Instructions

Follow the detailed instructions below.

To add an app avatar in the Akana API Platform using the API

  1. Log in via the API, POST /api/login operation, using your own email and password in the body of the operation instead of the placeholder values given below.
    • HTTP method: POST
    • URL: https://{hostname}/api/login
    • Accept header: application/json
    • Content-Type header: application/json
    • CSRF header: include it if needed. If you are not sure whether it's needed or not, refer to CSRF Prevention on the Platform.
    • Request Body:
      {
        "email":"MyEmailAddress",
        "password":"MyPassword"
      }
  2. Upload the image to the dropbox, using the POST /api/dropbox/pictures operation. In your API call, you'll need to specify the name and path for the image.
    • HTTP method: POST
    • URL: https://{hostname}/api/dropbox/pictures
    • Content-Type header: multipart/form-data
    • CSRF header: include it if needed. Usually needed for POST operations. If you are not sure, refer to CSRF Prevention on the Platform.
  3. Optional: Specify the sizing dimensions, using the PUT /api/dropbox/pictures/{PictureID} operation. Note that if you make sure your image is the correct size, outside the platform, you can skip this step.

    In your API call, specify the PictureID (DropboxID) that was returned by the previous operation.

    • HTTP method: POST
    • URL: https://{hostname}/api/dropbox/pictures/{PictureID}
    • Accept header: application/json
    • Content-Type header: application/x-www-form-urlencoded
    • CSRF header: include it if needed. If you are not sure whether it's needed or not, refer to CSRF Prevention on the Platform.
    • The request body includes the dimensions of the file. Define the following keys: x, y, w, h (X and Y axes, height and width). See the example below from Postman.

  4. Optional: Review the new image to see how it will look as the avatar, using the GET /api/dropbox/pictures/{PictureID} operation. In your API call, specify the PictureID (DropboxID). The image is returned.
    • HTTP method: GET
    • URL: https://{hostname}/api/dropbox/pictures/{PictureID}
    • Accept header: image/jpeg
    • CSRF header: include it if needed. See CSRF Prevention on the Platform.
  5. Modify the app definition to include the new image, using the PUT /api/apps/{AppID} operation. In your API call, you'll need to specify the AppID, and in the body you'll need to include the app name and the DropboxID.
    • HTTP method: POST
    • URL: https://{hostname}/api/apps/{AppID}
    • Accept header: text/plain
    • Content-Type header: multipart/form-data
    • CSRF header: include it if needed. Usually needed for POST operations. See CSRF Prevention on the Platform.
    • Request Body:
      {
        "Name": "MyAppName",
        "PictureID":"1234"
      }
  6. When done, remember to log out using the POST /api/login/logout operation. Use the following values:
    • URL: https://{hostname}/api/login/logout
    • Accept header: application/json
