Inputs

The fields this action accepts.

Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.

Field	Type	Required	Description
Owner owner	string	Required	GitHub repository owner — the user or organization login (the part before / in owner/repo URLs).
Repository repo	string	Required	GitHub repository name — the part after / in owner/repo URLs. Not the full URL.
Issue / PR Number issue_number	number	Required	GitHub issue number — the integer shown after # in the issue URL (per-repo, not global).
Labels labels	array	Required	Array of label names to apply to the issue. Each item must match an existing label on the repo exactly (case-sensitive). New labels are not auto-created.

Sample request

{
  "owner": "e.g. octocat",
  "repo": "e.g. hello-world",
  "issue_number": "e.g. 42",
  "labels": "[\"bug\", \"help wanted\"]"
}

Returns

[
  {
    "id": 1,
    "name": "bug",
    "color": "d73a4a"
  }
]

FAQ

Questions about Add Labels.

What does the Add Labels action do in GitHub?

Adds labels to a GitHub issue or pull request by name. Used for AI-driven triage or auto-tagging based on file paths touched.

What inputs does Add Labels require?

Required: Owner, Repository, Issue / PR Number, Labels. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if GitHub returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Add Labels support batch operations?

Yes. Run Add Labels inside a Loop node to process arrays. Tiny Command handles GitHub's rate limits automatically so you don't have to throttle manually.
