SharinPix Mobile App: Retrieve User Information When Uploading Photos (Developer-Oriented)

The SharinPix mobile app uses tokens to authenticate itself and upload photos that can be viewed on Salesforce. 

Since the app is built for offline use, the tokens are usually generated beforehand and stored in Salesforce fields on records. Multiple users can also upload photos to a single Salesforce record. As such, the tokens cannot be tied to any specific user to avoid relating the user to all photos uploaded by anyone to the record.  Thus, the tokens are "anonymous".

This article demonstrates how to:

  1. Pass the current user's identifier in the URL.
  2. Retrieve them when the photos are uploaded. 
  3.  Save the user identifier in a custom field on the SharinPix Image record.

Note:

The user identifier will be saved on a SharinPix Image record. To enable the use of the SharinPix Image object, kindly ensure that the SharinPix Image Sync has been activated on the Salesforce object on which users are uploading photos.

For more information on SharinPix Image Sync, refer to this article: 

What is SharinPix Image Sync?

For steps on how to activate the SharinPix Image Sync on an object, refer to this article:

Setup SharinPix Image Sync

Tips:

  • For more information on SharinPix tokens and how they work, refer to this article: Working with SharinPix Tokens
  • This article also applies to photo uploads launched from the Salesforce Field Service mobile app.

To retrieve the user information in anonymous tokens, you will need to:

  1. Create a Flow to capture the user information and launch the SharinPix app to upload photos.
  2. Create an Apex class to retrieve and save the user info in a Salesforce field.
  3. Configure a Webhook to capture the mobile upload requests.

Create the Flow

This section demonstrates how to create a Flow that will capture the username of the user opening the SharinPix mobile app to upload photos.

    • Click Done

How to use the flow:

Tips:

  • The user values passed in the URL can be modified as desired.
  • Other values can be passed in the SharinPix URL. The value, record_id, for instance, will move the uploaded photo to the specified record ID:

sharinpix://upload?token={!WOLI.SharinPix_Token__c}&record_id={!WorkOrderID}

Create the Apex Class

Note:

It is important that the value passed in the URL is saved in a custom field on the SharinPix Image object and not in one of the fields managed by the SharinPix package.

This is because the SharinPix Image object's managed fields can be updated after performing SharinPix actions such as image synchronizations. Updating these manage fields outside the SharinPix package may lead to data alterations.

The type of field to be used will depend on the use case. In the example below, a lookup field to the User object has been created to save the username corresponding to the user ID passed.

Next, create an Apex class to will retrieve the user information passed to the user_id parameter and save the value in the custom field on the related SharinPix Image record. 

Here's the sample code for the Apex class:

trigger SharinPixImageUserIdReplace on sharinpix__SharinPixImage__c (before insert) {
    Map<String, Object> metadatas;
    String appUrl;
    List<sharinpix__SharinPixImage__c> updatedUserName = new List<sharinpix__SharinPixImage__c>();
    for (sharinpix__SharinPixImage__c image : Trigger.new) {
        if (String.isBlank(image.sharinpix__Metadatas__c)) { continue; }
        try {
            metadatas = (Map<String, Object>) JSON.deserializeUntyped(image.sharinpix__Metadatas__c);
            appUrl = String.valueOf(metadatas.get('sharinpix_mobile_app_url'));
        } catch (Exception e) {
            // No JSON in field
            continue;
        }
        if (String.isBlank(appUrl)) { return; }
        if(!(appUrl.contains('&user_id='))) {return;}

        //Retrieve the user ID from the metadata
        List<String> urlParams = appUrl.split('&user_id=');
        Id username = urlParams[1].substring(0,18);

        //Update the custom field with value stored in variable username.
        image.Uploaded_By__c = username;
    }
}

Create the SharinPix Webhook

For this implementation to work, you will need either a SharinPix Webhook of type Upload Done or New Image.

To verify your Webhook settings, go to the SharinPix Administration Dashboard, then click on Webhooks.

The Webhook settings should be as follows:

  • Action type: apex_method
  • Class name: sharinpix.ImageSyncMigration
  • Method name: synchronize
  • The Webhook should be either of type Upload Done or New Image

If no Webhook has been created for your organization, create one as indicated above.

Tip:

For more information on SharinPix Webhooks, refer to this article: SharinPix Webhooks
