Freshdesk API

Overview

Build integrations with Freshdesk's helpdesk platform using their REST API v2. Manage support tickets, contacts, companies, agents, and automate workflows. The API supports full CRUD operations on all major resources with filtering, pagination, and embedded data.

When to Use

• Building helpdesk integrations or support dashboards
• Extracting and analyzing support ticket data
• Automating ticket routing, assignment, or updates
• Syncing contacts/companies with CRM systems
• Creating custom reporting on support metrics
• Implementing chatbots or AI-powered support tools
• Migrating data to/from Freshdesk

Prerequisites

API Key Setup

1. Log into Freshdesk as an Admin
2. Click your profile picture → Profile Settings
3. Find your API Key on the right sidebar
4. Store securely (never commit to version control)

# Set environment variable
export FRESHDESK_API_KEY="your-api-key-here"
export FRESHDESK_DOMAIN="yourcompany"  # From yourcompany.freshdesk.com

Required Tools

• curl for HTTP requests
• jq for JSON parsing (brew install jq on macOS)
• For SDKs: Python 3.6+, Node.js 14+, or Ruby 2.7+

API Base URL

https://{domain}.freshdesk.com/api/v2/

Replace {domain} with your Freshdesk subdomain (e.g., acme for acme.freshdesk.com).

Authentication

Freshdesk uses HTTP Basic Authentication with your API key as the username and X as the password.

curl Example

# Using -u flag (username:password)
curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets"

# Using Authorization header
curl -H "Authorization: Basic $(echo -n "$FRESHDESK_API_KEY:X" | base64)" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets"

Headers

Always include:

Content-Type: application/json

Quick Start

    "email": "customer@example.com",
    "priority": 2,
    "status": 2
  }' \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets"

Get a Contact

curl -u "$FRESHDESK_API_KEY:X" \

Core Endpoints

See references/tickets-api.md for detailed ticket operations. See references/contacts-companies.md for contact/company management.

Rate Limits

Limits by API Version

Rate Limit Headers

Every response includes:

Handling Rate Limits

#!/usr/bin/env bash
# Retry with exponential backoff for 429 errors

max_retries=3
retry_count=0

while [ "$retry_count" -lt "$max_retries" ]; do
  response=$(curl -s -w "\n%{http_code}" -u "$FRESHDESK_API_KEY:X" \
    "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets")

  http_code=$(echo "$response" | tail -1)
  body=$(echo "$response" | sed '$d')

  if [ "$http_code" = "200" ]; then
    echo "$body"
    exit 0
  elif [ "$http_code" = "429" ]; then
    delay=$((2 ** retry_count))
    echo "Rate limited. Retrying in ${delay}s..." >&2
    sleep "$delay"
    retry_count=$((retry_count + 1))
  else
    echo "Error: HTTP $http_code" >&2
    echo "$body" >&2
    exit 1
  fi
done

echo "Max retries exceeded" >&2
exit 1

Credit System

Some operations consume multiple API credits:

• Basic request: 1 credit
• Including embedded data (include= parameter): +1 credit per include
• Example: ?include=requester,company costs 3 credits total

Pagination

Query Parameters

Example: Paginate Through All Tickets

page=1
while true; do
  response=$(curl -s -u "$FRESHDESK_API_KEY:X" \
    "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets?page=$page&per_page=100")

  count=$(echo "$response" | jq length)

  if [ "$count" -eq 0 ]; then
    break
  fi

  echo "$response" | jq '.[] | {id, subject, status}'
  page=$((page + 1))
done

Link Header

Responses include a Link header for navigation:

Link: <https://domain.freshdesk.com/api/v2/tickets?page=2>; rel="next"

Filtering and Embedding

Filter Parameters

Common filters available on list endpoints:

Pre-defined Ticket Filters

# New and open tickets assigned to me
curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets?filter=new_and_my_open"

# All unresolved tickets
curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets?filter=all_unresolved"

# Tickets updated in last 30 days
curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets?updated_since=2024-11-01T00:00:00Z"

Include (Embedding Related Data)

Embed related objects to reduce API calls:

# Include requester and company with ticket
curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets/123?include=requester,company"

# Include stats with ticket list
curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets?include=stats"

Available includes for tickets: requester, company, stats, conversations, description

Search API

The Search API enables complex queries across tickets, contacts, and companies.

