How do I create custom field definition through Jentic?

The Twilio SendGrid Marketing Campaigns Custom Fields API exposes 4 endpoints covering custom fields operations.

Can I limit what my agent is allowed to do with the SendGrid Custom Fields API?

Yes. Because you run Jentic One yourself, your own rules decide which of the four operations the agent may call, so you can grant read-only access with GET /v3/marketing/field_definitions while withholding create, update, and delete. Since the custom field id sits in the URL path (/v3/marketing/field_definitions/{custom_field_id}), you can pin the agent to a single field definition, letting it update just that field and nothing else. Destructive calls such as DELETE /v3/marketing/field_definitions/{custom_field_id} stay off unless you explicitly add them, and the stored API key is injected at execution time rather than exposed to the agent.
