Infisical Sync Expert Knowledge

1. Infisical API Reference

Base URL

All requests go to $INFISICAL_URL. This is the self-hosted instance base URL, e.g. https://infisical.example.com.

Authentication — Universal Auth

Infisical uses Machine Identities with Universal Auth for agent-to-agent communication.

Endpoint: POST /api/v1/auth/universal-auth/login

Request:

{
  "clientId": "<INFISICAL_CLIENT_ID>",
  "clientSecret": "<INFISICAL_CLIENT_SECRET>"
}

Response (success):

{
  "accessToken": "eyJ...",
  "expiresIn": 7200,
  "accessTokenMaxTTL": 43200,
  "tokenType": "Bearer"
}

curl example:

RESPONSE=$(curl -s -X POST "$INFISICAL_URL/api/v1/auth/universal-auth/login" \
  -H "Content-Type: application/json" \
  -d "{\"clientId\":\"$INFISICAL_CLIENT_ID\",\"clientSecret\":\"$INFISICAL_CLIENT_SECRET\"}")

ACCESS_TOKEN=$(echo "$RESPONSE" | python3 -c "import sys,json; print(json.load(sys.stdin)['accessToken'])")

Token lifetime: expiresIn seconds (usually 7200 = 2 hours). Re-authenticate when expired.

List Secrets

Endpoint: GET /api/v4/secrets

Query parameters:

Param	Required	Description
`projectId`	Yes	Infisical project ID
`environment`	Yes	Environment slug (e.g. `prod`, `staging`, `dev`)
`secretPath`	No	Path prefix, default `/`
`includeImports`	No	Include imported secrets, default `false`
`recursive`	No	Include secrets in sub-paths, default `false`

curl example:

curl -s -X GET \
  "$INFISICAL_URL/api/v4/secrets?projectId=$PROJECT_ID&environment=$ENVIRONMENT&secretPath=/" \
  -H "Authorization: Bearer $ACCESS_TOKEN"

Response shape:

{
  "secrets": [
    {
      "id": "uuid",
      "version": 1,
      "secretKey": "DATABASE_URL",
      "secretValue": "postgres://...",
      "secretComment": "",
      "environment": "prod",
      "workspace": "uuid"
    }
  ],
  "imports": []
}

Parse with:

echo "$RESPONSE" | python3 -c "
import sys, json
data = json.load(sys.stdin)
for s in data.get('secrets', []):
    print(s['secretKey'])
"

Create or Update a Secret

The API does not provide a single upsert endpoint. POST creates only (returns 409 if the secret already exists); PATCH updates only (returns 404 if missing). Use the create-then-update pattern:

Step 1 — Try to create (POST)
Endpoint: POST /api/v4/secrets/{secretName}

Request body:

{
  "projectId": "<PROJECT_ID>",
  "environment": "<ENV>",
  "secretValue": "<VALUE>",
  "secretPath": "/"
}

HTTP_STATUS=$(curl -s -o /tmp/infisical_response.json -w "%{http_code}" \
  -X POST "$INFISICAL_URL/api/v4/secrets/$SECRET_NAME" \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d "{\"projectId\":\"$PROJECT_ID\",\"environment\":\"$ENVIRONMENT\",\"secretValue\":\"$SECRET_VALUE\",\"secretPath\":\"/\"}")

Returns 201 on success.

Step 2 — If 409, update via PATCH
Endpoint: PATCH /api/v4/secrets/{secretName}

if [ "$HTTP_STATUS" = "409" ]; then
  HTTP_STATUS=$(curl -s -o /tmp/infisical_response.json -w "%{http_code}" \
    -X PATCH "$INFISICAL_URL/api/v4/secrets/$SECRET_NAME" \
    -H "Authorization: Bearer $ACCESS_TOKEN" \
    -H "Content-Type: application/json" \
    -d "{\"projectId\":\"$PROJECT_ID\",\"environment\":\"$ENVIRONMENT\",\"secretValue\":\"$SECRET_VALUE\",\"secretPath\":\"/\"}")
fi

Returns 200 on success. Any other status code is an error.

Important: URL-encode the secret name if it contains special characters.

