## Request body

- object — Optional overrides used when preparing the Solana subscriptions create-plan transaction.
  - `destinations` string[] — Allowed destination addresses for the on-chain plan. Defaults to the stored plan destination.
  - `pullers` string[] — Allowed puller addresses for the on-chain plan. Defaults to the stored puller or owner address.
  - `endTs` string — Optional unsigned 64-bit Unix timestamp when the on-chain plan ends.
