Hello JenniferC8130 ,
Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.
After taking a look online, I wasn’t able to find any pre-built third party integrations between Toast and Constant Contact. You may want to also check with Toast to see if they have any feature like this, in case it exists but is not listed in a public facing resource.
If you are unable to find a 3rd party integration that meets your needs, Constant Contact provides developers with free access to our API endpoints so that you can build your own application for integration. However, it looks like, while Toast does offer API access, the documentation is not public facing, and their API access is only available to those with active accounts and partner status approval.

Constant Contact V3 API Documentation

When programming/building your own integration, you’d set it up to call the data of your choosing in Toast using their API, have your program sort out which variables you need, and then use Constant Contact’s API to send that data through to the desired list (or vice versa).
Please have a look and let us know if you have any other questions!
