IT team creates applications for your organisation and provides the API Credentials (client_id and client_secret) needed to connect to WMDA APIs. Each application has a client_id (which is permanent) and requires client secrets to authenticate.
To authenticate with WMDA APIs, a bearer token must be requested from the WMDA. For details on how client_id and client_secret are used to retrieve bearer tokens and authenticate future requests to the WMDA API, see API authentication. |
Client_id
Client_secret
Client_id stays the same permanently. It does not expire and does not need to be replaced. Client_secrets expire after a set period. When the client_secret expires, API connections will stop working until a new secret is created and updated in your systems. To avoid interruptions, always rotate the secret before it expires. See 5. Email Notifications About Expiring Client Secrets below |
The Self Service API Credentials Portal lists the applications created by the WMDA IT team for your organisation. Each application represents access to one or more APIs.
Examples of applications you may see in the Self Service API Credentials Portal:
Partner-NL-OrganisationName-SMC
PartnerAlternative-NL-OrganisationName-SMC (sandbox only)
Applications naming convention follows this pattern: Partner-(Country Code)-(Organisation Name)-(API). Where:
Depending on the API permissions assigned to your application, it may have access to the following WMDA resources:
PartnerAlternative is a "dummy" organisation for implementers to test their Match-Connect API integration internally. It works only in the Match-Connect sandbox and is provided upon request. |
Each application has its own client_id and client secrets. Visibility depends on your user role (see 3. Access to the Portal below) and the API permissions assigned to your application.
You can manage client secrets using the Self Service API Credentials Portal, where you can view, create, and delete client secrets.

When you create a new secret, copy and store it securely. After you refresh or return to this page, the full secret will no longer be visible - only the first three characters (hint) will remain. If you don't copy the newly created secret, you lose it, and you'll need to generate a new secret. |
Once a new client secret is in use, the old one should be removed to prevent unnecessary expiration reminders and confusion.
