Imports a collection of contacts. Creates contacts if they do not exist and updates contacts if they do. This is an async operation and you will need to check when it is complete by calling getImportStatus
Note: It isn't possible to specify the value for the contactId field when creating a contact, so it is only used to check for a matching contact when specified
Import limits
Your JSON request body can be a maximum size of 50MB, therefore allowing a large number of contacts to be imported in a single call.
Active contact imports are limited to 25. If you exceed this limit, you get the
Too many active imports
error.
Specifying
null
for a fields value clears the fieldYou must ensure that you only pass the fields you require to be updated for a contact.
We interpret a field passed with a
null
value as an instruction to clear the value for that field.
