Error Code 5, also known as Developer Error, is a common problem developers encounter during in-app purchase or subscription integration on Google Play. This error occurs when there are discrepancies in API parameters or if the app’s configuration is not properly set in the Google Play Console. It can prevent developers from completing critical in-app billing integrations, but following a few focused troubleshooting steps will help resolve the issue.
Error Code 5 generally happens when the app doesn’t pass the expected parameters correctly in API calls or is misconfigured in the Google Play Console. For instance, developers may attempt to send incomplete or incorrect purchase or subscription IDs, or the product IDs might not match those configured in the Play Console. Additionally, this error can arise if the app is not properly linked to the billing configuration in the Play Console, causing the Play Store to reject the request.
This error commonly occurs in the following situations:
Error Code 5 - Developer Error is typically due to incorrect parameters or configuration issues in Google Play’s billing setup. By verifying product IDs, reviewing API parameters, publishing to a test track, and ensuring proper Play Console configuration, developers can resolve this error efficiently.

Learn how to craft compelling paywalls that convert users and drive sustainable revenue for your app. Discover app growth strategies like A/B testing paywalls, personalization in apps, and more.
Millions of apps clamor for a user’s attention.
Let’s consider the area of fitness. There is a smorgasbord of options, catering to every exercise whim. You've got the high-octane training apps that turn your phone into a pocket-sized drill sergeant, the zen yoga and meditation apps that help you find inner peace, and the gamified fitness companions that make getting fit feel like playing your favorite video game. From couch potato to gym rat, there's a fitness app out there for everyone.
This is just one example of the diversity of apps. Dive deeper and you'll find a universe of apps dedicated to sports, games, news, entertainment, productivity, creativity – the list goes on!
With so much competition, how do you make sure your app survives and thrives?
In-app purchases are the lifeblood of any app's success. Whether you're an app marketing guru or an app product owner, you need to constantly innovate and keep users feeling like they're getting their money's worth.
Just look at the numbers: consumers shelled out a whopping $171 billion across app stores in 2023. That's a lot of spending! And it doesn't stop there – the app economy itself is a behemoth, valued at a staggering $1.7 trillion, with US companies leading the charge.
So, how do you tap into this goldmine?
Enter the paywall: a strategic tool that lets you offer premium features or content within your app, but with a twist – users gotta pay to play. Paywalls have the potential to unlock a treasure trove of revenue and propel your app's growth.
But here's the catch – they can also be a double-edged sword. A poorly designed paywall can be as frustrating as a bad hair day, affecting user retention.
The key is to optimize app paywalls. By crafting user-centric paywalls that clearly communicate value and make subscribing a breeze, you can transform that dreaded "wall" into a gateway to a world of exciting content, activities, and adventures.
This article is your roadmap to mastering paywall optimization. We'll talk about why you need to be thinking strategically about paywalls, best practices for app paywall design, and deep-dive into app growth strategies to maximize paywall conversion rates and drive revenue.

Here’s how a well-designed paywall can determine not just how users engage with your app, but also the impact on your business goals.
Imagine this: instead of just casual users, you have a legion of loyal fans. That's the power of a good paywall. By clearly showing the value of premium features, you entice users to invest in your app. This translates to them sticking around longer, being a part of a community that feels like a VIP club and ultimately driving app monetization.
A clunky paywall is the app equivalent of stepping in gum – frustrating and sticky. Optimization ensures a smooth experience by presenting the paywall at the right moment in a user’s journey, with clear and concise messaging. It's like a maître d' who guides you to the best seat in the house. This keeps users happy and more likely to see the value of upgrading, reducing churn, and keeping those frustration headaches at bay.
There's no one-size-fits-all paywall. Here's a quick rundown of popular models to pick a paywall that works for your users:
Before you can start reaping the benefits of in-app purchases you need to optimize your paywall. Here's a step-by-step guide on how to optimize a paywall for a mobile app that unlocks sustainable app growth.
Knowing what your app users want (and when they want it) is critical for the success of your app. Make use of surveys, focus groups, customer interviews, and even in-app analytics to uncover their needs, pain points, and the features they crave the most.
Your paywall shouldn't be a cryptic riddle. It needs to scream the value users unlock by upgrading. Forget dry feature lists – translate them into user benefits! Don't say "unlimited storage," say "Never get that dreaded 'storage full' message again!" Focus on user retention by solving user pain points and making their app experience epic.
A/B testing lets you experiment with different paywall elements and assess what prompts users to take action toward paid or premium plans. Here are some elements you can test –
Discover insights from A/B testing paywalls for mobile apps.
Imagine a treasure map that leads directly to a user's heart's desire. That's the power of personalization in apps. Use user data to tailor paywall offers and messaging to individual users. For example, a fitness app user who religiously uses workout playlists can be shown a paywall highlighting ad-free music. This targeted approach makes the paywall more relevant and impactful, significantly boosting paywall conversion rates.
Ensure a clear and concise layout with easy-to-understand pricing and a smooth payment process. Minimize clicks and unnecessary steps. Remember, a smooth journey makes users more likely to reach the final destination – becoming a paying, happy app user.

