Why Your Bruno Import of Postman Collection Failed and How to Fix It

Are you trying to import a Postman collection into Bruno and hitting a wall? You’re not alone! The frustration is real when you’re all set to get things done, and suddenly, the process comes to a screeching halt. But don't worry, we're here to help you troubleshoot this issue and get you back on track.

💡
Before we dive in, let me give you a quick heads-up: if you're struggling with API testing tools like Postman and Bruno, you might want to check out Apidog as a great alternative. Download Apidog for free, and it might just save you from some of these headaches.

Now, let’s get to the root of the issue.

Understanding the Bruno-Postman Relationship

Before jumping into the possible reasons behind the import failure, it's essential to understand the relationship between Bruno and Postman. Both tools are designed to make API testing easier, but they have different ways of handling collections, variables, and environments.

These tools, while similar in purpose, handle data structures differently. This difference can sometimes lead to compatibility issues when importing a Postman collection into Bruno.

Why the Import Might Fail

Here are some of the most common reasons your Postman collection might fail to import into Bruno:

1. Compatibility Issues

Not all versions of Postman collections are compatible with Bruno. Postman collections have undergone several updates over the years, and some of these updates may not be fully supported by Bruno yet.

2. Large or Complex Collections

Another common issue is the size and complexity of the collection you’re trying to import. Large collections with multiple folders, environments, and variables can be overwhelming for Bruno, leading to a failed import.

3. Incorrect File Format

Sometimes, the issue is as simple as trying to import the wrong file format. Postman collections are typically exported in JSON format, but if the file was altered or saved incorrectly, Bruno may not be able to process it.

4. Bruno's Limitations

As a newer tool, Bruno might have some inherent limitations compared to a more mature tool like Postman.

5. Configuration Mismatches

Configuration mismatches between Postman and Bruno can also be a culprit. If the environments or variables are set up differently in Bruno, the collection might not import as expected.

How to Troubleshoot and Fix the Issue

Now that we’ve covered the potential reasons for the import failure, let’s explore some ways to troubleshoot and fix the issue.

1. Check Postman Collection Version

First things first, check the version of the Postman collection you’re trying to import.

2. Simplify the Collection

If the collection is large or complex, consider simplifying it before importing it into Bruno.

3. Validate the JSON File

Make sure the JSON file is in good shape before attempting to import it into Bruno.

4. Adjust Bruno Settings

Sometimes, tweaking Bruno’s settings can help it better handle the import.

5. Manually Recreate the Collection

If all else fails, you might need to manually recreate the collection in Bruno.

Why Apidog is a Better Alternative

Now, let’s circle back to what we discussed earlier. Postman’s gradual shift away from free-tier users has left many feeling squeezed—frustrated with the limitations imposed to nudge them into paid plans. This shift is a critical pain point, especially when you’re dealing with issues like import failures in Bruno.

That’s where Apidog steps in as a much better alternative. Unlike Postman, Apidog remains committed to supporting all users, regardless of whether they’re on a free or paid plan. With Apidog, you get:

Import Data into Postman

When your team is using Postman and needs to transfer data or share project configurations, you can easily import data previously exported from Postman, including collections, environments, data dumps, and globals.

Postman automatically recognizes Postman-specific data during the import process, simplifying the entire workflow.

Step 1. Open Postman and navigate to the Collections tab on the left-hand side. Click on the "Import" button located in the top-left corner of the screen.

Import

Step 2. In the "Import File" modal, click on the "Choose Files" button and select the Postman collection file you need to import. Or you can

Import File

Step 3. Once the file has been selected, click on the "Import" button to initiate the import process.

Step 4. After the import process is complete, you should see your newly imported collection listed in the Collections tab.

Newly Imported Collection

Postman's new plans restrict Free and Basic users to 25 runs/month, with 250 for Professional and unlimited for Enterprise. Frustrated by these limits on running local collections, many developers are switching to other API tools. If you're in the same boat, let's move on to export the data from data to local.

Export Postman All Collections

Step 1. Open Postman and navigate to the collection you want to export. Click on the ellipsis (...) icon next to the collection name.

Export

Step 2. Select "Export" from the drop-down menu. Choose the format in which you want to export the collection. Postman supports a variety of formats including JSON, CSV, and YAML.

Export Collection

Step 3. Choose the location on your computer where you want to save the exported file.

Step 4. Click "Save" to export the collection.

Export Postman All Collection

In Postman, accessing the Data tab via Settings allows you to export all Collections, Environments, Globals, and Header Presets into a single zip file.

Navigate to Settings > Data> Request Date Export within the app. Upon selecting "Export Data," you'll be directed to an area where you can download all your Postman workspace data.

You'll receive an email notification when the data is ready for download. Depending on the data size, refreshing the page will display the download status until the Download button appears for retrieval.

Alternative Method: Import Postman Collection in Apidog

Step 1. Log into Apidog, select "Settings" from the left menu, and then select "Import " to import the exported file as displayed in the image.

Step 2. Select "Postman" and upload file from downloads. In the latest version of Apidog 2.4.9, you can import Postman data, including one `collection` and multiple `environments` in a single import.

Import Postman

Step 3. Upload output data source from Postman. Click “Confirm” as displayed below.

Step 4. After importing your Postman collection into Apidog, you can easily manage it.

You'll have full access to your requests and can modify them as needed. Additionally, requests can be organized into folders, making it easier to navigate through your collection. Overall, Apidog provides a user-friendly interface for managing and organizing collections.

Conclusion

Importing a Postman collection into Bruno doesn’t have to be a painful experience. With the right troubleshooting steps, you can overcome most issues, whether they’re related to compatibility, file size, or configuration differences.

But let’s be real—if you’re finding yourself constantly battling with these kinds of issues, it might be time to make the switch to a more user-friendly tool like Apidog. After all, why put up with being squeezed for money when there’s a better option out there?
