Public Health Data Operations (PHDO) API Examples

Overview

This repository contains example upload client scripts demonstrating use PHDO upload services.

PHDO Upload API Environment Hostnames

Environment Hostname
Development https://apidev.cdc.gov
Test https://apitst.cdc.gov
Staging https://apistg.cdc.gov
Production https://api.cdc.gov

Setup

Authentication via Secure Authentication Management Services (SAMS)

Users must first authenticate with SAMS before using the Upload API and retrieve an authorization token via a POST request to the /auth API endpoint.

The OAuth request must have the following header:

  • Content-Type: application/x-www-form-urlencoded

The following query parameters must be provided:

  • username - SAMS system account username
  • password - SAMS system account password

Example request: https://<hostname>/oauth?username=<your-username>&password=<your-password>

Provide Environment Variables via Dotenv

Once the hostname has been selected and token retrieved, those values must be set to environment variables for the example scripts to use. These can be set at the command line, or using dotenv. To do this, create a file in the root of this repo called .env.

Add the following lines to the .env file and fill out their values:

AUTH_TOKEN=
DEX_URL=