Delete a Secret

Endpoint: DELETE /api/v4/secrets/{secretName}

Query parameters: projectId, environment, secretPath (default /)

curl example:

curl -s -X DELETE \
  "$INFISICAL_URL/api/v4/secrets/$SECRET_NAME?projectId=$PROJECT_ID&environment=$ENVIRONMENT&secretPath=/" \
  -H "Authorization: Bearer $ACCESS_TOKEN"

List Accessible Projects (Workspaces)

Endpoint: GET /api/v1/workspace

curl -s -X GET "$INFISICAL_URL/api/v1/workspace" \
  -H "Authorization: Bearer $ACCESS_TOKEN"

Response: { "workspaces": [{ "id": "uuid", "name": "...", "environments": [...] }] }

2. HTTP Error Codes

Code	Meaning	Action
200/201	Success	Continue
400	Bad Request	Log the response body — likely malformed JSON or missing field
401	Unauthorized	Re-authenticate; token may have expired
403	Forbidden	Machine identity lacks permissions — check Infisical Access Control
404	Not Found	Secret or project doesn't exist
429	Rate Limited	Wait 60 seconds, retry once
500/503	Server Error	Log + retry once after 30 seconds; notify if still failing

Always check HTTP status before trusting response body:

HTTP_STATUS=$(curl -s -o /tmp/infisical_response.json -w "%{http_code}" ...)
if [ "$HTTP_STATUS" != "200" ] && [ "$HTTP_STATUS" != "201" ]; then
  # handle error
fi
RESPONSE=$(cat /tmp/infisical_response.json)

3. Sync State File Format

Stored at infisical_sync_state.json:

{
  "last_sync": "2025-01-15T10:30:00Z",
  "project_ids": ["uuid1", "uuid2"],
  "environment": "prod",
  "secrets": {
    "DATABASE_URL": {
      "hash": "sha256_of_key_plus_value",
      "version": 3,
      "last_synced": "2025-01-15T10:30:00Z"
    }
  },
  "error_count": 0,
  "push_count": 12,
  "pull_count": 47
}

Hash computation (to detect changes without storing values):

echo -n "DATABASE_URL:postgres://..." | sha256sum | awk '{print $1}'

Or with Python:

import hashlib
h = hashlib.sha256(f"{key}:{value}".encode()).hexdigest()

4. Vault Operations Reference

The local vault provides encrypted key-value storage. All secrets synced from Infisical go here.

Operation	Description
`vault_set key=K value=V`	Write or overwrite secret K
`vault_get key=K`	Read secret K
`vault_list`	List all keys (values not returned)
`vault_delete key=K`	Delete secret K

Bulk sync pattern:

// Pull from Infisical → vault
for each (key, value) in infisical_secrets:
    vault_set key=<key> value=<value>

// Optionally remove orphans
vault_list → local_keys
infisical_keys = set of keys returned by Infisical
for key in local_keys - infisical_keys:
    vault_delete key=<key>

5. Security Checklist

Before every sync cycle, verify:

INFISICAL_URL is set and non-empty
INFISICAL_CLIENT_ID is set and non-empty
INFISICAL_CLIENT_SECRET is set and non-empty
The access token was freshly obtained this cycle (never reuse across cycles)
No secret values appear in curl command echo output (use variables, not inline values)
Response body is never logged verbatim (strip secretValue fields before logging)

6. Common Failure Modes

"Failed to fetch secrets: 403 Forbidden"

The Machine Identity exists but lacks permissions. In Infisical:

Go to Access Control → Machine Identities
Find this agent's identity
Assign it the member role (or viewer for read-only) on the project

"Connection refused / Could not connect to server"

INFISICAL_URL is wrong or the instance is down. Verify the URL is reachable:

curl -s "$INFISICAL_URL/api/status" | python3 -c "import sys,json; print(json.load(sys.stdin))"

"invalid character in secret name"

Secret names in Infisical must match [A-Z0-9_]. If the vault has mixed-case keys, normalise before pushing:

echo "my_secret_key" | tr '[:lower:]' '[:upper:]'

"accessToken undefined in response"

Authentication failed. The response body will contain an error message. Check:

INFISICAL_CLIENT_ID and INFISICAL_CLIENT_SECRET are correct
The Machine Identity is not disabled in Infisical
The Machine Identity's token TTL hasn't been set to 0

7. Knowledge Graph Entities

Track fleet-wide secrets metadata without exposing values.

Entity types

service — the Infisical instance itself
secret_project — an Infisical workspace/project
secret — a named secret (key only, never value)

Relation types

secret → belongs_to → secret_project
secret_project → hosted_by → service
secret → synced_to → agent_vault

Query examples

knowledge_query type=secret                  // list all known secrets
knowledge_query type=secret_project          // list all projects
knowledge_query relation=belongs_to target=<project_id>  // secrets in a project
