Send a file via Redox Data Model API

If you haven’t already, review best practices for sending a file to your connection. This article contains instructions for how to send a file with the Redox Data Model API specifically. You can either:

• embed a file less than 10 MB directly in the Notes, Results, or Media data models; or
• upload a file to a Redox blob endpoint, then include the URL reference in the Notes, Results, or Media data models. 

Send a file less than 10 MB to your connection with the Notes or Results data model. Which data model you use depends on the context of the file, though. 

• The Notes data model can send a provider's clinical notes or a general file related to the patient (e.g., a signed consent form or a patient-related JPG file).

  What to send with a Notes file

  With the Notes data model, most EHR systems require that you provide the patient identifier and basic demographic information (e.g., name, date of birth). But you may need to include some of these bonus details:

  • unique note ID
  • note type
  • provider authentication and authorization (i.e., whether the physician has authenticated and authorized the note to add it to the patient's chart)
  • visit number (to associate a note with a specific visit or area in the EHR system)

• The Results data model can send a file with a patient's test results or lab-related data. 

Each data model has their own supported fields and requirements. In this how-to, we only highlight the required fields for each, but check out our data model reference docs for full specs.

1. Encode the file as a base64 encoded string.
2. Populate the required document fields to include the encoded file in your request: 
   • In the Note.ContentType field, enter Base64 Encoded (as one of the supported values from the value set).
   • In the Note.FileContents field, insert the base64 encoded string for the file.
   • In the Note.FileName field, enter the name of the file.
   • In the Note.DocumentType field, enter the type of document that should be associated with the file (e.g., consent form, treatment plan).
   • In the Note.DocumentID field, enter the unique identifier for this document.
   • In the Note.Provider.ID field, enter the ID of the provider responsible for the document.
3. Populate any of the other fields of the Notes request with relevant data. Refer to the Notes schema for all the available fields.

1. Encode the file as a base64 encoded string.
2. Populate the required document fields to include the encoded file in your request: 
   • In the Orders[].Results[].Value field, insert the base64 encoded string for the file.
   • In the Orders[].Results[].ValueType field, enter Encapsulated Data (as one of the supported values from the value set).
   • In the Orders[].Results[].FileType field, enter a valid file type.
3. Populate any of the other fields of the Results request with relevant data. Refer to the Results schema for all the available fields.

1. Encode the file as a base64 encoded string.
2. Populate the required document fields to include the encoded file in your request:
   • In the Media.FileType field, enter a valid file type.
   • In the Media.FileName field, enter the name of the file.
   • In the Media.FileContents field, insert the base64 encoded string for the file. 
   • In the Media.DocumentType field, enter the type of document that should be associated with the file (e.g., consent form, treatment plan).
   • In the Media.DocumentID field, enter the unique identifier for this document.
   • In the Media.Provider.ID field, enter the ID of the provider responsible for the document. 
   • In the Media.Availability field, enter the value that describes the file's availability: Available, Unavailable, Obsolete, Deleted, Cancelled.
3. Populate any of the other fields of the request with relevant data. Refer to the Media schema for all the available fields.

For larger files, you must first upload them to Redox. Then, you can refer to the file in your requests.

1. Locate the file you want to upload.
2. Send your file to the Redox upload endpoint: You must authenticate the API key like you would for a typical Data Model API request. Learn how to authenticate and initiate a request. 

   Development not available for free accounts

   Upload functionality isn’t available in development environments if you have a free Redox account. Talk to your account manager about upgrading if you want to upload files from development.

   Example: Upload a file to Redox with the Data Model API

   bash

   Copy

   1
   curl https://blob.redoxengine.com/upload \
   2
     -H "Authorization: Bearer " 
   3
     -X POST \
   4
     -F file=@file.pdf
3. If successful, you receive a 201 Created status with the URI reference to your file in the body of the response.
4. Send the uploaded file via the same process for embedding a file. You only need to include the URI from the previous step instead of the base64 encoded file within the request. 
5. To check if the file uploaded successfully, log in to the Redox dashboard and check the log for the request. The uploaded file displays under the Process tab of the log.
