# Function: normalizeMessagesIfNecessary()

> **normalizeMessagesIfNecessary**(`messages`): [`MessageGenerated`](https://docs.bitbadges.io/sdk/reference/interfaces/message-generated)\<`AnyMessage`\>[]

Defined in: [packages/bitbadgesjs-sdk/src/transactions/messages/utils.ts:29](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/transactions/messages/utils.ts#L29)

Normalizes messages by ensuring they have the proper structure.
Because the current and other code doesn't support Msgs with optional / empty fields,
we need to populate undefined fields with empty default values.

## Parameters

## Returns

[`MessageGenerated`](https://docs.bitbadges.io/sdk/reference/interfaces/message-generated)\<`AnyMessage`\>[]
