External Collection Data Not Syncing Properly with My Website

[joeroot]

Hi Adalo Community,

I’m working on integrating my Adalo app with my website, but I’ve run into an issue with external collections not syncing data as expected. Here are the details:

Problem Details:

1. I’ve connected an external collection using the REST API to fetch data from my website’s backend. The API works fine in Postman and returns the expected JSON.
2. On Adalo, the data is displayed correctly in the Adalo editor, but when the app is published, some records don’t show up on the live site.
3. Occasionally, the app returns a “Data Fetch Failed” error, even though the same request works perfectly when tested independently.

Troubleshooting Attempts:

• Verified that the API URL, headers, and authentication details are correct.
• Checked rate limits on my API server, which are well below the limit.
• Refreshed the external collection and republished the app, but the issue persists.
• Tested the same integration with another front-end app (not Adalo), and it works fine.

Questions:

1. Are there specific limitations on the size of external collections or API response payloads that could cause this issue?
2. Could this be a caching issue in Adalo, and is there a way to manually clear or refresh the cache?
3. Is there a best practice for structuring API responses (e.g., pagination, headers) to ensure compatibility with Adalo?

Any advice or insights would be greatly appreciated! I’m looking forward to resolving this so I can ensure a seamless experience for my users.

Thank you!

The same thing happens to me, I sent a support ticket and they tell me that it works fine, but when I use it it doesn’t work…

It runs fine but it doesn’t save the result of the query either in the input or in the logged in user… it is causing us problems and delays in development

Thanks for sharing your experience—it’s reassuring (in a way) to know I’m not the only one facing these issues! It does sound like we’re encountering a similar problem, and it’s frustrating when everything seems to work fine during testing but not in production. we can escalate this collectively to Adalo’s support team with detailed logs or examples to help them investigate further. Here is the URL https://capprocutapk.com/ Let’s keep each other updated if we find a solution—it’ll definitely save time for both of us and others in the community! Looking forward to hearing how things go on your end.
