I am developing a solution by using the Constant Contact API. Which uses the Bulk Activities Like (Adding Contacts, Clear Contacts and Export Contacts) excessively. I just want to know is there any restriction or throttling limit from Constant Contact for using on Bulk Activities per day?
There is, but the number is a very, very high one that you are highly unlikely to reach. It's not specifically on Bulk Activities but it is on the number of POST requests per second of our API. If you can provide some insight into what you're doing, we can give you some guidance on the volume and any potential ideas we have to help you.
Actually I am doing the excessive POST Requests. That are for creating lists may be (4 to 5 calls per day with 100+ lists), creating campaign and then creating contacts in bulk (5 to 6 calls or might be more per day with thousands of contacts might be 10,000+). Actually my client keep changing the contacts details that is why I need to POST all the contacts with all fields every time so the CC server update those contacts and also please let me know is that alright I mean.
I am not clearing the contacts from a list just POSTing them with latest details each time will the CC server automatically update them????
And also let me know is that OK with server to POST such a massive data repeatedly every time????
Certainly won't be an issue considering all you're doing is updating their contact details. It doesn't sound like you'd be doing more than 50-60 update requests throughout the day from your descriptiong, which won't be an issue at all.
