Open a draft version

POST /api/v1/sequences/{sequenceId}/versions Opens a draft as a copy of the published version — nodes, contents, wires and trigger included. Answers 201. The trigger is copied as it is: a draft opened this way runs on the trigger of the version it copies, until you change it with Change a draft's trigger.

Condition	Answer
no draft open	`201` — you get a new draft to edit
a draft is already open	`400` — one draft at a time; publish it or discard it

Authorization

Role in the organization	This endpoint
`OWNER`	Allowed
`ADMIN`	Allowed
`MEMBER`	Refused — `403`

A key carries the role its creator holds in this organization — never a role on AgentsMail itself. See API keys.

Path parameters

Parameter	Type	Description
`sequenceId`	string	Required. The sequence to open a draft on

Example

bash

curl -X POST -H "x-api-key: $AGENTMAIL_API_KEY" \
  "https://www.agentsmail.io/api/v1/sequences/$SEQUENCE_ID/versions"

Response

201 Created — the created resource.
401 Unauthorized — missing or invalid key, or its owner left the organization.
403 Forbidden — the key's owner is a member of the organization, not an admin.
404 Not Found — no such resource, or it belongs to another organization. The API never confirms that an id exists to a caller who has no right to it.
429 Too Many Requests — over 120 requests in a minute for this key.
