Review Management API
Pull reviews from Google Business Profile, Facebook, Trustpilot, and all major sources. Replies post straight to the source from your app, no second login required. Run sentiment, embed widgets, and trigger SMS or email campaigns. One REST API.
// Fetch recent reviews and post a reply
const headers = {
'Authorization': 'API your_api_key',
'Content-Type': 'application/json'
};
const locationId = 'TG9jYXRpb246MTI0MjE=';
// 1. Fetch recent reviews
const list = await fetch(
`https://api.synup.com/api/v4/locations/${locationId}/reviews?startDate=2026-04-01`,
{ headers }
).then(r => r.json());
const interactionId = list.data.interactions.edges[0].node.id;
// 2. Reply: interaction ID goes in the body
await fetch(
'https://api.synup.com/api/v4/locations/reviews/respond',
{
method: 'POST',
headers,
body: JSON.stringify({
interactionId,
responseContent: 'Thanks, Alex.'
})
}
);Aggregate reviews from Google, Facebook, Trustpilot, and all major sources
Synup aggregates reviews across the platforms that matter for local: Google Business Profile, Facebook, Trustpilot, and a long tail of industry-specific sources covering travel, healthcare, home services, automotive, and more. Reviews from any source come back through a single response payload with a normalized schema, so your code paths don't fork by platform.
Need a source we don't list? Add a custom interaction source through the API and reviews from that source flow through the same interactions schema.
Post review responses directly to Google Business Profile and Facebook
When a connected account is in place, POST /api/v4/locations/reviews/respond posts the reply directly to Google Business Profile or Facebook. The customer sees the response in the same place they left the review. No redirect, no second login, no "open Google to respond" friction in your UI.
"Click here to log into Google to respond."
Most agencies and SMB tools punt the user out of the product. Reply rates drop. Coverage breaks down at scale.
One API call. Response posts to the source.
Edits and archives also go through the API. Reply velocity stays high even when one operator is covering 200 locations.
Review Management API endpoints
Reviews show up in Synup as interactions. It's a unified type that covers reviews and ratings from every connected source.
Review Management API capabilities beyond aggregation
Aggregation is the baseline. Direct response posting, sentiment analytics, embeddable widgets, SMS or email campaigns, and custom source onboarding all run through the same API surface.
Direct response posting
Connected-account OAuth means responses post to Google or Facebook directly. Edit and archive flow through the same surface.
Sentiment and rollup analytics
Sentiment breakdowns, average rating, response rate, source mix, and time-series trends. The rollup endpoint pre-aggregates for fast dashboard queries.
Embeddable review widgets
Create a widget config, get a JS snippet, drop it on a customer's site. Sources, minimum rating, and styling are all configurable per widget.
SMS and email campaigns
Trigger review requests after a transaction. Reusable templates carry between campaigns, each one shipping to a branded landing page with its own delivery and performance metrics. Hand the platform a list and it handles the send window and follow-ups.
Custom review sources
Industry-specific platform you need to track? Add it through the interaction-source endpoint and reviews from that source flow through the same interactions schema.
Use cases for the Review Management API
CRM-triggered review requests
Order ships in Shopify, Synup fires a review campaign. Stripe payment succeeds, SMS goes out 48 hours later. Whatever the trigger, the request lands.
AI agents and MCP
Synup MCP lets Claude or GPT pull every client's reviews, draft responses in the brand's voice, flag reputation risks, and post replies through the same API.
Agency reputation desks
One operator covering hundreds of clients across every platform, in a single inbox. Reply, escalate, or archive through the API or the white-label dashboard built on top of it.
Embedded reputation features
SMB SaaS products that want to add “see your reviews” or “respond to reviews” without building 80 scrapers and OAuth flows.
Reporting and BI
Pipe interactions and interactions/analytics into BigQuery, Looker, or whatever the dashboard layer is. Sentiment over time, response SLA, source distribution.
