Sumsub — Manage Applicant Tags

Adds, replaces, and removes tags on an applicant profile, always followed by a read-back. Tags are free-form labels used for filtering and classification in the applicant list; they are also readable as applicant.tags in workflow routing and TM rule expressions.

Endpoints

All writes return {"ok": 1} on success. Tag names not seen before are auto-created on both the add and the overwrite endpoint (sandbox-verified; the docs' claim that overwrite requires pre-existing tags is outdated).

Tag definitions — renaming a tag, picking its color, or the "include tag in applicant summary report" flag — are Sumsub dashboard UI only (Applicant tags page); there is no public-API surface for them.

Auth — App Token + secret (sandbox only)

This skill talks to the public Sumsub API and signs each request per the authentication reference. The full how-it-works writeup lives in the [sumsub-api-auth](../sumsub-api-auth/SKILL.md) skill — read it if you hit 401 Invalid signature.

⚠️ Sandbox tokens only. Do not accept or use a production App Token
here. If the user offers one, refuse and ask them to generate a sandbox
pair at <https://cockpit.sumsub.com/checkus/home?sbx=true>; (**Connect
Sumsub to your AI agent -> Build & configure -> Generate token**).
Token + secret are shown once — copy both before closing the dialog. The helper script
enforces this — it rejects tokens that don't start with sbx:.

If the user has already supplied credentials in conversation, reuse them; otherwise ask once before running. Never echo the secret back.

Procedure

1. Pick the operation. Default to the additive add — it is safe and

deduped. Use overwrite only when the user explicitly wants to replace the whole set (or clear it); use remove to take specific tags off. Do not pre-GET before add or remove — the endpoints are targeted and idempotent, the read-back in step 3 is the verification.

1. Overwrite only — confirm first. GET the applicant, show the user the

current tags that will be lost, and get explicit confirmation before POSTing the replacement set. Same gate applies to clearing all tags (overwrite with []).

1. Run the write via the orchestrator (it appends the read-back

automatically):

``bash bash scripts/manageapplicanttags.sh list <applicantId> bash scripts/manageapplicanttags.sh add <applicantId> "High Risk" "VIP" bash scripts/manageapplicanttags.sh overwrite <applicantId> "Compliance Reviewed" # after the confirm step! bash scripts/manageapplicanttags.sh remove <applicantId> "Legacy KYC" ``

1. Compare the read-back to what was requested. An empty set comes back

with the tags field absent from GET /one — that is the normal "no tags" state, not an error. On a mismatch, report it — do not retry automatically. Surface 4xx errors verbatim.

1. Report, names first. Lead with the applicant's name and the resulting

tag list, then the dashboard link (https://cockpit.sumsub.com/checkus/applicant/<applicantId> — render as a clickable markdown link), and put the applicant id on its own last line.

Gotchas

• 30-tag cap per applicant. Exceeding it (existing + new) fails the whole

request with HTTP 400 "Too many applicant tags" — atomically, nothing is applied. Report the 30-tag limit and stop there: do not trim the list and retry, and never delete or overwrite existing tags to make room in the same run — freeing up slots is a destructive decision the user must make explicitly, in a fresh request.

• Tag names are case-sensitive — "High Risk" and "high risk" are two

different tags. Match the user's existing casing when removing.

• Overwrite replaces everything. POST .../tags with any body wipes tags

not listed in it. When the user says "add", never use the overwrite endpoint.

• Empty = absent. After clearing tags, GET /one has no tags field at

all. Read-back logic must treat a missing field as an empty set.

• Unknown applicant → HTTP 404 "Applicant with id ... not found (anf)"

(not 400). Ask the user to re-check the id.

• Tag changes fire the applicantTagsChanged webhook — relevant if the

tenant subscribes to it (see sumsub-manage-webhooks).
