Input reference

Sends an SMS to a contact through the lemlist inbox. The message is sent to the contact’s phone number (phone field, or the first entry of phones). Sending consumes SMS credits, one per message segment.

Name	Type	Required	Default	Details
`payload.sendUserId`	`string`	Yes	—	Sender user ID. Must belong to the team owning the API key.
`payload.from`	`string`	Yes	—	Sender phone number, in E.164 format. Must be a phone number provisioned on your team; an unknown, pending or deleted number fails with `Failed to send SMS`.
`payload.contactId`	`string`	No	—	Contact ID. Provide either contactId or leadId (not both required). Returned in the response.
`payload.leadId`	`string`	No	—	Lead ID. Provide either contactId or leadId; when only leadId is sent, its contact is resolved and returned as contactId in the response.
`payload.message`	`string`	Yes	—	SMS body. lemlist variables such as {{firstName}} are resolved against the contact before sending, and the resolved message must not be empty.
