We're a junior developer team, creating an app for a Charity who uses Constant Contact.
Thanks to an answer on a seperate thread, we will be using the API & libraries we will be able to pull data & images from the library & have it populate in an App.
The only question that will prevent us from doing this now, is if there is any additional charge to a client's pricing plan? Will the client be charged extra for accessing the library through the API?
Thanks in advance!