The experiment: Streaming giant Spotify tested the waters back in September 2023 with a new paywall feature – hiding song lyrics behind a premium subscription. A select group of users encountered a pop-up message urging them to upgrade to "Spotify Premium" in order to “enjoy lyrics."
The goal: Spotify likely wanted to achieve two key objectives through this A/B test:
The outcome: As Spotify themselves acknowledge, this is an ongoing A/B test. They haven't revealed the timeframe or specific results yet. However, the data gathered from user behavior during this test will be crucial in determining the future of lyrics access on the platform. Will it remain freely available, or could it become a premium perk? Only time (and the A/B test results) will tell.
Key takeaways:

Paywall AB testing is an essential strategy for any app publisher wanting to optimize revenue.
Paywall AB testing is a necessary strategy for any app publisher wanting to optimize revenue. In this article we’ll provide an introduction to paywall testing by covering the following topics:
The paywall screen is how apps make money through IAPs and subscriptions. In fact, most app publishers spend very little time updating their paywall let alone optimizing it.
The paywall can be one of the essential elements contributing to your success in growth and retention this year. Let’s take look:
Focusing on app growth usually means a combination of efforts including:
It’s important that new users see your paywall during their first session. In fact, 70-80% of subscription starts occur on the day of install (D0) according to data from AppsFlyer and Redbox Mobile.
Considering this, it’s important to think of your paywall as not one monolithic object that all users flow through regardless of origin. That would be like having a single landing page on your web site regardless of traffic source.
Conceptually, you want different paywall instances aligned to each acquisition source:
To optimize in-app revenue, your paywall needs to be operated like a growth marketing asset, not a static coded screen.

