Create a segment

Create a segment

Creates a segment of the contacts that match an SQL-style query, optionally within one list, that updates as contacts change.

Note: Counts refresh every 1 to 24 hours, and a segment built on engagement data takes about 30 minutes to start filling.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://api.sendgrid.com
• Endpoint: POST /v3/marketing/segments/2.0
• Auth: send the header Authorization: Bearer $SENDGRID_API_KEY
• Get a key: https://app.sendgrid.com/settings/api_keys
• Docs: https://www.twilio.com/docs/sendgrid/api-reference

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
