## Request

### Path parameters

### Body (application/json)

This endpoint expects a ConsentEvidence.

- `purposes` (list of enum, required) — Only the purposes the customer ticked.
  - Allowed values: `KYC_PAN`, `MF_HOLDINGS`, `PARTNER_SHARE`
- `granted` (boolean, required) — `false` relays a withdrawal.
- `captured_at` (datetime, required) — When the customer agreed. Not in the future; relayed within 24 hours.
- `ip` (string, required) — The customer's IP address when they agreed.
- `consent_text_version` (string, required) — The version of Liquify's consent text you showed. Wording you wrote yourself is refused.
- `device` (string, optional) — The customer's user agent or device.

## Response

### 200

The customer's consent per purpose, after this call.

- `data` (list of ConsentState, required)
- `meta` (Meta, required)

## Errors

### 400 Bad Request Error

`VALIDATION_FAILED` — the request breaks a rule in this spec.

- `type` (string, required) — `about:blank` — `code` carries the meaning.
- `title` (string, required)
- `status` (integer, required)
- `detail` (string, optional)
- `instance` (string, optional)
- `code` (string, optional)
- `errors` (list of string, optional) — One entry per field that failed validation.
- `request_id` (string, optional) — Quote it to Liquify support.
- `trace_id` (string, optional)

### 401 Unauthorized Error

`AUTH_INVALID_TOKEN` — no token, an unknown token, or your access is switched off.

- `type` (string, required) — `about:blank` — `code` carries the meaning.
- `title` (string, required)
- `status` (integer, required)
- `detail` (string, optional)
- `instance` (string, optional)
- `code` (string, optional)
- `errors` (list of string, optional) — One entry per field that failed validation.
- `request_id` (string, optional) — Quote it to Liquify support.
- `trace_id` (string, optional)

### 403 Forbidden Error

`ACCESS_DENIED` — this API is not switched on for you; `CONSENT_REQUIRED` — the customer has not granted (or withdrew) a purpose this call needs.

- `type` (string, required) — `about:blank` — `code` carries the meaning.
- `title` (string, required)
- `status` (integer, required)
- `detail` (string, optional)
- `instance` (string, optional)
- `code` (string, optional)
- `errors` (list of string, optional) — One entry per field that failed validation.
- `request_id` (string, optional) — Quote it to Liquify support.
- `trace_id` (string, optional)

### 404 Not Found Error

`NOT_FOUND` — not a customer on your book, or (create) an unknown verification.

- `type` (string, required) — `about:blank` — `code` carries the meaning.
- `title` (string, required)
- `status` (integer, required)
- `detail` (string, optional)
- `instance` (string, optional)
- `code` (string, optional)
- `errors` (list of string, optional) — One entry per field that failed validation.
- `request_id` (string, optional) — Quote it to Liquify support.
- `trace_id` (string, optional)

### 429 Too Many Requests Error

Rate limited. Liquify's limits answer a problem (`MF_SYNC_RATE_LIMITED` is the customer's sync cooldown); the edge's per-caller limit answers with NO body. Either way, wait `Retry-After` seconds.

- `type` (string, required) — `about:blank` — `code` carries the meaning.
- `title` (string, required)
- `status` (integer, required)
- `detail` (string, optional)
- `instance` (string, optional)
- `code` (string, optional)
- `errors` (list of string, optional) — One entry per field that failed validation.
- `request_id` (string, optional) — Quote it to Liquify support.
- `trace_id` (string, optional)

## Types

### ConsentState

- `purpose` (enum, required) — `KYC_PAN` — verify and use the PAN, name, DOB, gender and mobile to create the account. `MF_HOLDINGS` — fetch holdings from MF Central, CAMS or KFintech. `PARTNER_SHARE` — share the eligible amount, portfolio value and sync date with you.
  - Allowed values: `KYC_PAN`, `MF_HOLDINGS`, `PARTNER_SHARE`
- `granted` (boolean, required)
- `recorded_at` (datetime, optional, nullable)
- `consent_text_version` (string, optional, nullable)

### Meta

- `request_id` (string, required) — Ties a call to Liquify's records; quote it to support.
- `ts` (datetime, required)
