Hi there, we're using Square for processing payments for our SaaS business. I would like to know how we can create a promo code for subscription? I can see how this is done for Items but not Subscriptions. We are using the Square API. Is there any way we can do this through Squarre's Developer portal?
Hi @NewSaaSBusiness,
Right now, promotions can't be applied to subscription links, but you can create a free trial period when creating a subscription plan. Here's what this looks like:

While I'm not sure if this is something you could get around using API, our developer forum would be the best place to get expert advice.
PS. I noticed it's your first post, welcome to our community 👋
