Update an existing visualizer

Update visualizer#

To update an existing visualizer record you will need to make a TLS request to the OpenHIM API for the below method and endpoint and supply the updated JSON object for the visualizer record.

Method: PUT
Endpoint: {openhim_url}:8080/visualizers/:visualizerId
Payload: JSON object of the visualizer record

Example#

Note: In the examples below, we are using the token authentication type to authenticate requests

Languages
Sample Data

Before we can send our request to the OpenHIM API we need to ensure that we construct our valid HTTP headers to successfully authenticate with the OpenHIM API.

NodeJS
Bash

Copy the below code at the bottom of your nodejs script that handles the authentication of the OpenHIM headers as described in the authentication section.

Replace the openhimOptions values with the correct implementation details and supply the SampleData payload to submit

// append below code to the "openhim-api.js" script containing the authentication methods. 
// This is described within the authentication section

(async () => {
  const openhimOptions = {
    apiURL: 'https://localhost:8080',
    apiEndpoint: '/visualizers/visualizerId',
    username: '[email protected]',
    password: 'openhim-password',
    rejectUnauthorized: false
  }
  const SampleData = 'SampleData'

  const headers = await genAuthHeaders(openhimOptions)
  
  const options = { 
    method: 'PUT',
    url: `${openhimOptions.apiURL}${openhimOptions.apiEndpoint}`,
    rejectUnauthorized: openhimOptions.rejectUnauthorized,
    headers: headers,
    body: SampleData,
    json: true
  }
  
  request(options, (error, response, body) => {
    if (error) throw new Error(error)
  
    console.log({
      statusCode: response.statusCode,
      body
    })
  })
})()

Execute the below command in your terminal to run the nodejs script

node openhim-api.js

Ensure that you have created your bash script to construct the HTTP authentication headers and send the request to the OpenHIM API as described in the authentication section.

Execute the below command in your terminal where the file is located with the required arguments. Replace the placeholder arguments with the correct implementation details and ensure your SampleData.json file exists with the updated visualizer object.

./openhim-api.sh [email protected] openhim-password -v -X PUT https://localhost:8080/visualizers/visualizerId -d @SampleData.json -H "Content-Type:application/json"

The response status code will be 200 if successful.
