GitHub profile customization — what works via API vs manual

GH profile: API-patchable fields vs pinned repos

GitHub profile customization — what works via API

TL;DR

Field	API path	Token scope	Notes
bio	`PATCH /user`	`user`	Works. Up to 160 chars.
location	`PATCH /user`	`user`	Works. Trim trailing spaces or PATCH them off.
name	`PATCH /user`	`user`	Works.
company	`PATCH /user`	`user`	Works.
blog (website)	`PATCH /user`	`user`	Works.
twitter_username	`PATCH /user`	`user`	Works (despite the X rebrand the field name stays).
hireable	`PATCH /user`	`user`	Works. Boolean.
email	`PATCH /user`	`user`	Works (must be a verified email).
Pinned repositories	NONE	n/a	Not exposed by REST or GraphQL. Manual UI only.
Pinned gists	NONE	n/a	Same — manual only.
Profile README	Standard repo APIs on `<user>/<user>`	`repo`	Edit the README in `<user>/<user>` repo.
Avatar	`POST /user/avatar`	`user`	Documented but rate-limited.

Working PATCH example

val="$GH_ADMIN_PAT"
cat > /tmp/patch.json <<'EOF'
{
  "bio": "Software Engineering Specialist at TCS · building free public tools at @chirag127 · React Native + Astro + AI agents",
  "location": "India"
}
EOF
curl -X PATCH \
  -H "Authorization: Bearer $val" \
  -H "Accept: application/vnd.github+json" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/user \
  --data-binary @/tmp/patch.json

Quoting note: any non-ASCII characters (middle dot ·, em dash —, …) need a file-based payload + --data-binary. Inline -d strings with shell-quoting break on Windows Git Bash.

Why pinning doesn’t work via API

Investigated 2026-06-26 with full admin PAT (all scopes including user, repo, admin:org):

PATCH /user with pinned_items field → HTTP 200 but field silently ignored.
POST /users/<user>/pinned_items → HTTP 404 (endpoint doesn’t exist).
POST /user/pinned_items → HTTP 404.
GraphQL __schema introspection for Mutation fields containing “pin”: returns only pinIssue, pinEnvironment, pinIssueComment, unpinIssue, unpinIssueComment. No user-profile pin mutations.
The updateUserListsForItem mutation that DOES exist is for the Stars > custom lists feature, not profile pins.

Why GitHub keeps it manual: profile shape is meant to be a deliberate human action with the actual web UI as the only surface. Automating it would let token leakers reshape victim profiles silently — same threat model as profile-photo changes.

Manual pin flow (~30 seconds)

Go to https://github.com/<your-username> while signed in as yourself.
Click “Customize your pins” (top-right of the Pinned repositories section).
In the modal: uncheck currently-pinned items, check the desired 6 in order.
Click Save pins.

Verification after manual pin

gh api graphql -f query='{
  user(login: "chirag127") {
    pinnedItems(first: 6, types: REPOSITORY) {
      nodes { ... on Repository { nameWithOwner } }
    }
  }
}' --jq '.data.user.pinnedItems.nodes[].nameWithOwner'

Expected output: the 6 repo slugs in the order you checked them.

Anti-patterns tried + failed

PATCH /user with pinned_items array of node IDs → 200 OK but ignored.
Web-form scraping at https://github.com/<user>?tab=overview → CSRF-token + session-cookie protected; PAT auth doesn’t substitute.
DevTools MCP / Chrome session via this harness → opens a clean Chrome with no GitHub login; can’t reuse the user’s logged-in session.
gh auth refresh -s user followed by gh api PATCH → same result (works for bio, ignored for pins).

Recommended split

PATCH-able fields → automate in scripts, commit. Update bio whenever a major rebrand happens.
Pins → manual update ~once per quarter when the lineup shifts. Add a calendar reminder to review pins after every fleet scope change.
