This ID is created by allegro when you create a value in your allegro back-office.

Lengow will then match this value to the ID retrieved from your account via the allegro API, to send the corresponding allegro ID.

How to know if the matching has been done correctly?

If the value you've filled in in Lengow doesn't match with one of the value from your backoffice, the product will be in error. Please read the integration report and get back to the Attibutes Matching to change the value if necessary.
