Notes

Permanent Deletion: This action cannot be undone. The lead will be permanently deleted.
Need the lead data? The delete response only confirms deletion—it doesn’t return the lead’s details. If you need the lead information (metadata, status, etc.), fetch the lead first using GET /api/v1/leads, then delete it.
URL Encoding: When passing phone numbers in the URL, remember to URL-encode the + sign as %2B.
Access Control: You can only delete leads that belong to campaigns your API key has access to.
