Hello MarsiaP2,
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.
I wasn’t able to find any existing 3rd party integrations that were capable of connecting Eventeny with Constant Contact, nor do they appear to offer any public-facing API documentation, but if you are interested in developing your own integration between the two services I’d recommend contacting Eventeny Support directly to verify whether they allow developers to access their API:
Eventeny Support Options
https://www.eventeny.com/about/contact-us/
It would definitely be possible to add sign-ups from your event to your Constant Contact account using our V3 API. Below I’m including documentation for our sign-up form endpoint which will automatically check your account to see if the address you’re submitting already exists on your account and update the existing contact information if it does -or - create a new contact if it does not.
Create or Update a Contact:
https://developer.constantcontact.com/api_reference/index.html#!/Contacts/createOrUpdateContact
When developing your own application for integration, you’ll need to set it up so that the application calls/retrieves the data of your choosing using Eventeny’’s API (You will need to check their API documentation or contact their support team for help with how to configure this part), then you will program your application to sort out which variables you need and parse them into the correct format for Constant Contact’s API, at which point you can send that data through to the Constant Contact account via an authenticated connection (or vice versa).
Please note that Eventeny is a 3rd party product and not built or supported by Constant Contact, so we are limited in the support we can provide, but will try to answer any questions to the best of our ability as they pertain to Constant Contact’s API endpoints and functionality.
Please have a look and let us know if you have any other questions!
Regards,
