Transferring API Collections Between Postman and Talend API Tester

Previously the author used Postman for API testing and now wants to switch to Talend API Tester, raising the question of how to migrate existing collections.

First, a new collection A is created in Postman, a request is added, and the request URL is replaced with the variable {{host}} so that changing the domain only requires updating the environment variable.

Postman already supports environment variables; after adding one named host , the request continues to work without hard‑coding the domain.

To share a collection with others, right‑click the collection, choose Share Collection , obtain a public link, and send that link to teammates. They can import the collection by pasting the link into Postman's import dialog, choosing to replace or duplicate if the collection already exists.

For exchanging data with Talend API Tester, first install the Talend API extension (available from the Chrome Web Store; an offline download link crxdl.com is provided). After installation, use the Import function in Talend API to import a Postman Collection V2 file.

Export the collection from Postman (right‑click → Export → Collection V2), then import the exported JSON file into Talend API. Because Talend API does not automatically recognize Postman's environment variables, manually create a host variable in Talend API and copy the value from Postman's environment.

Once the variable is set, sending the request from Talend API succeeds, demonstrating that the collection and its data have been successfully transferred.

The article concludes that Postman ↔ Postman and Postman ↔ Talend API data exchange is straightforward, and most other API testing tools likely offer similar capabilities.
