Input reference

Sends the draft from the inbox address. A reply draft is sent in its thread. A draft without a thread starts a new thread. The draft must have at least one to recipient and html or text, or the request returns a 422. A standalone draft also needs a non-empty subject. A reply draft with an empty subject is sent with the thread subject, prefixed with Re: when it does not already start with it. A draft that was already sent returns a 409. The request body is optional and takes only headers. The whole email, encoded, can be at most 40 MB, or the request returns a 422.

Name	Type	Required	Default	Details
`payload.inbox_id`	`string`	Yes	—	The Inbox ID or the inbox email address, such as `support@acme.com`. A value that contains `@` must be a valid email address, and any other value must be a UUID, or the request returns a 422. The address match is case-insensitive and never falls back to the inbox `name`. An address that matches no inbox returns a 404.
`payload.draft_id`	`string`	Yes	—	The Draft ID. Format: `uuid`.
`payload.headers`	`record`	No	—	Custom headers to add to the email. The `In-Reply-To`, `References` and `Reply-To` headers are set by Resend and cannot be set here. Sending one of them, in any letter case, returns a 422. Header names cannot be empty, and names and values cannot contain line breaks or null characters, or the request returns a 422. `null` means no custom headers.
`payload.idempotency_key`	`string`	No	—	Stable send identity for retries. Resend deduplicates for 24 hours. Plays derive a step key when omitted. Minimum length: 1. Maximum length: 256.

Output reference

Standard tool result payload.

Name	Type	Required	Default	Details
`result.data`	`object`	Yes	—	Provider response payload.
`result.data.id`	`string`	Yes	—	The ID of the sent email. Use it with the emails endpoints. Format: `uuid`.
`result.meta`	`object`	No	—	Additional response metadata (status, paging).