Syntax

curl -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/search/tickets?query=\"<query>\""

Query Examples

# Tickets with specific status and priority
"status:2 AND priority:3"

# Tickets from a specific requester
"requester_email:'customer@example.com'"

# Tickets created in date range
"created_at:>'2024-01-01' AND created_at:<'2024-02-01'"

# Tickets with specific tag
"tag:'urgent'"

# Tickets assigned to specific agent
"agent_id:12345"

# Full-text search in subject and description
"~'password reset'"

Error Handling

HTTP Status Codes

Error Response Format

{
  "description": "Validation failed",
  "errors": [
    {
      "field": "email",
      "message": "It should be a valid email address.",
      "code": "invalid_value"
    }
  ]
}

Webhooks

Freshdesk can send webhook notifications on ticket events. Configure webhooks in Admin → Automations → Webhooks.

Event Types

• Ticket created
• Ticket updated
• Agent reply
• Customer reply
• Note added
• Ticket resolved/closed

Webhook Payload Example

{
  "freshdesk_webhook": {
    "ticket_id": 12345,
    "ticket_subject": "Support needed",
    "ticket_status": "Open",
    "ticket_priority": "Medium",
    "ticket_requester_email": "customer@example.com",
    "triggered_event": "ticket_created"
  }
}

See references/webhooks-automation.md for detailed webhook setup.

Best Practices

Performance

1. Use webhooks instead of polling - React to events in real-time
2. Batch operations - Use bulk endpoints when available
3. Cache static data - Agent lists, ticket fields rarely change
4. Use include parameter - Reduce API calls by embedding data
5. Paginate efficiently - Use max per_page=100 for bulk operations

Security

1. Store API keys in environment variables - Never hardcode
2. Use HTTPS only - All API calls must use HTTPS
3. Rotate keys periodically - Regenerate API keys every 90 days
4. Limit API key scope - Use agent accounts with minimal permissions

Reliability

1. Implement retry with backoff - Handle 429 and 5xx errors
2. Check rate limit headers - Pause before hitting limits
3. Validate responses - Check for error objects
4. Log API calls - Track usage and debug issues

Data Handling

1. Handle null fields - API returns nulls, not omitted fields
2. Parse timestamps as UTC - Format: YYYY-MM-DDTHH:MM:SSZ
3. Validate custom fields - Check field types before submission
4. Sanitize user input - Prevent injection in descriptions

Common Workflows

Export All Tickets to JSON

#!/usr/bin/env bash
# Export all tickets to tickets.json

page=1
echo "[" > tickets.json
first=true

while true; do
  response=$(curl -s -u "$FRESHDESK_API_KEY:X" \
    "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/tickets?page=$page&per_page=100&include=description")

  count=$(echo "$response" | jq length)
  [ "$count" -eq 0 ] && break

  if [ "$first" = true ]; then
    first=false
  else
    echo "," >> tickets.json
  fi

  echo "$response" | jq '.[]' | paste -sd ',' - >> tickets.json
  page=$((page + 1))
  sleep 0.5  # Respect rate limits
done

echo "]" >> tickets.json
echo "Exported $((page - 1)) pages of tickets"

Sync Contacts from CSV

#!/usr/bin/env bash
# Import contacts from contacts.csv (name,email,company_id)

while IFS=, read -r name email company_id; do
  curl -s -u "$FRESHDESK_API_KEY:X" \
    -H "Content-Type: application/json" \
    -X POST \
    -d "{\"name\":\"$name\",\"email\":\"$email\",\"company_id\":$company_id}" \
    "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/contacts"
  sleep 0.5
done < contacts.csv

Get Ticket Metrics

# Get resolution time stats for closed tickets this month
curl -s -u "$FRESHDESK_API_KEY:X" \
  "https://$FRESHDESK_DOMAIN.freshdesk.com/api/v2/search/tickets?query=\"status:5 AND created_at:>'2024-12-01'\"" \
  | jq '[.results[] | .stats.resolved_at as $r | .created_at as $c |
    (($r | fromdateiso8601) - ($c | fromdateiso8601)) / 3600] |
    {count: length, avg_hours: (add / length)}'
