Add certificates using Postman API

You can add and update certificates through an API request using the Postman app.

To add or update certificates, do as follows:

  1. Turn on API configuration, and enter the IP addresses from which you want to send the API requests.
  2. Upload the certificate and private key files to Postman and send an XML request.


You can't get certificates using the Postman API because the data is downloaded in a .tar file. You can use a browser or a Linux command-line interface. See Get certificates using API.

Allow API access

Allow configuration using the API, and enter the IP address from which you want to allow access.

  1. Go to Backup and firmware > API.
  2. Select API configuration.
  3. For Allowed IP address, enter the IP address from which you'll make the API request and click the add button.

    Here's an example:

    Allow API access.

    To find your IP address, go to Log viewer and select Admin in the drop-down list. The source IP address shows the IP address with which you're accessing the web admin console.

  4. Click Apply.
