`campaigns.messageStructure`

Read what a campaign’s message is made of: every block, which ones ship verbatim, the instruction behind each generated one, the shape, and whether it is locked.


Endpoint	`POST /mcp/query`
Scope	`read`
Sandbox key	allowed
Extra entitlement	none
MCP tools	`selda_get_message_structure`
Convex function	`campaignBlueprints:messageStructureForApi`

A free sandbox key may call it.

Arguments

Argument	Type	Required	Notes
`campaignId`	`string`	required

What Selda fills in

You never send these. The HTTP layer overwrites them from the API key, which is what keeps one organisation’s data out of another’s reach.

Argument	Filled in from
`orgId`	your organisation, resolved from the API key

Example request

Required arguments only. Values in angle brackets are yours to fill in; the optional ones are in the table above.

curl -X POST https://api.selda.ai/mcp/query \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{ "fn": "campaigns.messageStructure", "args": { "campaignId": "<campaignId>" } }'

{
  "fn": "campaigns.messageStructure",
  "args": {
    "campaignId": "<campaignId>"
  }
}

Example response

Every endpoint answers in the same envelope.

{
  "value": <any | null>,
  "request_id": "req_..."
}

The function declares a return validator, so value is any | null.

On failure the body is { "error": { "type", "code", "message", "request_id" }, "request_id" } and request_id is echoed in the X-Request-Id header.

Generated from convex/lib/mcpRegistry.ts. Nothing in this reference sends: launchRun is in no registry and never will be, so a script can prepare a campaign completely and a person still presses send in the app.