Most app publishers use push notifications for app engagement. Push can be a helpful way to improve D7 retention, but you should also consider what happens once the user is in the app.
It may not be obvious, but the paywall isn’t just important for growth. It’s important for retention as well especially for subscription apps. Consider that most app subscriptions are auto-renewable. The desired state for app publishers is for a user to be a paying subscriber on an annual plan with auto-renew turned on.
However, subscription customers can end up in other states as well. The paywall can help you message users in context of those other states to nudge them to that desired place.
Here are a few example of retention paywall instances tied to user context:
The key to effective retention paywalls is to power your experience with individual-level subscriber data. This means your external marketing channels, the in-app experience, and everything in-between should all have the same context about a user’s subscription journey. This way, the experience including marketing assets will be personalized and relevant.
Yes, you should be conducting paywall AB testing. The exception to the rule is if your app doesn’t have much usage. If this is you, focus on top-of-the-funnel activities such as ASO keyword tuning.
If you do have steady app traffic, you almost certainly will be able to improve in-app revenue via one or more of the following:
If your app has only one paywall, you can benefit from paywall AB testing. Most apps convert at low enough rates that much upside exists. Here are a few guidelines:
Sadly, it’s not uncommon to see freemium app with free-to-paid conversion rates of less than 1%. With testing, you can boost conversion to 5-15% or more.
For apps with a hard paywall, conversion rates depend on whether you offer a free trial or not. It’s not uncommon to see trial conversions of 5% or more. With testing, you can boost free trial conversion rates to 30-50% or more.
No matter what your conversion rate is, your paywall can be improved. The only question is by how much.
Just realize that the one-size-fits-all paywall won’t be perfectly aligned with each and every user. For fully optimized revenue, you’ll need to move to multiple, segmented paywalls.
As we’ve explained, to optimize in-app revenue it’s important to have different paywalls focused on different acquisition channels and user context. To say this another way, you should have a paywall segmentation strategy.
With paywall segmentation, you and an opportunity to conduct paywall AB testing that is focused on improving the specific metric that a certain paywall is responsible for.
For instance, you could run a test of the paywall presented to users acquired via Apple Search Ads to tightly focus on improvement to that channel. For instance, you could focus on improving your ROAS (Return on Advertiser Spend - defined as the total revenue generated divided by total ad spend).
Similarly, you can test variants of your Annual Offer to see which does a better job of converting existing monthly subs to your annual plan.
To prioritize your testing strategy, focus on the key metrics you’re trying to improve first. Also look for the opportunities that have a lot of room for improvement so you can get some quick wins.
If you’re convinced your app is a good candidate for paywall AB testing, let’s take a look at how you actually run a test. We’ll cover the three key elements to help you get started with your first test:
There are different tools and techniques for running an AB test. For the purpose of this article, which pertains to mobile app paywall AB testing, you have the following options:
There are pros and cons to each of these approaches. If you’re already using a general purpose tool, something like Optimizely might make sense. The downside, is it’s not particularly mobile-first and certainly wasn’t built to focus on testing paywalls.
A solution like Firebase is closer to mobile-first, but is not as friendly for the marketing folks on your team that are used to great campaign management systems.
In our humble opinion, Nami is the easiest way to ship a mobile paywall and yes, conduct paywall AB tests. In fact, no code is needed to design the paywall or run the test. Our powerful campaign engine helps you with paywall segmentation so can focus the right test on the right outcome.
Now that you’ve chosen a tool, it’s time to figure out what you want to test. As we’ve discussed you may have multiple paywalls each playing a different role in your growth and retention strategy.
This means the elements you will want to test really depends on the paywall and it’s purpose. Here are just a few things you might test based upon common mobile app paywall designs:
Remember, the element you want to change needs to align with the metric you want to influence. For example, if you want to drive more users into choosing the annual plan the possible elements to test may narrow to:
Your test can include multiple changes to the paywall or a single change. There are pros and cons to each. Multiple changes may help you make progress faster while a single change may help you gain better intuition from each test.
Now that you’ve chosen what you want to test, it’s time to create your variant. If you're using a no code tool like Nami, it’s easy to create the variant for paywall ab testing.
As a best practice, variant A should be the paywall that is already active in your app so you have a baseline to start with. Variant B contains the changes you want to test.
Next, you need to decide how to allocate traffic to to your variants. It could be as simple as a 50%/50% split or 80%/20% split. The specific granularity of traffic allocation will depend on the tool you’re using. Nami allows any whole number so long as the total equals 100%.
Some considerations when deciding how to allocate traffic:
Your test is running and results are coming in. You’re probably eager to find out the winner. However, just because Paywall B is converting better, doesn’t mean it’s the winner. It might be, but to be sure you need to reach statistical significance.
A statistical significant result is one that has not occurred by random chance. This is why it’s important not to look at those early results which may appear like a conclusion when in fact there’s not yet enough yet to reach such a conclusion.
You might be wondering how long the test will take to reach statistical significance. The answer is somewhat frustrating: it depends. It depends how much traffic each variant is receiving as well as how many conversions you’ve received against that traffic.
You’re looking to exceed a 90% or higher confidence level before taking comfort that the results of the test are known. If you’re interested in the statistics, check out this guide.
Amongst all this statistics talk, there is good news! Most AB testing tools will do the math for you and crown a winner once statistical significance is reached with high confidence.
In this article we’ve talked all about paywall AB testing. The AB naturally means we’re testing one thing against another. This limits the test to just two paywalls.
Marketers who have performed testing in other contexts will likely be familiar with multi-variant testing (MVT). While it may sound appealing to test more things at once (in this case, more paywall variations), it’s not for everyone.
MVT requires much more traffic to deliver a statistically significant result. Given how anemic most mobile app conversion rates are, it’s our recommendation that you stick to AB testing even with a lot of traffic.
There’s so much opportunity to improve without the complexity of MVT. Once you’re chasing single percentage points of optimization, you can consider introducing MVT into your testing arsenal.

The DF-BPA-30 error is a common issue for developers testing in-app purchases or subscriptions on Google Play Store. This error typically relates to billing problems, often linked to invalid or outdated payment methods. Encountering DF-BPA-30 can disrupt testing and prevent developers from completing in-app purchase setups, but resolving it quickly is straightforward with the correct approach.
The DF-BPA-30 error is frequently triggered when the Google Play Store encounters billing information it cannot validate, often due to expired or invalid test payment methods. When testing in-app billing or subscriptions, developers may use test cards or billing profiles that are outdated or incorrectly set up, resulting in this error. Google Play flags the transaction, blocking further processing until the payment method is verified or replaced.
In addition, Play Store payment settings may become misaligned between the Play Console and the device cache, contributing to this error’s frequency during repeated tests.
This error generally appears in the following scenarios:
The DF-BPA-30 error, often tied to billing verification issues, can interrupt in-app purchase testing on Google Play. By following these troubleshooting steps—updating payment methods, clearing cache, re-adding payment profiles, and testing on stable networks—developers can ensure a smooth billing process.
With Nami, however, developers can avoid these complex billing setup issues entirely. Nami’s low-code solutions keep your in-app purchases updated and compliant, so you can focus on building a better app without worrying about ongoing billing updates. Discover how at NamiML.
