# One contact, with the supplier it belongs to

`GET /api/v1/contacts/{contact_id}`

## Request

- Base URL: `https://api.app.tightly.io`
- URL: `https://api.app.tightly.io/api/v1/contacts/{contact_id}`
- Auth: HTTP bearer

One contact: name, email, phone, city, country, description, role, department, preferred contact method, and the supplier it belongs to by id and name, with `is_primary_contact` saying whether it is that supplier's main contact.

`contact_id` is a whole number. A value that is not one is refused 400 before the database is touched, and one no contact has is refused 404.

A contact belongs to at most one supplier here: where a person is on several, this serves the first. `supplier_id` and `supplier_name` are null for a contact attached to no supplier.

Scope: `suppliers:read`.

## Path parameters

- `contact_id` string, required

## Headers

- `Tightly-Version` string

## Response `200`

The contact as it stands, with its supplier named.

## Other responses

- `400`: `contact_id` is not a whole number.
- `401`: No usable key: malformed, unknown, revoked, expired or stopped. One refusal covers all five, telling a caller which is which maps the surface for them. A request with no Authorization header at all is refused 400 before any key is looked for.
- `403`: The key may not reach this operation. `scope_missing` when the key does not hold Suppliers; `ip_not_allowed` when the caller's address is outside the key's allowlist. There is no `organization_mismatch` on this resource: no supplier or contact route names an organisation in its path, so there is nothing for a key to disagree with.
- `404`: No contact of this organisation has that id.
- `429`: The key has spent its allowance for this minute. 600 reads and 120 writes a minute, counted per key, refused calls included. `Retry-After` says how long to wait.
- `503`: The database is briefly out of reach, which is what a failover or a full connection pool looks like from outside. Wait the seconds `Retry-After` names and send the request again. A read is safe to repeat. A write is not, because the connection was lost in the middle of it, so read the object back before sending it a second time. Branch on the status rather than on `code`, which is `POSTGRES_UNAVAILABLE` from one of the two seams that raise this and `SERVICE_UNAVAILABLE` from the other.
