Data Compliance returns invalid_request 400

I am trying to post data compliance after receiving the deauthorization event payload. I am following the instructions from these documents:

POST /auth/data/compliance
Data Compliance

The request returns this:

{"reason":"Invalid Request","error":"invalid_request"}

Which App Type (OAuth / Chatbot / JWT / Webhook)?

Which Endpoint/s?
Data Compliance API

How To Reproduce (If applicable)
I send POST to the URL that was in the document

client_id = ENV['ZOOM_APP_KEY']
client_secret = ENV['ZOOM_APP_SECRET']
headers_secret = Base64.strict_encode64("#{client_id}:#{client_secret}")

deauthorization_event = ZoomDeauthorizationEvent.find(deauthorization_event_id)

data_compliance_link = ""

response =
  body: {
    "client_id": deauthorization_event.client_id,
    "user_id": deauthorization_event.user_id,
    "account_id": deauthorization_event.account_id,
    "deauthorization_event_received":  {
      "user_data_retention": deauthorization_event.user_data_retention,
      "account_id": deauthorization_event.account_id,
      "user_id": deauthorization_event.user_id,
      "signature": deauthorization_event.signature,
      "deauthorization_time": deauthorization_event.deauthorization_time,
      "client_id": deauthorization_event.client_id
    "compliance_completed": true
  headers: { 
    "Authorization": "Basic #{headers_secret}",
    "Content-Type": "application/json",
    "cache-control": "no-cache"

I am getting 400 response.code

Additional context
I am testing through ngrok, with production credentials provided by ZOOM.

I read all the posts from here, and it often seems like header problems (misspelling, etc)

Hey @Thrive,

Thank you for reaching out to the Zoom Developer Forum. Please send an email including the endpoint, request body and headers that are used to reproduce the issue to and we’ll look into this further.


Thanks @MaxM,

The compliance endpoint returned 200 and I was able to get the response body.

It might have been the base64 not working correctly on my end. In any case, it started working.
