Path: Queues API

`POST /v1/organizations/{orgId}/projects/{projectId}/queues/{queueId}/messages`

One request commits all its messages, or none: any invalid message refuses the whole request with an issue per field (messages.<i>.<field>). On a FIFO queue a message whose dedupId was sent in the last 5 minutes isn't stored again: it answers the original messageId with duplicate: true. 429 storage_limit_exceeded when the project's stored bytes are at their limit (2 GiB by default). Not recorded in Trails unless refused.

## Authentication

Requires one of the following:

- `apiKey`, http, header `Authorization`
- `oauth`, http, header `Authorization`
- `sessionCookie`, apiKey, in cookie

## Path parameters

- `SendMessages.path.orgId` (string, required)
  - format `uuid`
- `SendMessages.path.projectId` (string, required)
  - format `uuid`
- `SendMessages.path.queueId` (string, required)
  - format `uuid`

## Header parameters

- `SendMessages.header.Idempotency-Key` (string, optional) — Makes a retry safe: the same key and request get the stored response.
  - pattern `^[\x21-\x7e]{1,200}$`

## Request body

_Required._

- `SendMessages.messages` (array<object>, required)
  - `SendMessages.messages.body` (string, required) — UTF-8 text. The body and attributes together are at most 262,144 bytes.
  - `SendMessages.messages.attributes` (map<string>, optional) — At most 10. Keys match ^[A-Za-z0-9_.-]{1,64}$ and don't start with ezgh. (reserved for the ones Queues adds, such as ezgh.sourceQueue on a dead-lettered message); values are at most 1,024 bytes.
  - `SendMessages.messages.dedupId` (string, optional) — FIFO only, and required unless the queue has contentBasedDedup: a send with a dedupId seen on the queue in the last 5 minutes isn't stored again.
    - pattern `^[A-Za-z0-9_.:-]{1,128}$`
  - `SendMessages.messages.delaySeconds` (integer, optional) — Standard queues only: this message's delay, in place of the queue's.
    - min 0; max 900
  - `SendMessages.messages.groupId` (string, optional) — Required on FIFO queues, refused on standard queues.
    - pattern `^[A-Za-z0-9_.:-]{1,128}$`

## Example request

  "messages": [
    {
