Postman

Postman is a free tool for conveniently working with APIs in a graphical interface. It is available for Windows, macOS, and Linux.

You can follow the installation instructions described on Postman.

Steps

  1. In the Authorization tab for a request, select AWS Signature from the Type dropdown list. Specify where Postman should append your authorization data using the Add authorization data to drop-down menu.

  • If you select Request Headers, Postman populates the Headers tab with Authorization and X-Amz- prefixed fields.

  • If you select the Request URL, Postman populates the Params tab with authentication details prefixed with X-Amz-.

Note: The parameters listed below contain confidential information. We recommend using variables to keep this data secure while working in a collaborative environment.

  1. To get the Access Key and Secret Key, log in to the DCD, go to Menu > Storage > IONOS S3 Object Storage > Key management.

Advanced fields are optional, but Postman will attempt to generate them automatically if necessary.

  1. For AWS Region, leave the field blank as the region from the endpoint will be used.

  2. For Service Name, enter s3. The name of the service that receives the requests.

  3. For Session Token, leave the field blank. This is only required when temporary security credentials are used.

  4. Setup completed. Now check the S3 API description to get the right endpoint to call.

Note: You need to use the correct endpoint URL for each region (see the list of available endpoints).
