For the most up-to-date information on the Contacts API, please visit the new Marketing Campaigns Contacts API.
The Contacts Recipients API allows you to manage your recipients. You can add, retrieve, update, and delete recipients, as well as get a count of all recipients and all billable recipients.
This endpoint allows you to add a Marketing Campaigns recipient.
You can add custom field data as a parameter on this endpoint. We have provided an example using some of the default custom fields SendGrid provides.
The rate limit is three requests every 2 seconds. You can upload 1000 contacts per request. So the maximum upload rate is 1500 recipients per second.
Bearer <<YOUR_API_KEY_HERE>>The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
