# Liquify Vendor API Reference

The **Liquify Vendor API** provides RESTful endpoints to facilitate loan-against-mutual-funds (LAMF) customer onboarding, identity verification, portfolio sync, and credit limit computation.

## Base URLs

All requests must be directed to your assigned Liquify gateway environment:

| Environment       | Base URL                       | Description                                         |
| :---------------- | :----------------------------- | :-------------------------------------------------- |
| **UAT / Sandbox** | `https://a7.liquifyfin-uat.in` | Partner staging and integration testing             |
| **Production**    | *(blank)*                      | Dedicated production endpoint provided upon go-live |

## Authentication

Every API call requires Bearer Token authentication via the `VendorBearerAuth` scheme. Pass your vendor token in the `Authorization` HTTP header:

```http
Authorization: Bearer <vendor_token>
```

> **Note**
>
> Each API is switched on for your organization individually. An API you do not hold returns `403 ACCESS_DENIED`. Keep your token confidential. If your token is compromised, contact Liquify Partner Operations immediately for key rotation.

## Request & Response Format

All API requests accepting a payload must send `Content-Type: application/json`.

* **Money** is formatted as a decimal string (e.g. `"245000.00"`), never a JSON number.
* **Timestamps** are ISO 8601 formatted strings.
* **Rate Limits & Failures** return a `Retry-After` header indicating seconds to wait.

### Standard Success Envelope (2xx)

Every successful response contains:

* `data`: The requested entity or operation payload.
* `meta`: Operational metadata including the unique request ID (`request_id`) and ISO 8601 timestamp (`ts`).

```json
{
  "data": {
    "customer_id": "cust_9830ed6a8ad3",
    "eligible_amount": "245000.00",
    "portfolio_value": "612500.40",
    "portfolio_synced_at": "2026-10-05T10:20:27Z",
    "stale": false
  },
  "meta": {
    "request_id": "38461348-c5e4-449c-b9cc-d6b08c06d11b",
    "ts": "2026-10-05T10:23:48Z"
  }
}
```

### Standard Error Envelope (RFC 9457 Problem Details)

All 4xx and 5xx errors adhere to RFC 9457 problem details (`application/problem+json`). The `code` field is from Liquify's stable error registry and never changes meaning:

```json
{
  "type": "about:blank",
  "title": "Forbidden",
  "status": 403,
  "detail": "Customer has not granted MF_HOLDINGS consent required for portfolio synchronization",
  "code": "CONSENT_REQUIRED",
  "errors": [],
  "request_id": "8b3b64dc-1123-4212-bf9a-3214819d4bca",
  "trace_id": "trace_796f5cdf"
}
```
