## Deletes or cancels (5)

Removes, cancels or revokes something. Claude Code: deny.

### `referralrock_create_member`

- The name "referralrock_create_member" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: creates a new member (advocate) in a referral program and returns the member with their referral code and share URL. Not idempotent: a repeat call may create a duplicate or fail. When send_confirmation_email is true Referral Rock emails the member the program's confirmation email, which is a message to a real person; the default is false. POST /api/members.
```

### `referralrock_create_referral`

- The name "referralrock_create_referral" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: adds a referral (a lead) to the program of the member who owns the given referral code, as if the lead had used that member's link. A status of qualified or approved can trigger the program's configured rewards for the member, which is a financial commitment, so leave status out (new referrals start as pending) unless you mean it. Not idempotent. POST /api/referrals.
```

### `referralrock_record_customer`

- The description's first verb is "write": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: reports a paying customer to Referral Rock. A customer whose email matches a pending referral turns that referral to approved, which triggers the program's configured rewards for the referring member (a financial commitment that may be paid out automatically). A customer with no matching referral is added as a pre-loaded member to every program that has Preload New Customers on. Returns the outcome per customer (ReferralApproved, MemberPreloaded, Skipped…). Not idempotent. POST /api/customerfeed.
```

### `referralrock_update_member`

- The name "referralrock_update_member" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: changes contact details of an existing member, or disables / re-enables the member (a disabled member can no longer take part in the programs). Only the fields you pass are changed. The member is found by id, referral code, or email / external id plus program_id or program_name; Referral Rock updates it only when it is uniquely identified. POST /api/members/update.
```

### `referralrock_update_referral`

- The name "referralrock_update_referral" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: changes the status, amount or notes of an existing referral. Moving a referral to qualified or approved can trigger the program's configured rewards for the referring member (a financial commitment that may be paid out automatically), and denied stops them: confirm with the user first. Only the fields you pass are changed. The referral is found by id, or by external id / email plus program_id or program_name. POST /api/referral/update.
```
