Synthesio
Add Synthesio to your product for your customers, and give your AI agents governed access to it.
Synthesio, now part of Ipsos, listens: it collects mentions of a brand from social networks, news, forums and reviews, classifies them for sentiment and language, and rolls them into metrics such as volume, share of voice and engagement. It does not publish, which is worth saying plainly because it changes what an integration is for. Your product reads, and what it reads is defined per customer, since each one builds their own dashboards, queries and listening taxonomy, so which topic or metadata field carries a product line or a campaign is their configuration rather than something you hard-code. Mention volume is the operational problem: a busy brand generates far more than one request returns, so reads are paged, paced and usually windowed by date. fastn holds each account's credentials and keeps the mapping per tenant.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own Synthesio account so the listening their insights team already runs feeds your product.
Read mentions with their sentiment and source, so your product acts on what was said rather than on a volume count.
Pull dashboard metrics such as share of voice and engagement, scoped to the queries that customer actually defined.
Map each customer's own topics and listening taxonomy, and window reads by date because a busy brand outruns a single page.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent explains why mention volume spiked for a brand and quotes the posts driving it.
An agent compares sentiment across sources for a period and reports where they diverge.
An agent tracks share of voice against a named competitor set, with every read logged per tenant.
Example prompt
Why did mentions of this brand spike last week, and was sentiment better or worse than the month before?
Set up Synthesio in 4 steps
- 01Enable the Synthesio connector in your fastn dashboard.
- 02Have each customer authorise their own Synthesio account so listening data is read under their credentials.
- 03Map the dashboards, queries, topics and metadata fields your product reads, and set the date windows you page through.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Synthesio integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Synthesio integration without building it. Your customers connect their own Synthesio account inside your product and work their records, datasets and fields there, with no per-customer code on your side.
- Handle the part that actually costs time: schemas differ per customer and change without notice, and volumes can be large. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Synthesio update is not your on-call problem.
- One integration serves your product and your agents. The same governed Synthesio connection powers in-product features and gives AI agents scoped, audited access, so you read and write your customers' data where it already lives without wiring it twice.

Hugging FaceSynthesio integration FAQ
How do I add a Synthesio integration to my product?
Enable the Synthesio connector in your fastn dashboard, then let each customer authenticate their own Synthesio account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Synthesio client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Synthesio account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Synthesio account and only ever sees their own records, datasets and fields. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Synthesio integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent explains why mention volume spiked for a brand and quotes the posts driving it.
Who maintains the Synthesio integration?
fastn does. When Synthesio changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Does the Synthesio integration adapt when a customer's schema changes?
Schema and field mapping is configuration per customer, so a change on their side is a mapping update rather than a code change and a release on yours.
How are large Synthesio reads handled?
Pagination and throttling are handled for you, and initial backfills are rate-limited so a large import does not exhaust a customer's API allowance.
What can I build with the Synthesio integration?
A common starting point: let each customer connect their own Synthesio account so the listening their insights team already runs feeds your product. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Synthesio integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Synthesio does not change your per-connector cost. You can start free with 3 connected accounts.
