Rate Limit


Rate Limit

Hello dear,

I need to understand about rate limit API

In API Guide say that I can use API key to send up to 10,000 requests per day and 4 requests per second,

so what do you mean by request ?

Is request mean that I can Send API Request what ever emails include inside it?

or just I can send 10,000 email per day?


Thank you




Thank you for reaching out to Constant Contact API Developer Support.


This rate limit applies only to the number of calls you can make to the API and is not related to any limits within the account itself. So you can take actions with the API such as adding contacts (individual or bulk), and can do that and other actions 4 times per second up to 10,000 times per day.


Please let us know if you have any other questions!
