MongoDB Atlas Admin

Manage MongoDB Atlas infrastructure programmatically via the Atlas Administration API v2.

Authentication

Atlas API uses HTTP Digest Authentication with API keys or OAuth2 with service accounts.

API Keys (Legacy but simpler)

# Set credentials
export ATLAS_PUBLIC_KEY="your-public-key"
export ATLAS_PRIVATE_KEY="your-private-key"

# All requests use digest auth
curl --user "${ATLAS_PUBLIC_KEY}:${ATLAS_PRIVATE_KEY}" \
  --digest \
  --header "Accept: application/vnd.atlas.2025-03-12+json" \
  --header "Content-Type: application/json" \
  "https://cloud.mongodb.com/api/atlas/v2/..."

Service Accounts (OAuth2 - Recommended)

# Get access token
TOKEN=$(curl -s --request POST \
  "https://cloud.mongodb.com/api/oauth/token" \
  --header "Content-Type: application/x-www-form-urlencoded" \
  --data "grant_type=client_credentials&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}" \
  | jq -r '.access_token')

# Use token (valid 1 hour)
curl --header "Authorization: Bearer ${TOKEN}" \
  --header "Accept: application/vnd.atlas.2025-03-12+json" \
  "https://cloud.mongodb.com/api/atlas/v2/..."
