# Update a contact

`PATCH /api/v1/contacts/{id}`

## Request

- Base URL: `https://app.blueticked.com`
- URL: `https://app.blueticked.com/api/v1/contacts/{id}`
- Auth: HTTP bearer

Partially update a contact's profile, tags, or suppressed flag.

Send only the fields you want to change, and at least one field: an empty body answers 400 validation_failed. Changing or clearing phone/email clears consent for the old identifier.

Set a matching *_consent field to true to record fresh permission for the effective identifier. Email consent still follows the business's double opt-in policy.

## Path parameters

- `id` string, required

## Request body

- object
  - `business_id` string, uuid, nullable
  - `phone` string, nullable: Phone in international form (+27821234567) or South African national form (082 123 4567); spaces and dashes are ignored. A number without a leading + or 00 is read as South African, so write a foreign number with its +. Stored and returned as E.164.
  - `email` string, nullable
  - `first_name` string, nullable
  - `last_name` string, nullable
  - `tags` string[]
  - `custom_fields` object
  - `suppressed` boolean
  - `whatsapp_consent` true
  - `sms_consent` true
  - `email_consent` true
