For software platforms

Ship local marketing without building it

Your customers keep asking for listings, reviews and local SEO. Building that yourself means years of publisher integrations and a team to maintain them. Our API hands you the whole action layer, headless, under your brand.

Build vs buy

What you stop having to build

Everything here is something you would otherwise build and then maintain.

Ship in weeks, not years

The publisher network, the sync logic and the verification already exist and stay maintained.

Headless, so it is your product

Endpoints and webhooks only. Nothing surfaces our name to the people using your software.

A revenue line, not a cost line

Price local marketing into your existing plans at whatever margin your market supports.

Close the deals you were losing

"Do you handle listings?" stops being the question that ends the evaluation.

Multi-tenant already solved

Provision, meter and bill per customer account without building the plumbing yourself.

The agent, not just the data

Your customers get something that acts on their listings and reviews, not another set of read endpoints.

Scales past your roadmap

Millions of locations already move through the same endpoints you would be calling.

Compliance sits with us

GDPR, EU representation and access controls are handled on our side of the line.

MCP in both directions

Your assistant can reach into Synup, and the agent can reach out to the tools you already run.

Someone who knows platforms

A partner team that has done these integrations before, rather than a general support queue.

“Synup’s APIs made it incredibly easy to bring listings management directly into our platform. The integration is seamless, reliable, and backed by a highly knowledgeable team that understands our needs and is great to work with.”

Getting started

Three steps to a working integration

1

Take sandbox keys

Access the same day, with the full reference and a sample app you can read rather than guess at.

2

Map your accounts

One call provisions each of your customers under your account. We handle everything on the publisher side of it.

3

Expose what fits

Surface as much or as little as your product needs, priced and branded entirely as yours.

Questions

What platform teams ask first

Is it genuinely headless?

Yes. It is an API and a webhook stream. There is no embedded widget, no iframe and no Synup branding anywhere in the path. Your customers see your product.

How do we price this to our customers?

However you like. We bill you per location, you set your own retail price. Most platforms fold it into a higher tier rather than selling it as a line item.

Who owns the customer data?

Your customers do, and you hold the relationship. We process it to keep listings in sync and act as your processor under GDPR, with an EU representative in place.

How long does a first integration usually take?

Teams generally have something working against the sandbox in days and a production module in weeks. The long pole is your own product surface, not our endpoints.

Put it in front of your customers

Take sandbox keys and call the endpoints before you commit to anything. No contract to read first.
