When the Double the Donation team integrated our matching gift solution directly into the Blackbaud Raiser's Edge NXT donation form and confirmation page, we used the SKY Add-In model. We'd like to share how this integration method creates a deeply embedded contextual experience for our solution -- and lessons learned as the first Blackbaud partner to use this functionality. We will cover: - The nature of our solution along with how and why we used the SKY Add-In feature on the donation form and confirmation page - How we were able to handle the session state between donation form and confirmation page - How we worked with the SKY Add-In model given the nature of our tech stack, which is not .NET and Angular. We found that the SKY Add-In model is platform agnostic, and we will show how that impacted our integration build. We are looking forward to presenting our findings and answering any questions.
