Add unique Coupon to email in AJO

[montezh2001]

Hello, 

I have a client that has 100K unique (1x use only) Coupon Codes to 100K profiles. We only want to append 1 unique coupon code  to a profile. No 1 coupon code should exist across more than 1 profile; it should be a 1:1 append. 

How can I accomplish this in AJO since they don't have a Coupon Management component? 

Please advise

Couple of options - 

If you have a REST API service which can return a coupon code for every request made, the same can be configured in custom actions and custom action response can then be used in emails for personalization https://experienceleague.adobe.com/en/docs/journey-optimizer/using/configuration/configure-journeys/... 

Other way is to have a csv file containing the mapping of coupons to profiles and using custom upload audiences for targeting and personalization https://experienceleague.adobe.com/en/docs/journey-optimizer/using/audiences-profiles-identities/aud...
