Move Your Setup
by Script, Zone by Zone

Your Kevel setup exports as JSON, so the rebuild can be scripted. The real work is replacing your Decision API calls — scope that first.

Export and rebuild

~1–2 weeks

Step 1 A day

Export from the Management API

Your full setup, including targeting, as JSON.

Step 2 About a week

Rebuild in Epom via API

Map campaigns, zones and priorities to Epom objects. Script it, or use the MCP assistant.

Integration

~1–2 weeks

Step 3 A few days

Decide your serving model

Tags or server-side via the ad API. Tags are faster.

Step 4 1–2 weeks

Rebuild the serving integration

Swap Decision API calls for Epom tags or ad API calls.

Switch

Per zone

Step 5 A few days

Link, map and validate

Link banners, carry targeting over, test on a live page.

Step 6 Per zone

Parallel-run, then cut over

Run both, reconcile, then switch zone by zone.

What your engineer needs to scope first Data move, serving integration, server-side serving, gaps and reporting history
The data move
Straightforward. Kevel’s Management API exposes advertisers, campaigns, flights, ads, sites, zones, ad-types, priorities and targeting as JSON, and Epom’s API creates the same objects, so the transfer can be scripted end to end.
The serving integration
This is the project. Your application currently calls Kevel’s Decision API server-side; on Epom you either move to tag-based serving or wire the serving API in its place.
Server-side serving
Works through the ad API and Direct URL, passing the end user’s IP and user agent so targeting, capping and fraud checks stay per user. An OpenRTB endpoint runs the full serving path.
What does not carry over
Epom does not rank products from a catalog for sponsored listings.
Reporting history
It does not transfer — pull it through the Reporting API before you close the account.

The Questions That Come Up on Every Call

01

Which verticals does Epom accept?

Adult, gambling, crypto, dating and nutra all run. The platform sets no vertical restrictions; creative moderation is yours to switch on.

02

Do I have to stay headless?

No. Most teams move to tags and drop the integration. If you need to stay server-side, Epom serves through its ad API or Direct URL, with the end user’s IP and user agent passed through. Sponsored-listing ranking from a product catalog is the one thing it does not do.

03

Can I keep working API-first?

Yes. The whole platform is API-driven — you can build your own advertiser interface on top of it and let your clients log in to something you designed. The difference is that you do not have to. A full UI ships with it, so a non-engineer can run campaigns from day one.

04

What does Kevel do that Epom doesn’t?

It is purpose-built for retail media — catalog ingestion, sponsored listings, auctions you control, and ML forecasting. It also lets you bring your own relevance model. Epom has none of those.

05

What does Epom cost?

$250 a month at 8.5M display and mobile web impressions, rising by volume. Every add-on is priced on the pricing page.

06

Can I resell inventory to third-party advertisers?

Yes. Sub-accounts with granular permissions let each advertiser and publisher log in to a platform carrying your brand.

07

What happens to my reporting history?

Pull it through Kevel’s Reporting API before you close the account. Epom does not import it.
