Try using the POST method. After that, the other data structures (including array ) will become available. Right now you only see string , boolean , and number because the interface limits the parameter types for the current method.

No, File Repository access does not need to be enabled for files to be publicly accessible. If a file is stored in the File Service and not restricted by permissions, it can be accessed directly via its URL.

The URL you shared:

https://backendlessappcontent.com/.../files/testCSV.csv

works because it is the direct Backendless file URL, which bypasses the custom domain.

Regarding the setting shown in your screenshot — the tooltip there mentions:

“This is the domain that will be used to generate URLs for the files uploaded to your Backendless File repository.”

This setting simply defines which domain Backendless uses when generating file URLs. It does not affect whether the file repository itself is accessible.

When using a custom domain, files are normally accessed through the File Service path, for example:

https://mydomain.com/api/files/testCSV.csv

If possible, could you check whether this URL works for you?

You can also review the custom domain setup here to make sure everything matches the expected configuration: Custom Domain

I use to be able to access the file at mydomain.com/testCSV.csv.

This has stopped working in the past few days. I haven’t made any changes, which is the confusing part on my end.

Thanks for testing that — this helps narrow it down.

With a Backendless custom domain, files are typically accessed through the File Service path. Even if the file is located in the root folder of the File Service, the URL usually looks like this:

https://YourCustomDomain.com/api/files/filename.ext

Could you try accessing the file using that format and see if it works?

Since you mentioned that files can still be downloaded using the Backendless file URL, but anything accessed through the custom domain fails, the issue is likely related to the custom domain routing or configuration.

Could you please also confirm:

1. The exact URL you are using when accessing the file through the custom domain.
2. What response or error you receive (404, 403, redirect, etc.).
3. Whether the domain still shows as active/verified in Manage → Custom Domain.

You can also double-check the setup steps here: Custom Domains

Regards,
Volodymyr

I’ve been testing and it seems related to accessing anything from the custom domain.

If a file is in the root, should I be able to access it at CustomDomain.com/filename.ext?

I uploaded a file to the root directory and cannot access it as described.

Thanks for the report! To help us investigate, could you clarify a few things:

1. Steps to reproduce – Can you describe the exact sequence of actions that leads to the error? (e.g., trigger the plugin → call list2csv → open URL → error appears)

2. File name / path – What is the name or path of the CSV file being generated? Does the error occur with any file, or only specific ones?

3. Custom domain URL – What does the URL look like when you try to open the file through your custom domain? (You can redact sensitive parts)

4. Screenshot clarification – In the screenshot you attached, which service/method is shown? Is it the list2csv call itself, or the subsequent file open/download step?

5. Recent changes – Were there any changes on your end around the time this stopped working (domain settings, SSL certificate, etc.)?

The Backendless file URL still works, so the issue seems to be specific to the custom domain routing — any additional context would help narrow it down quickly.

Thank you for reporting this issue. We investigated the error.

What happened:

The invalid_grant error from Google can occur for several reasons, but the most likely explanation in this case is that the same authorization code was sent to the server more than once. Google’s authorization codes are strictly
single-use — once a code is exchanged for an access token, any subsequent attempt to use the same code will be rejected with this error.

This typically happens when:

• The user refreshes the browser page (F5) after the Google redirect
• The login button is clicked more than once
• Client-side retry logic re-sends the callback request

In any of these cases, the first request would succeed normally, but the second request would attempt to exchange the same code with Google and receive invalid_grant.

Recommendation:

Please ensure the OAuth callback is not being triggered multiple times. Preventing duplicate requests should resolve this issue.

Let us know if you have any further questions.

Volodymyr

This as worked fine for months/years, but stopped working in the last few days or so. I can see the files from the console, and if I access the backendless link for the file, it gets downloaded. I can’t seem to access it through my custom domain any longer.

Thank you for reporting this issue. The invalid_grant error typically occurs due to a temporary hiccup in the authorization exchange process between our servers and Google (e.g., an expired or accidentally duplicated authorization code).

We have escalated this to our team, and they will look into the issue to find out what went wrong.

In the meantime, could you or your client please try the following quick troubleshooting steps?

1. Clear the browser cache and cookies, or try logging in via an Incognito/Private browsing window.
2. Ensure that you only click the “Login with Google” button once, as double-clicking can sometimes invalidate the login code.

If the issue persists after trying this, please let us know. We will update you as soon as our team have more information!

Best regards,
Viktor

Since the benefit of a paid plan will be minimal compared to our allocated budget, we decided it’s better to hit those limits and catch up on work in following days since the load is rarely that high. In the long term, since we have close partners that actually do VPS hosting, we will have the bare-metal to host an instance of the BL Pro community edition, even if that would mean we will migrate flow runner work to API services or other.

I managed to reach it via the search navigation, but I feel like I’m missing a UI link to reach it more conveniently. Please advise.

New operations can be added via a popup only for Codeless services. When you build a JS service, create a service and then using the Coding screen to build and deploy your service:

You’re right that Tier 1 on Scale Fixed caps at 5 requests per minute, which is lower than the free plan’s 50 req/min burst limit. However, the free plan also has a hard limit of 1,000 API requests per day, along with other significant restrictions - 10 data tables, 15,000 database records, 1GB file storage, limited event handlers, and more. So while the free plan allows short bursts of higher throughput, it’s designed for development and prototyping, not for running a production app serving real users throughout the day. All of this information is published on our pricing page and in our documentation - we don’t hide anything about how the plans and tiers work.

