upsertCarriers - Upsert carriers

<div class="extension-title">Description</div>

Use this API to share the channel's allowed list of carriers with Mirakl Connect, and keep it synchronized over time.

Important:

• You must provide the complete list of carriers in a single request, any carriers not included will be deleted
• If the marketplace allows it, you can add an "Other" carrier to cover unlisted carriers; otherwise, only include formally supported carriers
• We recommend sharing the full list of carriers: Mirakl Connect automatically maps carriers with slight naming differences
