# Change a link

`PATCH /v1/projects/{project}/links/{smartLink}`

## Request

- Base URL: `https://api.subscriby.net`
- URL: `https://api.subscriby.net/v1/projects/{project}/links/{smartLink}`
- Auth: HTTP bearer

Any subset of the create shape; omitted fields keep their stored value. Renaming `slug` moves the web address and nothing else. `expires_at: null` clears an expiry. A `plan_id` is dropped when the destination stops being a plan. Emits `link.updated` with the fields that moved.

## Path parameters

- `project` string, uuid, required
- `smartLink` string, uuid, required

## Headers

- `Idempotency-Key` string, uuid, required

## Request body

- UpdateSmartLinkRequest: The changes to a Smart Link: any subset of the create shape. The code, and with it the bot link and the cookie, never change; renaming the slug moves the web address only.
  - `name` string: A new label, 2 to 120 characters.
  - `slug` string: A new address segment, 2 to 32 letters, digits and hyphens, lowercased before the uniqueness check against the project's other links; the old address stops answering.
  - `destination` 'portal' | 'plan' | 'bot': Where a Smart Link sends the person who follows it. The destination decides the redirect and the bot payload: the portal's plan list, the checkout of one plan, or a conversation with the project's bot. The click and the attribution are recorded the same way whichever it is, so a creator can move a link between destinations without losing its figures.
  - `plan_id` string, nullable: The plan a `plan` destination opens; one of this project's plans. Ignored when the destination is not, or stops being, a plan.
  - `expires_at` string, date-time, nullable: When the link stops counting, ISO 8601 and in the future, or null to run until archived.

## Response `200`

The link as it now reads.

- object
  - `data` SmartLinkResource, required: A Smart Link: a tracked address a creator hands out per channel (a video description, a bio, a flyer), with where it sends people, the three addresses to share and its lifetime clicks. Every member who signs in within the attribution window of clicking it is credited to the link.
    - `id` string, required: The link's id.
    - `project_id` string, required: The project the link belongs to; slugs are unique within a project, not across projects.
    - `name` string, required: A creator-facing label, never shown to visitors.
    - `slug` string, required: The address segment after `/go/`: 2 to 32 lowercase letters, digits and hyphens. Renaming it changes the web address; the code and the bot link stay.
    - `code` string, required: The stable seven-character code the bot link and the attribution cookie carry. Never changes, so a printed QR and a shared bot link keep working after a rename.
    - `destination` object, required: Where the link sends people.
      - `type` string, required: `portal` (the portal home), `plan` (the checkout of one plan) or `bot` (the project's bot, the portal home when no bot is connected).
      - `plan_id` string, nullable, required: The plan a `plan` destination opens; null otherwise.
      - `plan_name` string, nullable: That plan's name, present when the relation is loaded.
    - `urls` object: The addresses to share, each crediting this link.
      - `web` string, required: The `/go/` address on the portal host. Share it anywhere; a visitor is counted once per hour and remembered for the attribution window.
      - `bot` string, nullable, required: The project bot's deep link carrying `via_<code>`; null when the project runs no bot that hands out start links.
      - `embed` string, required: The plan-cards page to frame on the creator's own website, with the code in `via`; every card opens the portal in the top window through this link.
    - `state` 'expired' | 'live' | 'archived', required: `live` (counts and credits), `expired` (past `expires_at`: the address still lands on the portal home, nothing is counted) or `archived` (put out of use by the creator; the figures stay).
    - `expires_at` string, nullable, required: When the link stops counting, ISO 8601; null for never.
    - `archived_at` string, nullable, required: When the creator archived it, ISO 8601; null while in use.
    - `clicks` object, required: Lifetime clicks on the web address, one per visitor address per hour.
      - `total` integer, required: The count.
      - `last_at` string, nullable, required: When the address was last followed, ISO 8601; null when never.
    - `created_at` string, nullable, required: When the link was created, ISO 8601.
    - `updated_at` string, nullable, required: When it last changed, ISO 8601.

## Other responses

- `400`: `IDEMPOTENCY_KEY_MISSING`: every write needs an `Idempotency-Key` header. Send a fresh UUID per distinct operation.
- `401`: `AUTHENTICATION_REQUIRED`: the request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an `sbt_test_` token on production).
- `403`: `TOKEN_MISSING_ABILITY`: the token is valid but does not carry the ability this endpoint requires; `error.context.required_ability` names the one to grant. An endpoint that also checks who owns a row or which tier the account is on answers `FORBIDDEN`, `TEAM_TIER_REQUIRED` or `CONNECTOR_TIER_REQUIRED` with the same status, and says so in its own description.
- `404`: `RESOURCE_NOT_FOUND`: an id in the path names nothing the token can see. `TENANT_MISMATCH`: the project sits outside the token's `scope:project:` allow-list, or the token carries no team scope. Both answer 404 rather than 403 so that existence outside the token's scope cannot be inferred.
- `409`: `IDEMPOTENCY_KEY_REUSED`: the key was already used in the last 24 hours with a different request body.
- `422`: `VALIDATION_FAILED`: the payload broke a rule, and `error.fields` maps each offending key to its messages. A refusal from the domain, such as a plan that cannot go on sale or a member who cannot be removed, uses the same code with `error.message` saying why and no `fields`.
- `425`: `IDEMPOTENCY_REPLAY_IN_PROGRESS`: the first request with this key is still running; retry in a few seconds and the original response is replayed.
- `429`: `RATE_LIMITED`: the token has spent its 300 requests a minute or 10,000 an hour; `Retry-After` says when the next one is accepted.