I understand that $55/month (Tier 4, up to 50 req/min) may feel like a lot for a small cloud application. But if you consider what you’re getting - a managed database, file storage, business logic hosting, API infrastructure, UI Builder - and compare that to the cost of provisioning and maintaining your own server with equivalent capabilities, you might be surprised how quickly those costs add up and surpass that amount.

You mentioned setting up a self-hosted Backendless Pro instance as an alternative. You’re absolutely welcome to run the Backendless Community Edition for free, but I’d encourage you to go in with realistic expectations about hosting costs. Between compute, storage, networking, backups, and ongoing maintenance, things get expensive quickly in server-land. Unfortunately, we also have bills to pay to keep the platform running, and our pricing reflects the real cost of the infrastructure and services we provide.

Happy to help you analyze your usage and find the right tier if you’d like.

Mark

I’m trying to set up a JS-based API service to run a chronjob (once a week execution), similar to this guide: How to Backup Your Data Tables in Backendless | Backendless or How to Create a Cloud Code Timer in Backendless Console | Backendless

What I’m seeing when I create a new API service with JS is that there is no way to create an operation for the service in JS. Unlike Codeless, where I have a “New Operation” button, with JS I am stuck without being able to do anything.

For comparison:

I just wanted to submit this complaint about the lowest-tier payed plan, which, from my understanding, is the Scale-Fixed plan, capped at Tier-1.

The main reason I wanted to upgrade was to increase limits from 50 requests per minute, and to remove the free-plan banner on the UI-builder web app.

The story of how I got here:

In January, I was burned pretty badly by subscribing to the scale variable plan. I didn’t realise that high levels of requests, that would happen while development, would push me into higher tiers. While I expected a bill of $15 per month, I ended up with a bill of $70. Thankfully the person I’m building the app for was happy to cover those costs, but from my side it felt very unfair.

I then switched to the Scale Fixed plan. The next day I realised I had messed up again, since I had an invoice of $22 come in, which meant I was paying more for one day than I would expect for an entire month. I quickly found out that I needed to cap the requests at “Tier 1” to limit unexpected price hikes. The app is not especially a high-usage app, and we can optimise further, so I left it like that.

Now, my client is telling me that the app is not working at all. Indeed, I have realized that the “Tier 1” has only 5 API requests per minute, which is not enough to load a web page if it includes icons, scripts, and custom components. Thus I’m paying for a completely broken service.

I’m saying this as my only resort now is to switch back to the free plan, which has 50 requests per minute, or to self-host a backendless pro instance, which I’m also setting up in parallel. This seems completely counter-intuitive as I’d expect an easier time and a better service if I was paying, even for an entry-level pricing.

Please consider this as feedback for your services and pricing. If you have any questions I will be happy to answer.

One of our clients tried to log in using Google but encountered the following error:
Code: 3109 Error during obtaining of access token. Response from OAuth2 provider server: Bad Request { “error”: “invalid_grant”, “error_description”: “Bad Request” }

Could you please help investigate and advise on a resolution?

To customize the highlight color, you need:

1. Go to Theme → Extensions
2. Create a new extension
3. Add the following CSS:

  .bl-data-table .bl-data-table-row.Mui-selected {
    background-color: yellow;
  }

Just replace yellow with any color you’d like, for example #ffeb3b, green, rgb(255, 235, 59) . Any standard color format works perfectly.

Hope this helps. Feel free to reach out if you have any other questions.

Kind regards,

No, there is no renewal lag. I suspect the issue with the DNS somewhere on the side of the visitors who experienced the issue.

I checked the certificate for https://fracturebook.ota.org/, and it is valid:

I also ran a check here:

Can you open your site and check if you get a certificate error?

I am glad you worked out a policy for collaborative editing. Indeed, it is important to make sure you’re not stepping on each other toes while working on the same service (i.e. deployment model). My recommendation is whenever someone takes over a service, make sure to completely reload the console to ensure you have the latest changes from the server. Otherwise, the following may happen:

1. engineer A starts working on a service
2. engineer B tries to open the same service for editing (see the warning above and waits)
3. engineer A deploys the service and informs B about it
4. engineer B starts editing

The problem here is that engineer B is looking at the version of the service that does not have changes from engineer A. As a result, any changes deployed in step 3 will be wiped out when engineer B deploys theirs.

Mark

The certificate has been reissued.

Whenever we need to update a method in a service and someone else is already working on that specific service, we receive an alert like this. In that case, we usually wait for the other user to finish their update and save their progress before another user starts editing.

As for the log of codeless changes, I’m not sure which one you are referring to, but there is a changelog in each method. However, the log gets removed after some time.

Thank you so much for checking!

I thought that these were supposed to be renewed automatically?

This is a production site, could somebody please fix it A.S.A.P.

Mike

For example:

1. you a list of items [{id:1}, {id:2} {id:3}]
2. the list is used in the repeater
3. when you opened a modal you get the item with id=1 and put (cloned) it to the pageData
4. after changing the cloned data in the pageData you need to put it back to the repeater list data
5. using the codeless block MapItems you create a new list with replaced item
6. then you assign the list to the repeater

It is a poor wording of the message. The system is designed to clear any pending balance from your monthly billing cycle whenever you run any import or export operations.

I checked the activity log and I see multiple instances where the service is regularly updated by you and Kean, at times within 25 minutes between the updates (on March 2nd for example) - see the screenshot below. If the service logic is fetched by Kean before you deploys the changes, then Kean’s changes will overwrite yours. This is what most certainly caused the "logic changes reversal’.

Both you and Kean should have log of codeless changes on your corresponding machines. You should be able to use it to understand when the overwrite happened.
