# Set a customer's auto top-up

PUT https://api.runledger.co/v1/customers/{customer_id}/auto_top_up
Content-Type: application/json

Buys credits for the customer when a pool's available balance falls to the `threshold`, up to `target_balance`, charging the payment method the customer saved at checkout. It replaces any auto top-up the customer has. The customer's plan must allow it (`top_up.auto.allowed`), the customer must have a saved payment method (otherwise `invalid_state`), and a `monthly_limit` above the plan's `maximum_monthly_limit` is `parameter_invalid`. The limit caps automatic purchases only, and a spend limit caps consumption. Setting a customer's auto top-up is a runtime write that takes `auto_top_up:write`. An agent key may turn it on within the plan's bounds or lower the limit, but not raise the limit in live. Credits it buys expire after the plan's `top_up.credits_expire_in`, or after one year when the plan sets none, the same as any other top-up. Creating the rule, changing it and turning it off (`status` `disabled`) each write an audit event with the actor: `auto_top_up.created`, `auto_top_up.updated` or `auto_top_up.turned_off`.

Reference: https://docs.runledger.co/api-reference/customers/auto-top-up/set

## Authentication

- `Authorization` header (bearer token, required) — A secret key (`rl_sk_test_...`, `rl_sk_live_...`) or a restricted key with limited scopes (`rl_rk_test_...`, `rl_rk_live_...`). A restricted key can carry `agent: true` and an `expires_at`, and is what a coding agent should hold. Keys end in a checksum so secret scanners can recognize them. People create, roll and revoke keys in the dashboard; `GET /v1/api_keys` lists them, masked.

## Request

### Path parameters

- `customer_id` (string, required) — The customer ID (`cus_...`).

### Body (application/json)

This endpoint expects a SetAutoTopUpRequest.

- `threshold` (string, required) — Buy credits when the pool's available balance is at or below this, as a decimal string.
- `target_balance` (string, required) — Buy enough to bring the available balance back to this. The purchase respects the plan's top-up minimum and maximum.
- `pool` (string, optional) — The pool to keep topped up. Defaults to the plan's `top_up.pool`.
- `enabled` (boolean, optional, default: true) — `false` buys nothing and keeps the threshold, so `balance.low` still goes out when the balance falls to it.
- `monthly_limit` (Money, optional) — The most automatic purchases may cost in a calendar month. It limits purchases, not consumption. If it blocks a purchase, Runledger buys what fits under the limit, if that meets the minimum.

## Response

### 200

The customer's auto top-up.

- `id` (string, required)
- `object` ("auto_top_up", required)
- `customer` (string, required)
- `credit_type` (string, required)
- `pool` (string, required)
- `enabled` (boolean, required)
- `threshold` (string, required)
- `target_balance` (string, required)
- `status` (enum, required) — `active` tops up. `disabled` stopped after three failures in a row, or because you turned it off. Set it again to re-enable.
  - Allowed values: `active`, `disabled`
- `consecutive_failures` (integer, required)
- `livemode` (boolean, required)
- `created_at` (datetime, required)
- `monthly_limit` (Money, optional) — An amount of money in the currency's minor unit.
- `purchased_this_month` (Money, optional) — What automatic purchases have cost since the start of the calendar month (UTC).
- `last_attempt` (AutoTopUpAttempt, optional)
- `actor` (Actor, optional) — Who last changed it.

## Errors

### 400 Bad Request Error

The request was malformed or a parameter was invalid. A configuration that fails validation, such as two equally specific overrides with overlapping dates, returns `config_invalid`.

- `type` (string, required) — A URI for the error type. It links to the error codes table in the docs, where each `code` is listed with its cause. Branch on `code`, not on `type`.
- `title` (string, required) — A short summary of the error type.
- `status` (integer, required) — The HTTP status code.
- `code` (enum, required) — A stable, machine-readable error code. New codes may be added.
  - Allowed values: `invalid_request`, `parameter_missing`, `parameter_invalid`, `parameter_unknown`, `authentication_failed`, `permission_denied`, `insufficient_scope`, `proposal_required`, `config_invalid`, `livemode_mismatch`, `resource_not_found`, `resource_already_exists`, `idempotency_key_in_use`, `idempotency_key_reused`, `invalid_state`, `outcome_charge_locked`, `hold_not_active`, `insufficient_balance`, `credit_limit_exceeded`, `plan_locked`, `test_clock_advancing`, `provider_error`, `rate_limited`, `api_error`, `service_unavailable`
- `request_id` (string, required) — The ID of the request. Quote it to support, or look it up in request logs.
- `retryable` (boolean, required) — Whether sending the same request again, with the same idempotency key, may succeed.
- `detail` (string, optional) — An explanation of this occurrence. For people; don't parse it.
- `param` (string, optional) — The request parameter at fault, as a dotted path.
- `required_scope` (string, optional) — The scope the call needed, on `insufficient_scope`. Ask a person to widen the key, or reconnect with it.
- `errors` (list of ConfigIssue, optional) — Only with `config_invalid`: each problem the configuration document has, with the path of the part at fault, so an agent can fix the document without a second call.
- `blocked_by` (list of ErrorResponseBlockedByItems, optional) — On an `invalid_state` that names the objects in the way, the objects that must change first. Removing a payment provider lists every routing rule that uses it (`object: routing_rule`) and every customer whose own `payment_provider` names it (`object: customer`), in one list.

## Types

### Money

An amount of money in the currency's minor unit.

- `amount` (integer, required) — Minor units. 1500 is US$15.00; 1500 is ¥1,500.
- `currency` (string, required) — Lowercase ISO 4217 code.

### AutoTopUpAttempt

- `status` (enum, required)
  - Allowed values: `pending`, `succeeded`, `failed`
- `at` (datetime, required)
- `credits` (string, optional)
- `payment` (string, optional) — The provider-neutral payment record (`pay_...`).
- `failure_code` (string, optional) — The provider's failure reason, as recorded on the payment.

### Actor

Who made a change. Runledger fills it in from the credential, so a client can't claim to be someone else: an API key always acts as itself, the dashboard calls the API as the signed-in person, and the MCP server passes the client's name and the person it acts for. A request that sends a `Runledger-Actor` header is refused with `400 parameter_unknown`.

- `type` (enum, required) — `user`: a signed-in person, including a person at Runledger support acting in your account, whose `name` reads `Runledger support`. `agent`: an agent connected through an OAuth session or an agent key. `key`: any other API key. `rule`: a reversal rule. `system`: Runledger itself, such as a clock.
  - Allowed values: `user`, `agent`, `key`, `rule`, `system`
- `id` (string, optional) — The user, key or agent session ID. Left out for `rule` and `system`, except a change a customer makes on the customer view, which carries the customer session's ID.
- `name` (string, optional) — A display name, such as a person's name, a key's name or the MCP client.
- `on_behalf_of` (string, optional) — The person an agent acts for, when known.
- `client` (string, optional) — The software that made the call, such as an MCP client or SDK.

### ConfigIssue

A problem or warning about a part of a configuration document.

- `code` (string, required) — A stable code. New codes may be added.
- `message` (string, required)
- `path` (string, optional) — Where in the document, as a dotted path.

### ErrorResponseBlockedByItems

- `object` (enum, required) — The kind of object in the way: a routing rule, or a customer with a `payment_provider` override.
  - Allowed values: `routing_rule`, `customer`
- `id` (string, required) — The object's ID, `rr_...` for a routing rule and `cus_...` for a customer.
