Getting List of Campaign Options



One of the options for getting a list of email campaigns is below. Can you give more explanation of this 'modified_since'? Does it mean that a campaign can be changed and then resent?  Thanks   (also, how to you mark a post 'answered' on this forum?





Retrieve only contacts modified since the time specified (in ISO-8601 format)

Re: Getting List of Campaign Options

Hi Mike,


The modified_since parameter for campaigns refers to the most recent change(such as a change in their status or contents). After a campaign has been sent, the only reason this could change is if you were to trigger a re-send of the campaign. Additionally, it is not possible to edit the contents of a campaign once it has been sent.


You can read about resending campaigns here:, and you can read about resending in the API here:


For the last question, there should be a button that is visible to the original poster of a thread below each reply that is labeled "Accept as Solution".


If you have any questions, please let us know!
