Getting started with our FHIR Converter API is pretty easy, you’ll just need take the following steps:

  1. Create a developer account.
  2. Generate an API key.
  3. Convert C-CDA to FHIR.
  4. Request Production access.

Let’s get into it! 🤘

1. Create a developer account

Click me to go to the developer dashboard!

This will take you to the Metriport developer dashboard where you can create your Metriport account, if you don't have one already.

2. Generate an API key

Once you’ve created an account and confirmed your email, you’ll be taken to the dashboard home page. From here, take the following steps to get your API key:

  • Toggle the Sandbox switch in the Dashboard navbar to enter Sandbox mode (learn more about this here).
  • In the left hand menu, click Developers.
  • On the Developers page, you’ll be able to click the “Generate Secret Key” button.

This Secret Key will allow you to start making requests to the Metriport API. Treat this like a password, and keep it somewhere safe! You can read the API Keys page to learn more about API key security best practices.

If you believe your key has been compromised, you can always revoke it and then generate a new one on the Developers page by clicking the trash button beside the key.

3. Convert C-CDA to FHIR

Essentially, you’ll just need to send a POST request to the Convert C-CDA to FHIR endpoint, with the body containing a valid C-CDA (R2.1) XML document to convert:

<?xml version="1.0" encoding="UTF-8"?>
<ClinicalDocument xmlns="urn:hl7-org:v3">
    <!-- contents -->

You can use this example C-CDA from HL7 for testing purposes.

Since C-CDAs correspond to a particular patient, you should also specify the patientId query param to match your patient’s identifier.

You’ll get back a FHIR R4 Bundle back, with entry containing an array of FHIR R4 Resources being the outcome of the conversion.

    "resourceType": "Bundle",
    "type": "batch",
    "entry": [
            "fullUrl": "urn:uuid:adc44b9c-3083-396f-877f-463120f6b26a",
            "resource": {
                "resourceType": "Location",
                "id": "adc44b9c-3083-396f-877f-463120f6b26a",
                "name": "Good Health Urgent Care"

See the Convert C-CDA to FHIR endpoint in our API reference for more details.

4. Request Production access 🚀

To start using the Convert API for production workloads, you can take the following steps to request production API access:

  • In the left hand menu, click Products & Billing.
  • Click Get Started on the Converter API product.
  • Press Book an Intro Call and select a time and a date to talk to us.

After the call, we will promptly setup your account for production access.
