## Create a Lead

`POST /v1/leads`

Creates a patient inquiry or referral in the Organization. Attachments can use a public HTTPS URL or Base64-encoded data. Carebit validates and scans them for malware in the background; poll the returned remote file import batch for their status. Each successful request creates a new Lead unless the response is an Idempotency-Key replay. Carebit Pro is required.

**Required API scopes:** `leads.create`

## Parameters

- `Idempotency-Key` (header, `string`) (required) - Client-generated idempotency key. Required for every POST/PATCH write.

## Update a Lead

`PATCH /v1/leads/:id`

Updates any patient inquiry or referral in the Organization, regardless of how it was created. Use `stage_id` to move the Lead within the pipeline for its resulting `lead_type`.
