# Standing instruction — on demand

> On-demand SI — register a mandate on PayDirect initiate when PayGlocal has enabled on-demand SI on your MID.

<span className="payments-v2-page hidden" aria-hidden="true" />

## On-demand standing instructions

**On-demand SI** is a **PayGlocal MID configuration** — not a restriction that `standingInstruction.data.frequency` must be `ONDEMAND`. You can set any supported `frequency` in the request body.

Use this flow when on-demand SI is enabled for your account. Registration uses the same PayDirect initiate endpoint as [GPI](/api-reference/payments-v2/paydirect/gpi) with a `standingInstruction` block.

### Key points

* Register the mandate using the **Initiate API** with `standingInstruction.data` (see **Request body**).
* **`frequency`** (`ONDEMAND`, `WEEKLY`, `MONTHLY`, etc.) is a mandate field only — PayGlocal does **not** auto-debit on that schedule for on-demand SI. You trigger **every** subsequent debit by calling the **[SI sale API](/api-reference/standing-instructions/si-subsequent-payment)** (billing cadence is up to you).
* Subsequent debit amounts:
  * **`FIXED`** — same `amount` each time.
  * **`VARIABLE`** — up to `maxAmount` per debit.
* **`mandateId`** is returned in the Initiate API response (`data.mandateId`) and must be stored for future mandate operations. It is **not returned again** in later transactions.

## Supported payment methods

| Method | Domestic | International |
| ------ | :------: | :-----------: |
| Cards  |     —    |       ✓       |

Standing instructions support **international cards** only. In **Request body** → `paymentData`, send **`cardData` only** (`tokenData` is not supported). UPI, net banking, and domestic-only methods are not supported.
