# Prepare subscription plan creation

Prepares an unsigned Solana subscriptions program create-plan transaction from an SDP subscription plan.

`POST /v1/payments/subscription-plans/{planId}/prepare-create`

This derives and stores the plan PDA but does not submit the transaction.

Requires an [API key](/docs/developing-with-sdp/authentication) with the `recurring.manage` action.

## Headers

- **`x-project-id`** · `string` · min length 1 · example `prj_example`

  Required for dashboard sessions. API keys use their assigned project.

## Request body

`application/json`

Optional overrides used when preparing the Solana subscriptions create-plan transaction.

- **`destinations`** · `string[]` · max items 4

  Allowed destination addresses for the on-chain plan. Defaults to the stored plan destination.

- **`pullers`** · `string[]` · max items 4

  Allowed puller addresses for the on-chain plan. Defaults to the stored puller or owner address.

- **`endTs`** · `string` · pattern `^\d+$` · example `1770000000`
