Reviews
Post public replies to customer reviews (immediately or on a schedule).
Overview
Use the Reviews API when your integration responds to ratings on behalf of merchants. Replies can be sent now or scheduled for later.
What you can call
| Capability | Notes |
|---|---|
| Reply immediately | Returns the target service's opaque replyId after the provider accepts the reply and Otter records it |
| Schedule a reply | Pass an integer Unix timestamp in seconds as scheduledAt; success confirms scheduling only and does not return an eventual replyId |
Details: API reference.
Reply-size limits vary by serviceSlug and are measured in UTF-8 bytes. The
Public Reviews API does not expose reply editing, deletion, scheduled-reply
cancellation, or scheduled-operation status.
Current write-capable service limits are:
| Maximum UTF-8 bytes | Service slugs |
|---|---|
| 250 | grubhub, grubhubweb |
| 300 | coupangeats, deliveroo, deliveroo-web, doordash, doordash-api, ubereats, ubereats-api |
| 1000 | baemin, ddangyo-api, naver, yogiyo, yogiyo-api |
Confirm the configured limit during onboarding before treating it as a stable target-service contract.
