Authentication tokens for SDK and API access
API Tokens
Flaggr uses scoped API tokens for authenticating SDK and direct API requests.
Token Types
Project API Tokens
Project-scoped tokens for SDK and API access. Created in the project settings dashboard.
Authorization: Bearer flg_proj_xxxxxxxxxx
User JWT Tokens
Short-lived tokens issued during user authentication. Used by the dashboard and admin APIs.
Token Scopes
| Scope | Permissions |
|---|---|
read | Evaluate flags, list flags |
write | Create, update, delete flags |
admin | Manage project settings, tokens, members |
Creating Tokens
Via Dashboard
- Navigate to Project Settings > API Tokens
- Click Create Token
- Select the required scopes
- Copy the token immediately (it won't be shown again)
Via API
curl -s -X POST https://flaggr.dev/api/projects/proj-1/tokens \
-H "Authorization: Bearer $ADMIN_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"name": "production-reader",
"scopes": ["read"],
"expiresIn": "90d"
}' | jq
# Response includes the token value — save it immediately
# {
# "token": { "id": "tok_...", "name": "production-reader", ... },
# "value": "flg_proj_xxxxxxxxxxxxxxxxxxxx"
# }Verifying a Token
After creating a token, verify it works by evaluating a flag.
curl -s https://flaggr.dev/api/flags/evaluate \
-H "Authorization: Bearer flg_proj_xxxxxxxxxxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{"flagKey":"checkout-v2","serviceId":"web-app"}' | jqToken Rotation
Tokens can be rotated without downtime:
- Create a new token with the same scopes
- Update your application configuration
- Delete the old token
Revoking Tokens
curl -s -X DELETE https://flaggr.dev/api/projects/proj-1/tokens/tok_old_token_id \
-H "Authorization: Bearer $ADMIN_TOKEN" \
-H "X-CSRF-Token: $CSRF_TOKEN"Security Best Practices
- Use
read-only tokens for client-side SDKs - Set expiration dates on all tokens
- Rotate tokens regularly (every 90 days recommended)
- Never commit tokens to version control
- Use environment variables for token storage
- Use separate tokens per service/environment
