ISO Help! Selling gift cards on store front vs. selling gift certificates in Scheduling

My client has her website for clients to primarily book appointments with her. She also occasionally sells a few products on her online store. She wants to add a gift card to her online store so clients could redeem it for either booking an appointment through Acuity Scheduling or purchasing a product. Is there a way to add a gift card that could apply to both?

From what I understand, if you sell gift cards through your online store – you can only redeem gift cards for products on your online store. If you sell gift certificates through Acuity Scheduling, can you only redeem gift certificates for booking appointments? Is there a way to integrate both?

I have the same question. How can my customer sell gift cards at her store front and online. I already have three gift card options set up in Acuity, but she uses Square as her POS in-store. I have Square integrated with her Squarespace Acuity, but how do we allow clients to sell gift cards in their store and have it provide a code that is recognized and accepted by Acuity?
