How Long Does Offerwall Integration Actually Take? (Plus AI Prompts for Your Coding Agent)

Someone has asked you to scope an offerwall integration, and every vendor page you have opened says the same three words: quick and easy. None of them say what quick means in hours, which is the only number you actually need in order to answer the question you were asked.

So here are the numbers for RevU and for the rest of the market, what drives them, where integrations genuinely go wrong, and two sets of prompts you can paste straight into Cursor, Claude Code, or whatever agent you are using: one wired to RevU, one generic enough for any offerwall.

The short answer

• RevU web-based integration: under an hour of engineering. It is a URL you open and a server endpoint that receives a completion. There is no SDK, no dependency, and nothing added to your build.

• RevU API integration: roughly one to two days. Only needed if the offer list has to render inside your own UI. You are writing a client against three documented APIs plus the same postback handler.

• SDK-based networks: measured in release cycles and sometimes months, not hours. The code you write may be small. The dependency resolution, device QA, store review, staged rollout and version fragmentation around it are not, and they repeat on every SDK update.

The important distinction is not the first number. It is that one of these is a one-time cost and the other is a recurring obligation on a codebase you have to keep shipping.

Why the honest answer has two numbers

Engineering time and elapsed time are different, and vendors quote whichever is more flattering.

Engineering time is how long a developer spends writing and testing code. For RevU's web-based path that is genuinely under an hour, and most of it goes on the postback handler rather than on the offerwall itself.

Elapsed time is how long until you are live, and it includes things that have nothing to do with code: creating a publisher account, agreeing terms, getting the placement approved, and your own release process if the entry point ships inside an app binary. Elapsed time is usually a few days, and almost none of that is engineering.

We will give both, because scoping a ticket with the first number and then missing the date because of the second is how these projects get a bad reputation internally.

RevU web-based integration, step by step

The whole integration is two moving parts: a link that opens the offerwall, and an endpoint that hears about completions.

1. Create the placement and get your Offerwall ID. In the Publisher Portal, open the Offerwall tab, create a placement, and note the Wall ID. Portal work, a few minutes, and no code.

2. Add the entry point. The offerwall is a URL in the form https://wall.revenueuniverse.com/[Offerwall ID]/offers/[User ID]. You add a button that opens it with your Wall ID and your own identifier for the signed-in user. Ten to fifteen minutes.

3. Write the postback handler. RevU calls your server when a user completes an offer, and your server credits the reward. This is the real work in the integration, and it is where the twenty to thirty minutes goes.

4. Configure and test the postback. Set your endpoint in the Publisher Portal and fire test postbacks from the portal's testing interface before you send real traffic. Ten minutes.

That is the integration. There is no SDK to add, no dependency to resolve, no build size change, and no permissions to justify in review.

One honest caveat: if the button ships inside a native app binary, adding it still requires a release, because you are changing your app. The difference is that this is a single release, once. After that, offers, catalogue changes and platform updates all propagate server-side without you shipping anything. Teams that gate the button behind remote config avoid even that first release.

When you need the API integration instead

You need it when the offer list has to render inside your own interface rather than RevU's hosted page. That is the only real reason. If a hosted offerwall is acceptable, take the web-based path, because it is materially less work and there is nothing to maintain.

The API path means writing a client against three documented endpoints, each of which has both a technical document and a Swagger specification:

• Get Offers returns the offer catalogue.

• Get Progress returns a user's status against offers they have started.

• Get Personalized returns a ranked, per-user offer list.

Authentication uses Wall API Keys and an Account API Key from the Publisher Portal, and the calls belong on your server rather than in a client. You still need the same postback handler, so the API path is the web-based work plus a UI plus a client. One to two days is realistic for a developer who has the docs open, and the Swagger specs make it faster than that estimate suggests if you generate the client.

