Add and manage client certificates in Hoppscotch Desktop App or in Hoppscotch Web App using the Hoppscotch Agent as an interceptor to authenticate your identity when connecting to secure APIs.

​
Prerequisites

Before you begin, ensure you have the following:
  • Either the Hoppscotch Desktop App installed on your system, or if you are using the Hoppscotch Web App, make sure the Hoppscotch Agent is installed and configured.
  • A valid Client Certificate in one of the following formats:
    • .pem Certificate
    • .pfx/.pkcs12 Certificate
  • The corresponding private key file, if the certificate is in .pem format.

​
Adding Client Certificate

  1. Open Hoppscotch’s settings page from the side bar.
  2. Within Interceptors section, locate the Client Certificates action:
    • Under Native settings if using the Desktop App.
    • Under Agent if using the Web App.
  3. Click on the option to add a new client certificate and select the type of certificate you want to add: .pem or .pfx/.pkcs12.
  4. Upload Certificate Files
    • .pem Certificate: Choose the certificate file (.crt/.cer/.pem) and upload the private key file (.key/.pem) in the designated field.
    • .pfx/.pkcs12 Certificate: Choose the .pfx/.pkcs12 file. You may need to enter the password associated with the certificate file.
  5. After uploading the certificate files, click on the save button to store the settings.

Using Client Certificate

Once you add the certificate, it will automatically be applied to the configured domain whenever you make an HTTP request. If you wish to disable the certificate for a domain, simply uncheck the corresponding checkbox.

​
Removing a certificate

Remove a certificate when no longer needed for sending requests by selecting the delete icon located next to the certificate associated with a specific domain.
