Authorization

• Provide a hard coded API Key for authentication

Query Parameters

• if process=true place the request body in the bullmq message queue. The queue worker should then add the PROCESSED status to the statusHistory array in the response:

  {
    "status": "PROCESSED",
    "user": {
      "id": "775671ff-f70d-415d-b523-f50b05139ac9",
      "identifier": "admin@admin.com"
    },
    "createdAt": "2020-04-20T03:11:23.762Z"
  }

• if process=false simply return the response, do not add the extra status since the job is not added to the queue
• if data=none, the data object in the response should be empty
• if data=base64, the data object in the response should be the request body in base 64 encoded
• if data=full, the data object in the response should be the entire request body

Request Body

• for the POST request body, simply use the body provided in the spec
• validate data structure to see if fields are not provided

Response Object For the response of the POST and GET requests:

• if process=true:

the result object in the response should be:

• the source object should indicate what user sent the request
• the checks array in the response should be empty
• the notes array in the response should be empty
• use valid time stamps
• note how when process=false the statusHistory does not have the PROCESSED status

Response Status

POST

• Only code for 201, 400, and 401.

Data Structures

You can organize the data structures in any way you want.

Bonus

Write a one command cli in go that allows for making the post request:

charge post organizations --authorization=MY_API_KEY --body=body.json

Questions