Why SDK-based integrations take longer

This is structural rather than a comment on anyone's engineering. Adding a third-party SDK to a mobile app means:

• Dependency resolution. The SDK pulls transitive dependencies that may conflict with what is already in your build. This is the step that unpredictably costs a day.

• Build impact. Size, permissions, and anything you now have to explain in a privacy disclosure.

• QA across your device and OS matrix, because the SDK now runs inside your process and can affect things that have nothing to do with the offerwall.

• Store review, which is a queue you do not control.

• Staged rollout, then waiting to see whether crash rates move.

• Version fragmentation afterward, because users who never update are running an old SDK indefinitely.

Then every SDK update repeats most of that list. This is the actual argument, and it is why comparing integrations on initial hours alone misses the point. A no-SDK integration is a fixed cost. An SDK is a subscription paid in engineering attention, and the invoice arrives at every release.

Where this is unflattering to RevU: SDKs buy you things a URL cannot. Native rendering that matches your app exactly, offline behavior, deep lifecycle hooks, and in-process analytics are all easier with an SDK in the build. If those matter more to you than the maintenance cost, that is a legitimate trade and you should make it deliberately.

How long does each offerwall take to integrate?

Integration time is decided by integration method, not by brand, and there are only three methods across the whole offerwall market. They sort cleanly by effort.

• Hosted or web offerwall, no SDK. You open a URL or an iframe and receive completions on a server-to-server postback. Nothing enters your build. Fastest tier: hours to about a day of engineering.

• REST API. You call the network's endpoints and render the offers in your own UI, still crediting through a server-side postback. Roughly one to two days, because it is the web-based work plus a client and a UI.

• Mobile SDK. A native library compiled into your app. The code you write can be small, but dependency resolution, device and OS QA, store review and staged rollout are not, and they repeat on every SDK update.

Where each network lands is set by its own published integration docs, and several offer more than one path. The big-name incumbents are mostly SDK-first. adjoe's Playtime is a native SDK with no no-SDK option. Tapjoy, ironSource Offerwall and Unity LevelPlay have all been folded into one product, Unity Grow Offerwall, whose documented placements are native SDK code. A newer group, including AdGem, ayeT-Studios, BitLabs, CPX Research, Revlum and OfferToro, integrates through a URL or iframe with a server-to-server postback and no SDK at all. Digital Turbine's Fyber Offer Wall straddles the line: SDK-first by default, but with a documented Offer Wall REST API that skips the SDK.

Figures are engineering time for a first integration, keyed to the method rather than to a promised vendor number. Elapsed time to going live depends on your own account setup and release process. Networks with more than one path are shown by their lightest documented option, so the comparison is fastest-path against fastest-path.

What the table does show is where the effort concentrates. The offerwalls like Unity are the ones that put a native library in your build and bill you again in QA and re-release at every SDK update. RevU's minimum viable integration has no SDK at all: a URL your users open and a postback your server answers, under an hour of engineering, with an API path available when offers need to render in your own UI. That is the whole reason it sits at the top of the table. A network whose only path is an SDK cannot offer a sub-hour integration, and the recurring cost, not the first afternoon, is what a timeline comparison is really measuring.

What you need before you start

Almost all of the delay in a "slow" integration is missing prerequisites rather than difficult code. Have these ready:

• A Publisher Portal account and an Offerwall ID.

• A server endpoint that can receive an HTTP GET and reach your rewards system. Postbacks are server-to-server. There is no secure client-side alternative.

• A stable, unique, resolvable user identifier.

• A decision on your currency conversion ratio, anchored to your in-app purchase pricing. This is a business decision, not an engineering one, and it is frequently the thing actually holding up launch. We covered how to set it separately.

• Somewhere to test that is not production.

Where offerwall integrations actually go wrong

In rough order of frequency:

• Guessed macro names. Postback macros are documented, and they differ between networks. Copying a macro name from a previous integration produces a handler that silently receives nothing useful. Read the docs and use the names in them.

