FAQ

Frequently asked questions

01

How do I securely obtain an API V3 access key from Constant Contact?

To obtain your credentials, access the Constant Contact Developer Portal securely. Log in and go to 'My Applications', then create a new application to generate your API keys and access tokens safely for integration usage.

02

Can the AI mistakenly delete entire segmented contact lists indiscriminately?
