# CreateImessageOptInLinkRequest
## Properties
**body** | **String** | Prefilled message text. Must contain the literal `[opt-in-code]` placeholder, e.g. \"Hi! My code is [opt-in-code]\". |
**parameters** | Option<**std::collections::HashMap<String, String>**> | Custom key/values (e.g. leadId, campaign) echoed back on the opt-in message. | [optional]
**opt_in_code** | Option<**String**> | Your own code in place of the generated one (3-8 characters, no spaces or `#`, `!`, `-`). An unredeemed link lives 24 hours; re-issuing with the same code replaces it, and the earlier URL stops matching. | [optional]
