This operation bulk creates, or bulk updates, contacts in the import file.

Batch Calling Pattern

This method allows you submit data in bulk and works as part of the following calling pattern:

The method for polling for import job status is Get contact import status and the methods for getting the import job reports are Get contact import report and Get contact import report faults

🚧
Active contact imports are limited to 25
If you exceed this limit, you'll get the 'too many active imports' error.

File format

The import format can either be CSV or Excel. It must include one column called 'Email' (casing is not important). Any other columns will attempt to map to your custom contact data fields.

As shown in the code examples above, the server requires you to provide the filename parameter of the Content-Disposition header in the multipart body. Without this header, you'll receive the response { message: 'file must be valid' } with a HTTP 400 status code.

Passing consent

You'll need to specify the following additional column headers in your file in order to successfully import consent:

CONSENTTEXT
CONSENTURL
CONSENTDATETIME
CONSENTIP
CONSENTUSERAGENT

Passing Preferences

To pass marketing preference for a contact you must create a specifically formatted key value pair and pass it within the contacts dataFields array. The key is used to identify the preference to be set, and the value is a boolean (True or False). The key name should be formatted as follows:

Preference: {Preference name or category} > {Preference name}

Setting a top level preference

Preference:{Preference name}

Setting a preference in a category

Preference:{Category name}>{Preference name}

{
  "key": "Preference:MonthlyUpdates",
  "value": "False"
}

{
  "key": "Preference:Marketing>Offers",
  "value": "True"
}

File submission

You can call the method using either a JSON request (content-type: application/json) with the file data in base64 format, or by passing a file using a multipart form (content-type: multipart/form-data)

🚧
When using multipart form submissions
If using a multipart form submission to send the file, the server requires you to provide the filename parameter of the Content-Disposition header in the multipart body. Without this header, you'll receive the response { message: 'file must be valid' } with a HTTP 400 status code. e.g.
Content-Type: multipart/form-data;
Content-Disposition: form-data; name="contacts.csv"; filename="/C:/Example/contacts.csv"

Request Limits

There is a 50MB file upload limit; if your file is larger than this, please break your upload into separate files.
