Contacts are people saved in Apollo.

Use the Create a Contact endpoint to add a new contact to your team's Apollo account.

By default, Apollo doesn't apply deduplication processes when you create a new contact via API. If your entry has the same name, email address, or other details as an existing contact, Apollo creates a new contact instead of updating the existing contact. To enable deduplication and prevent duplicate contacts, set the run_dedupe parameter to true.

To update an existing contact, use the Update a Contact endpoint instead.

typed_custom_fields

object

Add information to custom fields in Apollo.

Your custom fields are unique to your team's Apollo account. This means that the examples in this documentation may not work for your testing purposes.

To utilize this parameter successfully, call the Get a List of All Custom Fields endpoint and identify the id value for the custom field, as well as the appropriate data type. For example, if a custom field accepts picklist entries, you need to pass the accompanying id value for the picklist entry that you want to use as the input value.

Example: When the Get a List of All Custom Fields endpoint returns an id of field:

"60c39ed82bd02f01154c470a" (datetime)

then the value passed should be:

{"60c39ed82bd02f01154c470a": "2025-08-07"}

run_dedupe

boolean

Defaults to false

Set to true to enable deduplication logic that prevents creating duplicate contacts. When enabled, Apollo will check for existing contacts with matching email addresses, names, or other identifying information and return the existing contact instead of creating a duplicate. The default value is false.

When deduplication is enabled, performance may be slightly impacted due to the additional validation checks, but this ensures data integrity and prevents duplicate entries in your database.
