Use the Create Call Records endpoint to log calls in Apollo that were made using outside systems such as Orum or Nooks. This endpoint can only be used create call records, not to dial prospects.
This endpoint requires a master API key. If you attempt to call the endpoint without a master key, you will receive a 403 response. Refer to Create API Keys to learn how to create a master API key.
