Documented steps Call POST https://api.github.com/repos/{owner}/{repo}/actions/variables with Authorization: Bearer <TOKEN> and Accept: application/vnd.github+json. Send a JSON body with name (required) and value (required), e.g. {"name": "BUILD_TARGET", "value": "prod"}. A 201 Created response confirms the variable was created; the response echoes name, value, created_at, updated_at. Variables are plaintext and visible to anyone with read access — never store secrets here. Reference in workflows via ${{ vars.BUILD_TARGET }}. Known gotchas Variable names are case-insensitive (stored uppercase per docs) and must match the allowed character/pattern rules; invalid names return 422. Unlike secrets, variables require no public-key encryption — submit the value as plaintext. Requires collaborator access on the repo for repo-level variables; org-level needs admin:org. Guidance: default variable names to UPPER_SNAKE_CASE and reuse across environments to keep ${{ vars.* }} references stable.
