Create a repository dispatch event

Start the default branch's workflows that run on: repository_dispatch for event_type (those listing it under types, or with none). client_payload, a JSON object of at most 10 properties and 64 KB, is github.event.client_payload; github.event.action is event_type.

POST/repos/{owner}/{name}/dispatches

A workflow job’s own token may send one: with workflow_dispatch, it is how one workflow starts another. Needs the Write role (code:write). Returns how many runs started.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: workflow with action repository_dispatch, and the same inputs
Scope: An access token needs code:write.

Path parameters

Name	Type	Required	Description
`owner`	string	Yes	The workspace that owns the repository.
`name`	string	Yes	The repository’s name.

Body parameters

Send a JSON object. Names are snake_case, as in responses; the camelCase spelling is accepted too.

Errors

A failed request answers with one of these statuses and a body like {"error": {"code": "not_found", "message": "Repository not found."}}. See errors.

Status	Code	When
401	`unauthenticated`	A token is required, or the one sent is not valid.
403	`forbidden`	The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository.
404	`not_found`	It does not exist, or you cannot see it.
409	`conflict`	The request conflicts with the current state.
422	`invalid`	The input is not valid. `message` says which field and why.
