Add subscribers trough custom contact form and API

[KATHERINES18]

Hi, I have a static website that has a contact form. I use an API to process the contact info and then send it to my email. 
Every time a user submits this form, I would like to add it to my constant contact subscriber list.

Is that possible using Constant Contact API?

Hello Katherine,

Thank you for reaching out to Constant Contact's API Support.

Our API can do this; you'll want to take a look at our documentation which can be found at this website. https://developer.constantcontact.com/docs/developer-guides/overview-of-api-endpoints.html

Specifically if you are going to be integrating this with an existing form that uses an API you'll want to pay attention to the section on the right related to "Contacts." Ideally you will want to perform a GET on each contact submitted through your sign-up form to Constant Contact to see if the contact already exists. If it does not exist then you'll perform a POST; if it does exist then you'll perform a PUT.

Once you have gone over the documentation you are welcome to email us at webservices@constantcontact.com if you need further assistance.
