A clientId is a REST API login, it works in pair with a dedicated clientSecret.
For SOAP API credentials please go to your Seller Portal > Rights Management page.
Some connectors refer to "clientId/clientSecret" with "login/password" terms, REST APIs require either : only
the sellerId (through an agregator), or 3 information (clientId/clientSecret/sellerId).
If only 2 are requested then refer to SOAP Credentials.
Please make sure your agregator has registered with us before and is using the REST API.
For SOAP API login/password please refer to your Seller Portal > Rights Management page.
Using delegated REST, agregators request : a single sellerId.
Using SOAP, agregators request : a login/password pair.
Some agregators request a complete set of clientId/clientSecret and sellerId.
Works for direct connection plugins only, which expect 3 parameters : clientId, clientSecret and SellerId.
For third party issued plugins use "Agregator connexion" (above).
Migration from SOAP to REST APIs is still ongoing, some plugin providers might not have already provided an updated plugin.
Older plugins only require a login and a password.
Rest compatible plugins require clientId/clientSecret/SellerId.
Using the REST API requires a clientId/clientSecret pair, and a link with your SellerAccount.
SOAP API credentials are still managed from your SellerPortal.
You might just need a clientId and do not want to link it to a seller account ?
Start by creating an account, stop after retrieving credentials.
