We would like to test additions and unsubcribes of contacts in a test mode, meaning not impacting the existing contact list. Is there anyway this can be done? How have other tested the implemenation of API for contact list management? Any help will be appreciated. Thanks.
We do not currently have any sandboxing features available for the API, so any changes that are made will affect the data in production. While this is something that we are looking into as a major value-add for our developers, there is another method that is available right now.
The Contact Management API functions are fully available to all Constant Contact accounts, including free trials. Thus, you could simply sign up a trial as a test account, which would allow you to test your code and how it works with contact data before working on the data in your live account.
If you have any questions, please let me know!
