Send one customer a review request by email, text, or both, using a campaign's templates. An email in the body uses the Email channel and a phone the SMS channel; each channel needs an attached template. If only one channel is usable, only that one is sent (200); 400 only when none is usable. Counts against the plan's email and SMS allowances (402 when used up).

Prerequisites: a bearer token, and a campaign in your account with an enabled channel that has a template, on a location with an active plan.

Authentication: Account token. The campaign must belong to your own account; otherwise 403.

Rate limit: 60 requests per minute, counted per user (the token’s user).
