Contactlist infusionsoft api

please look here but contactlist wher i get it please ?

In regards to your question, the Contact List contains an array of Contact Record ids.
They can be obtained from various places via the API, CSV, inputted data, etc.

If you open up a Contact Record within the Keap Application, you can see the “ID” Number in the Web Address, eg:

Hope that helps.
