Create or update contacts

Create or update contacts

Queues up to 30,000 contacts, or 6 MB, to be created or updated in Marketing Campaigns and returns a job ID.

Note: Asynchronous: a 202 means queued, and the job_id shows the import status. To update a contact, send all of its existing identifiers. Create custom fields before you set them.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://api.sendgrid.com
• Endpoint: PUT /v3/marketing/contacts
• 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.
