Hello EleanorS97809,
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.
Below I’m linking Optimize Press’s documentation on how to set up their 3rd party integration with Constant Contact.
Optimize Press Constant Contact Integration:
https://docs.optimizepress.com/article/2189-constant-contact-integration/
As this is a 3rd party integration which is not built or supported by Constant Contact, I would highly recommend reaching out to Optimize Press’s support team for any questions on how to configure the integration. Below I’m including a link to their support page.

Please note that Optimize Press 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,
