Hi. I run the website for a fairly small company w/ about 35k contacts, split into about a dozen different lists (by physical location of the store the customer signs up at). They send all their newsletters manually. They have a web registration form for signing up new customers to their business. Within that form, there's a checkbox to opt in for newsletters. The website form onboards the customer, and if that box is checked, it makes a simple call through the v2 API (using the PHP SDK) to add the customer's email address to the list for the store they're signing up at. It's very, very simple. We don't store the customer's constant contact ID, but we do store the v2-style list ID for each store (integer). We have a single API key and access token. Are there any plans to build out a v3 PHP SDK? And/or what is the timeline on deprecation of the v2 contact endpoint? The company doesn't feel it's worth it to build and maintain their own miniature ConstantContact SDK to deal with OAuth tokens and all that just to simply add email addresses to one of a few static lists. It's not even clear that we would be able to do this in v3 in a simple way as the OAuth documentation is confusing and seems to imply the need for clients to login; and rewriting around this is unfortunately very low on the priority list for their own upgrade strategy. Will you continue to provide a simple endpoint where we can add email addresses to existing lists using just an API key?
