# Postman collection import

[Postman](https://www.postman.com/) is a collaboration platform for API development, it makes testing your API easy, for instance by importing open API or swagger definitions. 

!!! Warning
    Postman exports are usually missing headers like **Content-type** and some others. Also some items like postman scripts cannot be converted in JMeter/OctoPerf. These elements will have to be added again in OctoPerf but the bulk of your Postman collection will be properly imported.

## Import Open API/Swagger

Even if you are not using Postman on a regular basis, it can also be used to import [Open API](https://www.openapis.org/) and [Swagger](https://swagger.io/) definitions, the procedure is [available here in their documentation](https://learning.postman.com/docs/integrations/available-integrations/working-with-openAPI/). It can then be exported as a postman collection and imported in OctoPerf thus providing a way to also import these two specifications in OctoPerf.

## Export postman collection

To retrieve your Postman requests inside OctoPerf you need to export the collection as a JSON from within Postman. This can be done by right clicking on it and selecting export:

![export](https://api.octoperf.com/doc/design/create-virtual-user/img/postman/export.png)

OctoPerf requires the v2.1 JSON Collection format:

![export-collection](https://api.octoperf.com/doc/design/create-virtual-user/img/postman/export-collection.png)

You can then proceed to import it inside OctoPerf.

## Create Virtual User: Import collection

Import the previously saved .json file on OctoPerf:

![Create Virtual User from Postman collection](https://api.octoperf.com/doc/design/create-virtual-user/img/postman/import-postman-collection.png "Create your virtual user from Postman collection")

Simply drop the file in the JSON area or use the _Choose File_ button. The download starts automatically.

### Ad blocker

By default OctoPerf will filter a certain number of URLs based on a few blocklists:

- [https://github.com/gieljnssns/Social-media-Blocklists](https://github.com/gieljnssns/Social-media-Blocklists),
- [https://www.securiteinfo.com/administration-systeme-et-reseau/outils/ultimate-hosts-blacklist.shtml](https://www.securiteinfo.com/administration-systeme-et-reseau/outils/ultimate-hosts-blacklist.shtml)

Make sure to `Disable ad blocker` if you prefer to keep everything.