• Non-idempotent handlers. Postbacks retry. If your handler credits on every call rather than keying on the transaction identifier, you will double-credit, and you will find out from your economy rather than your logs.

• Ignoring status. A postback carries a status field. Not every one is a completion, and reversals exist. Handlers that credit unconditionally are a fraud surface.

• Unresolvable user IDs. Covered above, and it is the one that generates the worst support experience, because the user genuinely did the work.

• WebView rendering. Offers that redirect out fail inside an embedded browser, which looks like poor conversion rather than a broken container.

• Going live without testing postbacks. The Publisher Portal has a testing interface. Every problem above is cheaper to find there.

RevU's preflight checklist is built to be run against a finished integration before you send traffic.

AI prompts for integrating RevU

These are written to be pasted into an AI coding agent. The design principle throughout is that the agent should read the documentation rather than recall an API from training data, because parameter and macro names are exactly the thing models confabulate most confidently. If you are integrating a different offerwall, skip to the generic versions in the next section.

Generic AI prompts for any offerwall

The prompts above are wired to RevU's docs. These are the same jobs written to be provider-agnostic, so they work for any offerwall you choose. Replace [PROVIDER] with your network's name and [PROVIDER DOCS URL] with the root of its developer documentation, then paste. The single rule that makes AI integration reliable for any offerwall is the one carried through all of them: the agent reads your provider's own docs rather than recalling an API from training data, because parameter names, postback macros and endpoint shapes are exactly what models confabulate most confidently.

1. Project rules file (any offerwall)

Save as AGENTS.md, CLAUDE.md, or your agent's equivalent.

# Offerwall integration: rules for AI coding assistants
# Provider: [PROVIDER]   Docs: [PROVIDER DOCS URL]

## Read first, always
Before writing any code, fetch and read the provider's own integration docs at
[PROVIDER DOCS URL]. Do not rely on memory for parameter names, postback macros,
endpoint paths or field names. If a name is not in the docs, stop and ask.

## Ask before writing any code
1. Which surface is the reward on? iOS, Android, Unity, web, or desktop.
2. Do we have a server that can receive the completion callback and reach our
   rewards or currency ledger? Reward crediting is server-side and not optional.
3. Which integration path does [PROVIDER] offer, and which fits us:
   - a hosted or web offerwall opened by URL or iframe, with no SDK
   - a REST API where we render the offers in our own UI
   - a mobile SDK with native rendering
   Prefer the lightest path the design allows. A no-SDK path adds nothing to the
   build and needs no re-certification when we ship.
4. Do we have a publisher account and a placement or app ID from [PROVIDER]?

If the answer to 2 is no, stop and say so.

## The user identifier
Whatever identifier we pass is returned on the completion callback and is how we
know who to credit. It must be stable across sessions, unique per user, and
resolvable in our own database later. Never use a session token or a resettable
device ID as the sole identifier.

## Postbacks / completion callbacks (required)
- Server-to-server request from [PROVIDER] when a user completes an offer.
- Use the exact macro or parameter names from [PROVIDER DOCS URL]

Then separately confirm:
- No API keys or placement IDs are committed to the repository.
- The callback handler is idempotent and handles reversals rather than crediting
  unconditionally.
- If this is a web offerwall, it opens in an external browser on every platform
  we support.

If you are still scoping

The question behind the question is usually whether this will block a release, and for the web-based path the answer is no, because nothing goes into your build. If you want a second opinion on which path fits before you commit engineering time, our team will look at it, and the publisher page covers what the integration gets you once it is live. If you are earlier than that and still deciding whether an offerwall belongs in your product at all, our guide to cash versus virtual currency rewards is the better starting point.

RevU is a rewarded advertising and offerwall platform connecting advertisers with mobile publishers. Founded on 20 years of adtech operating history, RevU is the longest continuously-operating offerwall in the gaming ecosystem and integrates without an SDK via iframe, hosted page, or whitelabel API.
