The Partner ID is the unique identifier for the ATS.
The Customer ID is a unique identifier for a user within an Applicant Tracking System (ATS) that is using VONQ's services. This ID must be included with each API call to the Payment endpoints, as it is essential for VONQ to identify which user the payment is associated with and to whom an invoice should be sent. To find your Customer ID, you would typically look within the ATS you are using, as it is the unique identifier of the user in that system. When you need to create a Wallet with VONQ, for instance, you will provide your Customer ID to the /wallet POST endpoint, which implies that the ATS or the interface where you manage your VONQ services should allow you to access or create your Customer ID.
Both of these must be included with each API call utilizing the Payment endpoints, as VONQ needs to know for which ATS and which User the payment is associated with. Without this information, VONQ would not be able to identify to whom an invoice should be sent to, or whom a payment is coming from.
