Apideck REST API Skill

Overview

The Apideck Unified API provides a single REST endpoint to connect with 200+ third-party services across accounting, CRM, HRIS, file storage, ATS, e-commerce, and more. This skill covers direct HTTP usage for any language.

Base URL: https://unify.apideck.com

IMPORTANT RULES

• ALWAYS include the three required headers: Authorization, x-apideck-app-id, and x-apideck-consumer-id.
• ALWAYS make API calls server-side to prevent token leakage.
• USE x-apideck-service-id to specify which downstream connector to use. Required when a consumer has multiple connections for the same API.
• USE cursor-based pagination — iterate until meta.cursors.next is null.
• USE the filter query parameters to narrow results server-side. DO NOT fetch all records and filter client-side.
• USE the fields query parameter to request only the columns you need.
• DO NOT store API keys in source code. Use environment variables.

Authentication

Every request requires these headers:

| Header | Required | Description | |--------|----------|-------------| | Authorization | Yes | Bearer {API_KEY} | | x-apideck-app-id | Yes | Your Apideck application ID | | x-apideck-consumer-id | Yes | End-user/customer ID stored in Vault | | x-apideck-service-id | No | Downstream connector ID (e.g., salesforce, quickbooks) | | Content-Type | Yes (POST/PATCH) | application/json |

CRUD Operations

All resources follow a consistent URL pattern:

GET    /{api}/{resource}          → List
POST   /{api}/{resource}          → Create
GET    /{api}/{resource}/{id}     → Get
PATCH  /{api}/{resource}/{id}     → Update
DELETE /{api}/{resource}/{id}     → Delete

List

curl -X GET 'https://unify.apideck.com/crm/contacts?limit=20&filter[email]=john@example.com&sort[by]=updated_at&sort[direction]=desc&fields=id,name,email' \

  -H 'x-apideck-app-id: {APP_ID}' \

  -H 'x-apideck-service-id: salesforce'

  -H 'x-apideck-consumer-id: {CONSUMER_ID}' \
  -H 'x-apideck-service-id: salesforce'

Pagination

Apideck uses cursor-based pagination. Pass the next cursor from the response to fetch subsequent pages:

| Parameter | Type | Default | Range | |-----------|------|---------|-------| | limit | integer | 20 | 1-200 | | cursor | string | — | Opaque cursor from meta.cursors.next |

# First page
curl 'https://unify.apideck.com/crm/contacts?limit=50' -H '...'

# Next page
curl 'https://unify.apideck.com/crm/contacts?limit=50&cursor=em9oby1jcm06Om9mZnNldDo6NTA=' -H '...'

When meta.cursors.next is null, you have reached the last page.

Filtering and Sorting

Filters

?filter[field_name]=value

Available filters vary by resource. Common examples:

| Resource | Filters | |----------|---------| | CRM Contacts | filter[name], filter[email], filter[phone_number], filter[company_id], filter[owner_id], filter[first_name], filter[last_name] | | CRM Opportunities | filter[status], filter[title], filter[company_id], filter[owner_id] | | Accounting Invoices | filter[updated_since] (ISO 8601 datetime) | | General | filter[updated_since] for incremental sync |

Sorting

?sort[by]=updated_at&sort[direction]=desc

Field Selection

?fields=id,name,email,phone_numbers

Pass-Through Parameters

For connector-specific query parameters not in the unified model:

?pass_through[search]=overdue

For connector-specific fields in request bodies:

{
  "first_name": "John",
  "pass_through": [
    {
      "service_id": "salesforce",
      "operation_id": "contactsAdd",
      "extend_object": {
        "custom_sf_field__c": "value"
      }
    }
  ]
}

Error Handling

All errors follow this format:

{
  "status_code": 400,
  "error": "Bad Request",
  "type_name": "RequestValidationError",
  "message": "Human-readable error description",
  "detail": "Parameter-specific info",
  "ref": "https://developers.apideck.com/errors#requestvalidationerror"
}

| Code | Meaning | |------|---------| | 400 | Bad Request — invalid parameters | | 401 | Unauthorized — invalid API key | | 402 | Payment Required — API limit reached | | 404 | Not Found — resource does not exist | | 422 | Unprocessable Entity — validation error | | 429 | Too Many Requests — rate limit exceeded | | 5xx | Server Error — Apideck or downstream failure |

Rate Limiting

Apideck normalizes downstream rate limit headers:

| Header | Description | |--------|-------------| | x-downstream-ratelimit-limit | Total request capacity | | x-downstream-ratelimit-remaining | Remaining requests | | x-downstream-ratelimit-reset | Unix timestamp when limits reset |

Raw Mode

Append ?raw=true to include the unmodified downstream response in a _raw property alongside normalized data.

Available API Endpoints

| API | URL Prefix | Resources | |-----|-----------|-----------| | CRM | /crm/ | contacts, companies, leads, opportunities, activities, notes, pipelines, users | | Accounting | /accounting/ | invoices, bills, payments, customers, suppliers, ledger-accounts, journal-entries, tax-rates, credit-notes, purchase-orders, balance-sheet, profit-and-loss | | HRIS | /hris/ | employees, companies, departments, payrolls, time-off-requests | | File Storage | /file-storage/ | files, folders, drives, drive-groups, shared-links, upload-sessions | | ATS | /ats/ | applicants, applications, jobs | | Vault | /vault/ | connections, sessions, consumers, custom-mappings, logs | | Webhook | /webhook/ | webhooks, event-logs |

Webhook Events

Events follow the pattern {api}.{resource}.{action}:

crm.contact.created / .updated / .deleted
accounting.invoice.created / .updated / .deleted
hris.employee.created / .updated / .deleted / .terminated
file-storage.file.created / .updated / .deleted
ats.applicant.created / .updated / .deleted
