A customer contact can be linked to a vendor contact using this API. When you link two contacts together, you will get a unique VPA and virtual account number for that combination. In a marketplace solution, transaction happens between two parties. The virtual account/VPA generated can be used to uniquely identify collections happening between the two parties. The API also lets you specify the commission which you would like to take as a platform. Based on the commission set, the payout will get split between you and the vendor contact. Alternatively if you do not have dynamic commission structure between each combination, we can set a global commission which will be application to all the combination.
